Presented by Kristine Nichols, Ph.D., Soil Microbiologist, USDA Agricultural Research Service Soil as the heart of the farming ecosystem is driven by biological activities to increase soil organic matter, which represents a small percentage of the soil by weight, but controls over 90% of the soil functions. This presentation introduces viewers to the concepts of 1) rhizosphere biology, the area immediately surrounding the plant root with the highest concentration of microbiological activity; 2) soil "livestock" consisting of bacteria, fungi, nematodes, protozoa and microarthropods and representing the greatest concentration of biomass anywhere on the planet; 3) glomalin, a biological glue that holds soil together and improves soil aggregation; and 4) building soil biota to improve soil quality, increase nutrient cycling, and long term sustainability using cover crops, no-till, and other sustainable farming practices.

Participants in this webinar will learn about the biological importance related to soil health management. Advantages and limitations for a variety of biological soil health indicators will be discussed including how they are measured and may be interpreted. As momentum and interest in soil health and soil health management practices grows across the country, farmers, crop consultants, NRCS field staff, and land managers are looking for ways to assess the status of soil health on their fields. The actions performed by the soil biota help to promote soil health by enhancing plant productivity, building stable aggregates, capturing and storing carbon, release of plant-available nutrients, and detoxifying soil pollutants. There is a great need to identify tools to help direct land management practices that help to support a healthy, diverse, and active soil community. This webinar will explore how soil biota contribute to soil health and high functioning soils and methods currently in use to measure soil biological indicators. However, no one approach is perfect. The advantages and limitations for a variety of these methods will be presented to help audience members better understand how to use them and interpret their values as well as be aware of new tests that are being investigated. This webinar is presented by USDA NRCS Science and Technology. Captions will be posted when they are available.
Dr. Nikki Seymour covers an introduction to soil biology and why it is important for crop and soil health. Specific reference to impacts of agricultural practices on soil biological components and how this might relate to crop productivity are covered.

Polycyclic aromatic hydrocarbons, commonly referred to as PAHs, are a group of chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances like tobacco or charbroiled meat. PAHs are often found as a mixture containing two or more of these compounds. Some PAHs are also manufactured. These pure PAHs usually exist as colorless, white or pale yellow-green solids. PAHs are found in coal tar, crude oil, creosote and roofing tar, and a few are also used in medicines or to make dyes, plastics and pesticides. These chemicals have been found in at least 600 of the 1,430 National Priorities List sites identified by the Environmental Protection Agency (EPA). People can be exposed to PAHs by: • Breathing air containing the chemicals in the workplace of coking, coal-tar, and asphalt production plants; smokehouses; and municipal trash incineration facilities. • Breathing air containing PAHs from cigarette smoke, wood smoke, vehicle exhausts, asphalt roads or agricultural burn smoke. • Coming in contact with air, water or soil near hazardous waste sites. • Eating grilled or charred meats; contaminated cereals, flour, bread, vegetables, fruits, meats; and processed or pickled foods. • Drinking contaminated water or milk. • Nursing infants of mothers living near hazardous waste sites may be exposed to PAHs through their mother's milk. The Department of Health and Human Services (DHHS) has determined that some PAHs may reasonably be expected to be carcinogens. Some people who have breathed or touched mixtures of PAHs and other chemicals for long periods of time have developed cancer. Some PAHs have caused cancer in laboratory animals when they breathed air containing them (lung cancer), ingested them in food (stomach cancer), or had them applied to their skin (skin cancer). These are just a few things to know about PAHs, to learn more about this or other indoor air quality, environmental, health and safety issues, please visits the websites shown in the video.

QAAFI Science Seminar -- 24 June 2014 By Prof. Susanne Schmidt http://www.uq.edu.au/agriculture/susanneschmidt Please note: Near the end of this presentation, Prof. Schmidt refers to a YouTube video, which can be viewed here: https://www.youtube.com/watch?v=CReaedEF41w ABSTRACT Nutrient management is the Achilles Heel of modern agriculture with too little or too much determining the fate of crop yields and environmental health. We research nutrients from the soil up. Soil biology, plant physiology and biogeochemistry research are integrated from controlled experimental systems to discover fundamentals to industry relevant field based research, our research is wedged firmly between ecology and agriculture. With nitrogen pollution considered to have long surpassed the global boundaries of the safe operating space, reactive nitrogen has nearly tripled in the past century (by comparison, human perturbations of the global carbon cycle amount to around 5%). Nitrogen pollution is not a new problem, yet it is far from being solved. How can we increase yields but avoid pervasive pollution footprints that characterise high-yielding production systems? In this presentation, Prof. Schmidt will discuss global knowledge in context of activities aimed to address the problem of nutrient pollution using sugarcane as example that we have been working on for a decade. Prof. Schmidt will take you on a tour from the Incas, through to the modern farm. Susanne leads projects on plant selection, nutrient use efficiency, biogeochemistry and novel uses of native plants.

Description: Sustainable agriculture is a holistic form of farming; it takes from an ecosystem without damaging or impairing it. Wild plants are more tolerant and robust than sensitive cultivated plants. Scientists have tweaked sensitive crop plants in an attempt to make them more robust in an attempt to reduce chemical use. Chemical fertilisers are measures used by farmers, that cannot replace a rich thriving ecosystem and have an accumulative effect on the soil and imbalances its natural components/properties as well as being toxic to animals (and us). Scientist are trying hard to find answers ..............Scientists say that species extinction rates are higher than the normal background rate . The undiscovered and unknown are also being lost. Scientists are under pressure to devise ways to meet global demands for foods and fuel. Geneticists are trying to devise ways to genetically engineer hardier crops in order to produce adequate yields. Taking care of and replenishing our ecosystems may be the long-term answer, but there is no quick fix. World population is expected to exceed 8 billion by the year 2030.

See the full video feature here: http://ht.ly/R2SoT Around one third of the food ever grown is destroyed by pests or pathogens. Part of the food security challenge is to grow food using less inputs, such pesticides. But there are relatively few studies that directly compare both techniques at the farm level. So Professor Jane Memmott and colleagues at the University of Bristol decided to look at the differences in biodiversity between conventional and organic farms at the farm-scale, and then see which was better at controlling pests.

Technical Video Presentation for National Chemical Engineering Symposium (NACES) 2017 by Universiti Sains Malaysia. Summary: Inland aquaculture contributes to 70% of total global fish production resulting competition for natural resources (water, land) and environmental problems such as eutrophication. Eutrophication happens when water body is concentrated with nutrients from the use of fertilizers. As an outcome, the algal blooms limit the amount of dissolved oxygen required for respiration by aquatic species. When the dissolve oxygen reaches hypoxic levels, the aquatic biota suffocate to death. This can bring about aquatic dead zones and lessens biodiversity. Aquaponics is the combination of aquaculture and hydroponics that grows fish and plants together in one integrated system. Waste is something which is discarded after the completion of a process with no further purpose. Fish waste provides an organic food source for the plants, and the plants naturally filter the water for the fish. Nitrifying bacteria, Nitrosomonas metabolize the ammonia and promotes its oxidation to nitrite ions. Whereas, Nitrobacter oxidize nitrites to nitrates for the plants intake. In combining both hydroponic and aquaculture systems, aquaponics capitalizes on their benefits, and eliminates the drawbacks of each. Aquaponics recycle the water in the system, hence, we can grow in droughts and areas with little water. It uses only 1/10th of the water of soil-based gardening. No harmful petro chemicals, pesticides or herbicides is used. Thus, inhibiting eutrophication. Also, channelling of accumulated non-toxic products to secondary crops can become an additional profit. Besides, it also saves a big lot of space. Thus, making it a sustainable solution to our environmental problem.

Sustainable agriculture 12 STANDARD BIO BOTANY Higher Secondary Second Year BIOLOGY https://www.padeepz.net/12th-standard-bio-botany-higher-secondary-school-tamil-nadu-state-board-syllabus-audio-explanation-important-question-paper-bank/ Increased food production in India was made possible by the employment of modern technology in agriculture. The increase in the productivity is mainly due to rapid rise in overall area under cultivation of cereals. To maintain the crops and productivity, we have to expand irrigation facilities and use large amounts of fertilizers and pesticides. This overexploitation had resulted in the degradation of soils and their erosion. Due to degeneration in soil fertility, the traditional varieties of crop plants as cultivated in earlier periods got disappeared or are on the brink of extinction. Our agriculture is slowly being converted into an unsustainable system in the years to come, as the cost of chemicals and fertilizers, labour, cost of seeds are going to make the agricultural products costlier. This will affect millions of uneducated farmers. Hence, to remedy this situation, we will have to find alternative permanent arrangements in sustainable agriculture. To protect the interest of the farmers on their agricultural lands and capital investments, sustainable agriculture which is the best source of alternative method should be compulsorily taken up and practiced by the traditional farmers. Sustainable agriculture can be carried on without any threat to our soils, environment, plants and animal communities. Excessive drainage of our energy and material resources can be considerably saved and protected when sustainable agriculture is intensively taken up by the farmers and practiced. This can be achieved by 1. Maintaining a healthy soil community which can automatically regenerate soil fertility by providing organic manures, increasing fallow periods, avoiding excessive use of chemical fertilizers and pesticides. 2. Infusing bio-diversity in agriculture by sowing mixed crops, crop rotation etc. 3. The use of alternative food sources which may reduce overdependence to certain crops. Men are exploiting only few species of crop plants as food and cultivate only about 15 species of plants as food crops to feed 90 per cent of the world’s population. There are thousands of species of plants with useful and edible parts which can serve as a food source for the mankind. This will widen our resource base on food crops and add sustainability to supplies by reducing the dependence on a few species. eg. Winged bean which has high protein and oil. Leaves of Ilex paraguriensis, which can be a substitute for tea and powdered seeds of Cola nitida instead of coffee. Farmers should practice ‘organic farming’ so that it will not disturb the ecosystem of the cultivable area and leads to sustainable yields at low costs, both to the farmer and to nature. Chemicals, minerals, pesticides and insecticides are now categorised under non-renewable resource materials. Therefore, in the long-term strategy, these materials will make farming non-sustainable and non-productive. Shifting to original and excessive use of organic manure, rotation of leguminous or nitrogen fixing crops, use of VAM fungi, transgenic crop and application of biofertilizer are being encouraged and practiced. Sustainable agriculture includes scientific methods of farming that utilise renewable resources, increase in yield, avoidance of manmade complex substances known as Xenobiotics which are used as insecticides and pesticides that cause pollution to soil and environment. Plant tissue culture and biotechnology also play a major role in this. 50 varieties of rice and 20 varieties in wheat have been developed in China by using these new techniques without damaging the environment. New disease resistant virus free plants and stress resistant plants, are successfully produced. Similarly, transfer of nif (nitrogen fixing) gene to nonleguminous crops will improve higher yield. Biotechnology and tissue culture contributed more to sustainable agriculture by providing biofertilizer, biopesticides, disease and insect resistant varieties through creation of transgenic crops, single cell protein, production of valuable pharmaceutical products and herbal drugs (Ginseng Vinca, Emetine from Cephalis) by using micropropagation technique. To conclude Sustainable agriculture is an eco-friendly farming system associated with production of food while maintaining on biophysical resources including soil, water, biota with no adverse impacts on the environment. So it should 1. maintain or improve the production of clean food. 2. maintain or improve the quality of landscape which includes soil, water, biota and aesthetics 3. have minimal impact on the environment. 4. be economically viable and 5. be acceptable to society.

Order Wood Vinegar: New Life Wood Vinegar United States www.woodvinegarusa.com 1 (888) 242 1267 Why Try using Wood Vinegar Why use Wood Vinegar? - High density liquid – “freight costs vs coverage” that fits into existing supply chain infrastructure - Value adds to a growing char manufacturing industry - A possible sustainable supply source - Extensive use throughout Asia for many decades must have merits - High potential to reduce dependency on limited expensive ag chemicals - Potential to largely and cheaply increase seed germination strike rate Wood Vinegar Complements Agricultural Chemicals With respect to diseases of stems and leaves, many researchers claim that wood vinegar both has a direct germicidal effect, and an indirect, prophylactic effect through changing the biota on the leaf surface. When leaves are temporarily acidified, it prevents the increase of germs. However, the most conspicuous benefit of spraying wood vinegar on leaves is the vinegar’s ability to strengthen plants’ natural resistances to diseases and to increase the permeability of agricultural chemicals. Many researchers point out that leaves on which wood vinegar is sprayed turn glossier and greener. They postulate that this is because certain kinds of esters in wood vinegar increase the levels of chlorophyll and stimulate photosynthesis. It is also presumed that they assist in the synthesis of sugars and amino acids. As a result, in addition to increasing leaf vitality and thus resistance to disease, wood vinegar can also actually improve the taste of agricultural produce. In addition, wood vinegar increases the permeability of agricultural chemicals into leaves. Such chemical usually dissolve most easily in acids with pH value of 4 to 5. Therefore, when they are sprayed together with wood vinegar, they become more effective. In this way, the quantity of agricultural chemicals used, and the frequency with which they are used, can often be reduced by half. However, alkaline agricultural chemicals cannot be mixed With wood vinegar because they react negatively with the acids in the vinegar. Order Wood Vinegar! Increased Sugar Levels and Growth Stimulation Another major benefit of wood vinegar is that it appears to assist the enzymes and microbes which facilitate plant cell growth and other useful reactions. While this mechanism is unclear scientifically, many researchers claim that spraying wood vinegar makes plants take root more firmly, helps leaves grow larger and fuller, counteracts excessive nitrogen, stimulated the metabolism of plants and raises sugar levels. It is assumed that plants are favorably affected by trace elements in the wood vinegar, or other substances produced when wood vinegar is decomposed through the photosynthetic process. Spraying wood vinegar diluted 500 to 1000 times an improve the taste of fruits that are not very sweet due to weak photosynthesis resulting from a lack of sun or poor soil. This effect is assumed to be due to wood vinegar’s role as a coenzyme. It is also thought to be related to the presence of esters in wood vinegar. Valerianic acid ethyl, for example, benefits the growth of radish and of Chinese cabbage. Such esters in wood vinegar as methyl acetate andmethyl formate also have a strong growth acceleration effect on plants. Wood Vinegar helps Fertilizer Just as wood vinegar increases the effectiveness of pesticides and herbicides, it also increases the effectiveness of fertilizer. This is due to the fact that wood vinegar complements both the fertilizer and the existing soil nutrients. For example, it has been recorded in applications of wood vinegar in the growing of tea that it increases by three times the level of useable phosphoric acid. The roots of plants secrete organic acids which dissolve and absorb phosphoric acid in the soil, and it is thought that organic acids in wood vinegar have the same effect.

In this episode, they discuss with IRRI Entomologist Finbarr Horgan - http://irri.org/index.php?option=com_k2&view=item&id=8603:finbarr-horgan&lang=en - if insects might be a problem in their plot. Commentary from Dr. Dobermann: 2 February: "As a purist, I can't be satisfied by how uneven our crop looks. The small patches with few or no plants we see scattered throughout the field are a stark reminder of what went wrong early on. But it's tillering time and we still have hopes that some may fill more. That's one of the fantastic features of rice -- it can tiller profusely when it has a lot of space to fill. Leigh says the best thing to do is to walk away for a couple of weeks and not worry about it. I won't go that far. We were out there this morning with Finbarr Horgan, our entomologist, to look at actual and potential insect problems we may face. For most people, insects tend to have a bad reputation and when they see them in the field, a natural reaction is that they must be doing something bad to the young, juicy rice plants. You don't see a lot when you're standing outside the field, but once you go in and stare down a little closer you'll find a whole biological microcosm in and around the shallow water layer and rice plants. Watch the video clip to see some of the critters we found this morning. Amazing stuff, particularly if you have somebody around who can tell you what all these things are and what they do. Many rice farmers in Asia still have a tendency to spray insecticides whenever they see some damage on the rice leaves, particularly at early growth stages during the first 5 to 6 weeks after planting or sowing. This is almost always the wrong thing to do. Yes, we also found a little bit of leaf damage by insects such as the whorl maggot (a fly) or leaffolders, but it rarely causes a major yield loss - and we saw lots of "good" insects, those that are natural enemies of the pests we may be worrying about. Spraying now, particularly with a broad-spectrum insecticide, would have the opposite effect because it would also kill most of the beneficial insects we need to keep for biological control through the normal food webs. So, we're happy to make that decision: no need to spray at this stage. That's also what our guidelines for Integrated Pest Management (IPM) say. What has cropped up as a new problem are perennial grasses that have spread from the bunds into the field. In fact, much further than we had thought possible. We had no choice but to hire eight laborers for a couple of hours to do handweeding right away. Not good for the balance sheet, but it may also mean that we may not need to spray a post-emergence herbicide." 6 February: "With profuse tillering ongoing, it's time to apply the first topdressed nitrogen, as recommended in our site-specific fertilizer prescription. I came out yesterday morning to drain off the surface water. Why? We'll be using urea and applying it on a wet soil surface followed by re-irrigation will greatly enhance the efficiency of the fertilizer. Urea dissolves quickly and the water will move it into the root zone, where the rice plants can take it up quickly, as much as 5 kg N per ha per day at this stage. What's not taken up gets absorbed as ammonium on clay particles in the soil or consumed by microbes -- or is lost. The latter is what we want to avoid. If we would drop a large amount of urea into the standing floodwater layer, the risk is great that a lot of it gets converted to ammonia gas and thus lost to the air rather than going into the plant, where we want it to go. Scientists spent a lot of time in the 1980s to figure out the biological and chemical processes behind all that. It all has to do with a large increase of the pH in the floodwater during daytime, when algae are biological most active. Our rate was 2 bags of urea per ha, or half a bag for our field (46 kg N/ha). We roughly quartered that amount into buckets and spread it. How evenly we'll see in just a few days. Nowadays, urea is of much better quality than it used to be. It's more granular and less prone to becoming sticky or caked up than the prilled urea that was common 30 years ago. If you spread it by hand, you appreciate that difference immediately. Water has gone back on at about 5-cm depth. From now we'll stick to the alternate wetting and drying (AWD) water management we had planned to do."

Links CONTACT: [email protected] The industrial agriculture “feed the world” myth — Local Food Northland http://wp.me/p5Cqpo-fN7 The Alliance to Feed the Future King Corn **** This is the World Organic News for the week ending 31st of July 2017. Jon Moore reporting! This week we are focusing on post from the blog Local Food Northland entitled The industrial agriculture “feed the world” myth. The myth discussed in this video and written presentation is the “We need industrial agriculture to feed the world now and into the future.” This myth is prevalent, usually unchallenged and wrong. It is supported in the US by The Alliance to Feed the Future. I’ve put a link in the show notes. It worth a look just to check the members page. Here we find such health food producers as the National Frozen Pizza Institute, the Association for Dressings and Sauces, Flavor and Extract Manufacturers Association of the United States, The Fertilizer Institute, Grocery Manufacturers Association, International Association of Color Manufacturers, National Confectioners Association and Shelf-Stable Food Processors Association to name a few from the list of members. You can see a certain pattern in these members. They are not localised, wholefood types. Shelf-Stable Food Processors Association are not in existence to breed better tasting, longer shelf life tomatoes as much as they are developing better chemical preservatives to maintain the look but not necessarily the health properties of food, certainly not wholefoods. They were originally formed in 1923 as the National Meat Canners Association. There is a list of their aims and the fourth aim is: Quote: to inform the trade and public of the advantages of processed food product usage; End Quote Given the history of excessive salt, fat and sugar useage in the processed food sector, these might not be the best source of information on the best way to feed the world. I’m not picking on the Shelf-Stable Food Processors Association, the National Confectioners Association is probably not a better source of information on farming and food production either. So, let’s look the system of production The Alliance to Feed the Future is advocating for. It is the industrial, Henry Ford inspired, ways of doing things. As I’ve argued elsewhere, the Ford system is great for producing widgets and turning employees into robots but food production involves far more living things. A carrot seed is not pig iron. To begin at the beginning: Seeds. In the industrial system seeds are highly interbred to produce hybrid types with certain characteristics. These characteristics are chosen to create a level of uniformity suitable to industrial processes. I’ll cover alternative methods and choices later but stay with me on this journey. These seeds are sold on a one use only basis. Collecting a portion of this year’s crop to replant next year is not an option for at least three reasons. One: as hybrids they will not continue to grow true to type each year as the founding cultivars will exhibit their growth patterns over the years. This will result in very uneven growth rates, maturation rates and so on, Two: quite often and increasingly, these seeds are design to be infertile in the next generation. This is especially so with vegetable seeds. A friend saved the seeds from a halloween pumpkin so I could regrow them for her the next season. All of the flowers were male and therefore incapable of forming fruits. And lastly Three: producers are being forced to sign agreements as part of the conditions of seed purchase which prohibits them from seed saving and re-sowing. Now that the farmer has these seeds in their soil, it turns out they are designed to grow with application of chemical fertilisers and water and set times. It just so happens that many of the seed sellers also sell fertilisers. Happy coincidence. To obtain the greatest possible yield to cover the costs of these one off seeds, the necessary fertiliser and any pesticides to save their investment, monocultures are not only encouraged but probably essential to obtain a return. Podcast sidebar: Monocultures are the growing on one cultivar of one crop in one continuous paddock. The downsides of this are: a huge banquet has been laid for insects, herbivores and diseases which specialise in that crop. The one crop takes a particular set of nutrients from the soil. When the same crop is grown over and over on the same piece of land, more chemical fertilisers are required to obtain the same yield. Chemical fertilisers have been shown to kill off soil biota, leading to the need for more fertilisers and the loss of topsoil. A win/win for the fertiliser manufacturers but a growing spiral of increasing costs for the farmer. End podcast sidebar. The end effect of everyone growing the same crop, producing...

KMS Kms is a tropical island, located in the Atlantic Ocean. Abiotic factors - The climate is warm and sunny year round. It rains about twice a week for a few hours. Has sand, but dirt and soil on the inland. Lots of water because there is beach all around. Grows lots of trees, but very few species. PRODUCER : eats photosynthesis Macaroni Range - lives all over the island Population - 17,000 Reproduction - asexual, seeds fall over and get blown in the wind and buried which grows a new tree, grows all the time except winter Nutrition - autotroph, biotic. Needs sunlight and warm weather to live. Eaten by leprechaun and platypus Environmental Insults - weather that is too cold will kill it PRIMARY : eats producers Perry the Platypus Population - 7,369 Habitat - the ocean Is eaten by - secondary and decomposers Interaction - speaks a different language than the other animals Adaption - good swimmer Reproduction - sexual, has live birth, attracts mates by giving them sexy vibes Nutrition - tree (insert name) and water Environmental Insults - if they eat meat they go into anger mode SECONDARY : eats producers and primary Leprechaun Population - 10,000 Habitat - lives inside the trees Is eaten by - higher and decomposers Interaction - gives others positive energy Adaption - is very small to fit inside the trees Reproduction - sexual, hides the eggs all over the island, attracts mates by putting a pot of gold in front of a door and the girl who lives there will either throw something at them or invite them inside Nutrition - has to eat platypus Environmental insults - negative energy makes them choke HIGHER : eats secondary, and decomposers Meatball Man Population - 420 Habitat - lives in the trees Is eaten by - decomposers Interaction - friendly but has a dark side Adaption - very fast tree climber Reproduction - sexual, has live meatball babies in the tree branches, attracts mates by waiting for them to come Nutrition - needs leprechauns to live Environmental Insults - if it eats too many leprechauns it explodes DECOMPOSER : eats higher, secondary, primary Shrek Population - 6517 Habitat - lives under the sand Is eaten by - higher Interaction - is an angry boy Adaption - can breathe sand, eats it when depressed Reproduction - sexual, lays eggs buried in the sand, attracts mates by screaming Nutrition - needs sand and dead meat which sinks into the sand Environmental Insults - if it looks into the sun and screams for 10 seconds, it becomes a happy vegan Environmental change When cold climate change comes, it causes macaroni to die. This takes away the meatball man and leprechaun’s home. The water becomes too cold and there is no food for them, so the platypus leave to find warmer water. Now that there is no trees or platypus left, there is nothing for the leprechaun to eat, so they all die. Impact on species Extinct: Leprechauns- The Leprechauns eventually become extinct because there is nothing for them to eat. Macaroni - It is too cold for the trees to survive. Endangered: Meatball man- The meatball man’s home is gone and now only has one food source left. Threatened: Perry the platypus- The water is too cold and their food is gone so they have to leave or they will die. No change: Shrek-The shreks won’t change because they still have both a food source and a home. Increased: Shrek- After time the shrek will increase because there is a lot of dead things for them to eat. Mitigation: To prevent extinction of macaroni, new species of trees can be planted on the island that are more resistant to cold. This will be provide the leprechauns and meatball man with a home, and the leprechauns with food. You could also get shrekticides (pesticides) for shrek to kill some of them, so that the meatball man don’t get eaten.

Tamarisk infestations often have strongly negative effects on the biotic communities at invaded sites, especially on the plants that persist underneath the tamarisk canopy and nearby. Tamarisk removal may eliminate the physical impacts of infestations, but may also cause unintended consequences that can define how well understory and surrounding plant communities can re-establish. Our ongoing research studies how common tamarisk removal and control methods (chemical control -- aerial and backpack applications; mechanical control -- Hydro-axe mulching and tree excavation; and biological control -- Diorhabda carinulata releases) affect patterns of subsequent site re-vegetation. Imazapyr and triclopyr are the two most frequently used herbicides for controlling tamarisk. Therefore, our research has focused on the effects from initial herbicide applications and also on the impact of soil residues. Helicopter applications of imazapyr resulted in widespread plant community decline, with kochia being the most common and abundant species that establishes following application. Individual plant applications of imazapyr minimized the area of non-target impacts, but still killed many plant species. Triclopyr basal bark applications were much safer on the understory plant community, and in particular for grasses. The soil residues of imazapyr in particular were persistent, and twelve months after application negatively affected sensitive native plant species. Mechanical removal methods tended to have a short-term positive effect on plant communities, increasing species diversity and numbers. Interestingly, the small-sized tamarisk debris created by Hydro-axing and other mulching equipment was found to encourage initial plant establishment. However, by the second year after treatment the disturbances caused by mechanical tamarisk removal favored recruitment by perennial, invasive species. Species that were found to be especially common and problematic included perennial pepperweed and Russian knapweed. Overall, while tamarisk removal by any means can at some sites facilitate the establishment of other noxious plants, there is generally an inherent ecological capacity for desirable and functionally important plants to establish. The specific removal method that is chosen can affect this capacity, and the broad use of non-selective herbicides in particular can diminish desirable re-vegetation. Secondary establishment by other invasive plant species can often be managed efficiently and successfully if identified early on when infestations are small and easy to treat. Controlling tamarisk is only one component of effectively managing infested natural area sites, and the selection and implementation of appropriate removal methods can help to preserve a site's capacity for passive restoration.

Presented by Gene Hardee, Agronomist (retired 7/2012), USDA NRCS East National Technology Support Center The rate, source, placement, and timing of plant nutrients and soil amendments are major determinants of nutrient utilization efficiency. However, efficiency in nutrient utilization is also influenced by the cropping system through its impact on nutrient availability and needs, potential nutrient loss or removal pathways, and the need for and feasibility of specific nutrient management techniques. Increased potential for movement of nutrients via some loss pathways has been raised as a concern with continuous no tillage systems by some scientists and other specialists. Such assumptions may not explore the variation in no-till systems, the total resource benefits of no tillage, or the impacts of other important supporting practices and components of the no-till cropping system. This webinar examines nutrient management under continuous no tillage, including soil sampling and interpretation, nutrient pools in no-till systems, impact on nutrient availability and loss pathways, and companion practices to further mitigate nutrient loss potential.

Stay Tuned & Subscribed https://goo.gl/Vrf7gQ The National Green Tribunal (NGT) rapped the Punjab government for not incentivizing the farmers, or assisting them in managing the crop residue, earlier this month. The residue is estimated to be around 35 million tonnes, and is currently being set ablaze by farmers, to make up for the short window between winter and summer crops. The government informed the NGT that, it had been helping the farmers to manage the residue, without burning, and provided assistance to 21 farmers in Kalar Majri village of Patiala district. To test this claim of having supported 21 farmers, in managing the stubble in a sustainable manner, without burning, the National Green Tribunal directed the State government to bring these farmers before it on October 13. On October 11, the bench headed by NGT Chief Justice Swatanter Kumar, heard a petition filed by Punjab farmers who alleged that the government was not doing anything to help them or carry an awareness campaign against stubble burning. The petitioners, who belonged to Bhartiya Kisan Union-Rajwal, also averred that the government had approached them in the first week of September with ‘warnings and threats’, instead of assistance. Over 100 farmers gathered outside the National Green Tribunal and rebuffed the claim made by the latter, about reverse ploughing to be mixed in the residue with lower layer of soil. As stubble burning in neighboring states has direct impact on Delhi’s air, the National Green Tribunal, in 2015, had asked the Delhi, Punjab, Haryana, Uttar Pradesh and Rajasthan governments to curb this practice. It had also asked the governments to incentivize small farmers to manage the stubble, without burning.

LINKS What I said at the NOSB meeting last week http://wp.me/p5Cqpo-eU7 UNFI Foundation http://www.unfifoundation.org/Pages/MissionandPriorities.aspx Soil carbon 'a saviour' in locking up carbon http://www.abc.net.au/radionational/programs/scienceshow/soil-carbon-%E2%80%98a-saviour%E2%80%99-in-locking-up-carbon/8460928#transcript Strezelechi **** This is the World Organic News for the week ending 1st of May 2017. Jon Moore reporting! I’d like to start this week with a big thank you to dsearlybird12’s comment on Podbean: “interesting and pertinent”! Thank you! Now to the blog: Organic Matters by Melody Meyer and a series of posts on the National Organic Standards Board. Melody spoke on behalf of United Natural Foods. She spoke about the need for market driven solutions within the organic food sector. Quote: It’s the dollars and cents, the economic growth that organic represents for producers, manufacturers and retailers. For consumers, it’s the option to have an informed choice through the USDA label. Expanding and preserving that choice helps consumers avoid persistent pesticide exposure. It helps correct the environmental degradation of non-organic production methods. End Quote. I found this thought provoking. The “market” in inverted comments is a social construct. Defined by the governments of the world, the rules for markets are decided, not so much by Adam Smith’s unseen hand, but by that unseen hand operating within the rules decided in unseen smoke filled back rooms. So with a little tweaking and whole lot of subsidy redistribution, the market could be made to work for rather than against the organic movement. The way the system is set up now, farmers who do not use poisons have to spend thousands to prove this is the case. Those farmers who regularly douse their crops in poisons, pesticides, herbicides and artificial fertilisers are free to sell whatever they want based on the 50% death rules. 50% death rules? I hear you ask. Yes. A poison is determined safe for human consumption on the following basic idea. Lab rats are fed a poison. The length of time it takes to kill half of them is the key to human food safety. Once the 50% death rate is reached, a conclusion is reached and the remaining 50% of surviving rats are euthanized. There are, therefore no data on long term effects of these poisons only their immediate acute effects. Sounds like a system designed for chemical manufacturers rather than human food consumers. Changing these rules of the market would immediately increase the safety of foods and give the organic sector a huge boost. I would suggest as individuals the way to overcome this bias and the many others embedded in the non-judgemental, values free, “market” which determines the best price for both consumers and suppliers, is to avoid anything, and I mean anything which does not have a certified organic label. Now there may be perfectly safe insecticides out there but we have no way of knowing giving the testing regime currently in place. Who knows how safe the cockroach and spider sprays are that are used on homes, well used on all buildings really. We are after all inhabiting these structures, not ingesting them until half of us drop dead! Now to the other end of the food system, the soil! This from an interview with Robin Batterham, a former federal chief scientist in Australia. Robin was a guest on the long running Radio National program the Science Show. The title for this interview gives us a clue: Soil carbon 'a saviour' in locking up carbon. Now the science around soil carbon is messy. The soil is, after all, a living thing. Quote: It is not fully understood, far from it, although with genetic typing these days we can understand much more of the thousands of interactions that go on. That's one whole side which is how do you encourage more of the bacteria and the fungi so that you get actually more carbon in the soil, you get greater root penetration, you get greater water retention and so on. End Quote. Robin’s argument is that we have sufficient knowledge, if not the ability to accurately measure soil carbon to starting the process of moving agriculture from artificial fertilisers and poisons to regenerative agriculture. Noting the following ways soil carbon is lost: Quote: We lose it essentially by two methods. One, we clear native vegetation and turn it into intensive agriculture. That almost inevitably results in loss of carbon from the soil. That's one. The other is that by extensive use of tilling, which changes the oxidative state of the soil and changes the balance between fungi which tends to not want it to be too oxidative and bacteria, by use of pesticides which similarly affect the biota, by use of extensive fertiliser application in a form which is not readily absorbed by plants, we just slowly, surely grind carbon...

What is ECOLOGICAL RESILIENCE? What does ECOLOGICAL RESILIENCE mean? ECOLOGICAL RESILIENCE meaning - ECOLOGICAL RESILIENCE definition - ECOLOGICAL RESILIENCE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ In ecology, resilience is the capacity of an ecosystem to respond to a perturbation or disturbance by resisting damage and recovering quickly. Such perturbations and disturbances can include stochastic events such as fires, flooding, windstorms, insect population explosions, and human activities such as deforestation, fracking of the ground for oil extraction, pesticide sprayed in soil, and the introduction of exotic plant or animal species. Disturbances of sufficient magnitude or duration can profoundly affect an ecosystem and may force an ecosystem to reach a threshold beyond which a different regime of processes and structures predominates. Human activities that adversely affect ecosystem resilience such as reduction of biodiversity, exploitation of natural resources, pollution, land use, and anthropogenic climate change are increasingly causing regime shifts in ecosystems, often to less desirable and degraded conditions. Interdisciplinary discourse on resilience now includes consideration of the interactions of humans and ecosystems via socio-ecological systems, and the need for shift from the maximum sustainable yield paradigm to environmental resource management which aims to build ecological resilience through "resilience analysis, adaptive resource management, and adaptive governance". The concept of resilience in ecological systems was first introduced by the Canadian ecologist C.S. Holling in order to describe the persistence of natural systems in the face of changes in ecosystem variables due to natural or anthropogenic causes. Resilience has been defined in two ways in ecological literature: 1. as the time required for an ecosystem to return to an equilibrium or steady-state following a perturbation (which is also defined as stability by some authors). This definition of resilience is used in other fields such as physics and engineering, and hence has been termed ‘engineering resilience’ by Holling. 2. as "the capacity of a system to absorb disturbance and reorganize while undergoing change so as to still retain essentially the same function, structure, identity, and feedbacks". The second definition has been termed ‘ecological resilience’, and it presumes the existence of multiple stable states or regimes. Some shallow temperate lakes can exist within either clear water regime, which provides many ecosystem services, or a turbid water regime, which provides reduced ecosystem services and can produce toxic algae blooms. The regime or state is dependent upon lake phosphorus cycles, and either regime can be resilient dependent upon the lake's ecology and management. Mulga woodlands of Australia can exist in a grass-rich regime that supports sheep herding, or a shrub-dominated regime of no value for sheep grazing. Regime shifts are driven by the interaction of fire, herbivory, and variable rainfall. Either state can be resilient dependent upon management. Ecologists Brian Walker, C S Holling and others describe four critical aspects of resilience: latitude, resistance, precariousness, and panarchy. The first three can apply both to a whole system or the sub-systems that make it up. 1. Latitude: the maximum amount a system can be changed before losing its ability to recover (before crossing a threshold which, if breached, makes recovery difficult or impossible). 2. Resistance: the ease or difficulty of changing the system; how “resistant” it is to being changed. 3. Precariousness: how close the current state of the system is to a limit or “threshold.”. 4. Panarchy: the degree to which a certain hierarchical level of an ecosystem is influenced by other levels. For example, organisms living in communities that are in isolation from one another may be organized differently from the same type of organism living in a large continuous population, thus the community-level structure is influenced by population-level interactions. Closely linked to resilience is adaptive capacity, which is the property of an ecosystem that describes change in stability landscapes and resilience. Adaptive capacity in socio-ecological systems refers to the ability of humans to deal with change in their environment by observation, learning and altering their interactions.

Donald G. Patterson from EnviroSolutions Consulting Inc speaks at the 8th International Symposium on Recent Advances in POPs Analysis. Since 1990, there has been tremendous progress in understanding human exposure assessment for what to measure, how to measure it, and to do it in a very sensitive and accurate manner. One of the objectives of exposure assessment to environmental chemicals is the quantification of the magnitude, duration, and the frequency and routes of exposure. The main goal is to characterize and enumerate the exposed population.

Roads and other types of linear infrastructure dissect most types of landscapes throughout the world. Road networks are continuing to expand, as new roads are constructed or existing roads are widened to accommodate an increasingly mobile society. The ecological impact of roads and traffic are potentially profound as the road-effect zone (after Forman et al.1997) may extend for many hundreds or thousands of metres either side of the road. Roads can have both positive and negative effects. For example, roads necessarily result in the loss of habitat, can cause the degradation of adjacent habitat and act as a barrier or filter to the movement of fauna. Other effects include noise and light pollution affecting wildlife and air and water-borne chemical pollution affecting plants and aquatic systems. On the positive side, vegetation along roadsides often represent the only native habitat in highly cleared landscapes, and thus may have significance for the conservation of biodiversity and maintenance of landscape processes. The significant challenge for management and conservation is to identify and quantify the extent to which roads and traffic disrupt and modify ecological processes and construct systems that minimise the negative consequences. The extreme cost to build a road in terms of dollars and potential environmental impact demands that we get it right. In this talk I will summarise the effects of linear infrastructure on wildlife species under three broad categories, proposed by Jaeger et al (2005). These are species that: (i) avoid the road surface; (ii) avoid traffic emissions and disturbance (e.g. light, noise, chemical emissions); (iii) avoid vehicles - the ability (or inability) of the animal to move out of the way of oncoming vehicles; and (iv) those that are attracted to the road. The use of these four categories is useful to characterise species responses because it allows us to identify the problem and consider suitable and logical approaches for mitigation. Species that avoid the road typically have low-rates of mortality due to collision with vehicles because they rarely venture onto the road. For these species, barrier effects will be high and wildlife crossing structures may not help because the animals do not approach the road and will never reach the crossing structure. Road avoidance also encompasses the situation where the linear infrastructure is fenced or designed in such a way that it represents a complete barrier to movement. For example, a steep cutting or embankment may be a sufficient deterrence to create a barrier before the road is even reached. Habitat area and quality is reduced when animals avoid habitat adjacent to the road due to traffic emissions or disturbance. The size of this area will increase as traffic volume and/or traffic speed increases. Species that are able to avoid cars are those that are willing to attempt to cross the road and are able to do so without collision. Some species are attracted to the road (e.g. basking by reptiles) or the resources available on the roadside (e.g. carrion or increased grass growth), which, depending on their ability to avoid cars, may result in either negative or positive consequences. Clearly the type and severity of road impacts on wildlife is dependent on the characteristics of the species, the landscape, road design and traffic conditions. The combinations of the different responses will require different types of mitigation. However, there are still significant knowledge gaps that must be filled to achieve successful mitigation and a sustainable road network. These include further study of population processes such as demography, dispersal, spatial patterning and comparing these with contiguous habitats to determine road effects and ultimately assess population viability. A potentially important area of research are interactions and exchanges between road systems and adjacent habitats, including the spatial extent and ecological impacts of the movement of biota, of altered hydrology, flows of sediments and particles, and noise effects. Finally, an understanding of landscape-level effects of road systems, including properties of different network structures and the effects of road density on ecosystem processes, is also required.
