(Beyond Pesticides, October 18, 2011) The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) recently announced the availability of a draft environmental impact statement (EIS) that evaluates the potential environmental effects of deregulating (commercializing) sugar beets genetically engineered (GE) to be resistant to the herbicide glyphosate, commonly referred to as Roundup Ready (RR) sugar beets. APHIS considered three alternatives in the draft EIS: deny the petition seeking a determination of nonregulated status (prohibit commercial planting), make a determination of nonregulated status (allow commercial planting), or extend the partial deregulation of RR sugar beets for the root crop, with mandatory conditions and restrictions. Comments will be accepted until December 13, 2011. APHIS originally deregulated RR sugar beets in 2005. A coalition of environmental groups and organic seed companies, led by the Center for Food Safety, challenged the USDA approval in 2008. It argued that GE sugar beets would contaminate organic and non-GE farmers of related crops, such as table beets and chard, as well as increase pesticide impacts on the environment and worsen the current Roundup-resistant “superweeds” epidemic in U.S. agriculture. In September 2009, Judge Jeffrey S. White in the federal district court in San Francisco agreed, […]

(Beyond Pesticides, September 9, 2011) Despite rising concerns over the side effects of herbicide tolerant, genetically engineered (GE) crops, Dow AgroSciences has recently asked for approval of a new GE soybean variety that will be the first ever to be simultaneously resistant to three different pesticides. The soybean variety, which the company is calling “Enlist,” is designed to compete with Monsanto’s line of “Roundup Ready” crops, which are engineered to be resistant to the company’s glyphosate formulation. The Enlist soybean will be resistant to glyphosate as well as glufosinate and 2,4-D. Antonio Galindez, CEO of Dow AgroSciences, told Reuters that the Enlist system is the company’s “most important project ever.” This is likely due to the company’s ambitious target of taking over Monsanto’s dominance of the GE market in American agriculture. Herbicide tolerant (HT) Roundup Ready crop varieties have become nearly ubiquitous in the corn, cotton, and soybean seed markets. Dow will market the product as a replacement for Roundup Ready soybeans. If farmers are finding that weeds in their fields are not responding to applications of Roundup, Dow will argue, then planting Enlist soybeans will allow them to spray a combination of chemicals in order to eradicate the resistant […]

(Beyond Pesticides, September 2, 2011) The widely used herbicide glyphosate, the active ingredient in Roundup, has been detected in significant levels in rain and rivers in agricultural areas across the Mississippi River watershed, according to two new studies released this month by the U.S. Geological Survey (USGS). The studies’ results raise serious concerns about public exposure and potential environmental damages. Detailed results are available in “Occurrence and fate of the herbicide glyphosate and its degradate aminomethylphosphonic acid in the atmosphere,” published in Environmental Toxicology and Chemistry and in “Fate and transport of glyphosate and aminomethylphosphonic acid in surface waters of agricultural basins,” published online in Pest Management Science. Glyphosate is used in almost all agricultural and urban areas of the United States. The greatest glyphosate use is in the Mississippi River basin, where most applications are for weed control on genetically-modified corn, soybeans and cotton. Overall, agricultural use of glyphosate has increased from less than 11,000 tons in 1992 to more than 88,000 tons in 2007. The two studies conducted by USGS examine glyphosate content in air and water samples in the states of Iowa and Mississippi across two growing seasons. The results show that glyphosate is detected 60-100% of […]

(Beyond Pesticides, August 31, 2011) Widely grown corn plants that Monsanto Co. genetically modified to thwart a voracious bug are falling prey to that very pest in Iowa cornfields, the first time a major Midwest scourge has developed resistance to a genetically modified crop. The discovery raises concerns that the biotech crops are spawning “superbugs” and calls into question EPA’s allowance of so-called plant incorporated protectants (PIPs). Fields planted in Monsanto’s Bt corn in some areas of the Midwest are showing damage from the corn rootworm””the very species targeted by Monsanto’s engineered trait. Iowa State University entomologist Aaron Gassmann, PhD has discovered that western corn rootworms in four Iowa fields have evolved and can resist the pesticide built into Monsanto’s genetically altered corn seeds. The scientist said the cases were isolated, but he did not know how widespread the problem could become. Farmers in Illinois are also seeing severe rootworm damage in fields planted in Monsanto’s Bt corn. In 2010, Monsanto acknowledged that in industrial-agriculture regions of India, where Monsanto’s Bt cotton is a dominant crop, the cotton-attacking bollworm had developed resistance. “These are isolated cases, and it isn’t clear how widespread the problem will become,” said Dr. Gassmann in […]

(Beyond Pesticides, August 10, 2011) A citizen advisory council in Boulder County, Colorado is preparing to decide on whether or not to recommend that genetically modified organisms (GMOs) be banned from county lands. The County’s Croplands Policy Advisory Group will meet on Wednesday, August 10 (agenda packet here) to decide if they want farmers who plant their crops on county land to be able to be able to grow crops that have been genetically modified. With organic farmers around the country worried about potential contamination of their crops with GMO pollen following a number of recent regulatory decisions, the citizen council model may represent a good way for communities to come together and find a solution. Currently, many farmers grow on land owned by the county, and some want to plant GMOs to stay competitive with other farmers around the country. However, some citizens of the county are concerned about the widespread use of GMOs and the increased reliance on agricultural chemicals that usually accompanies them. Organic farmers in the area are also very worried. Recent decisions by the U.S. Department of Agriculture have led to the deregulation of several genetically engineered varieties of common crops, including alfalfa and sugar […]

(Beyond Pesticides, August 4, 2011) At least 21 different species of weeds are found to be resistant to the herbicide glyphosate, commonly sold as Roundup and used across thousands of acres of “RoundUp Ready” genetically engineered (GE) crops, according to a series of studies in the current issue of Weed Science. Palmer amaranth, one of the weeds discussed in the journal, can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Fifty-two counties in the state of Georgia had infestations of glyphosate-resistant Palmer amaranth last year. Studies confirm that the weed, which also competes with soybean, corn, grain sorghum and peanut crops, is also resistant to the herbicide phrithiobac in addition to glyphosate. Over-application and over-reliance by farmers on glyphosate to solve all of their weed problems has led to the proliferation of so-called “super weeds,” which have evolved to survive the treatments through repeated exposure. The most common species which have evolved these traits include pigweed (palmer amaranth), mare’s tail, and ryegrass. The spread of resistance is what has led farmers to increasingly rely on more toxic alternative mixtures, including weed killers like atrazine. There […]

(Beyond Pesticides, July 19, 2011) According to a U.S. Department of Agriculture (USDA) study published in the Journal of Environmental Quality, the volatilization of atrazine and metolachlor, two herbicides known to contaminate surface and ground water, consistently results in herbicide movement off the target site that exceeds nontarget field runoff, varying widely depending upon weather conditions. Linked to endocrine disruption, cancer, developmental effects, and more, increased levels of these hazardous pesticides in the air is cause for concern. When averaged over the two herbicides, loss by volatilization is about 25 times larger than movement from surface runoff, despite low vapor pressures. Agricultural Research Service (ARS) soil scientist Timothy Gish, PhD and ARS micrometeorologist John Prueger, PhD led the investigation, which looks at the field dynamics of these two herbicides commonly used in corn production. Prior to this field study, many experts believed that volatilization was not a contributing factor to water contamination because atrazine and metolachlor had a low vapor pressure. However, the monitoring of both herbicide volatilization and surface runoff at the field-scale over multiple years had never been done. So the team set up a 10-year study in an experimental field in Beltsville that is equipped with remote […]

(Beyond Pesticides, July 8, 2011) The U.S. Department of Agriculture (USDA) has issued a decision stating that it does not consider a new type of genetically engineered (GE) turf grass to be subject to federal regulations. In the decision announced by the USDA’s Animal & Plant Health Inspection Service (APHIS), the agency stated that it does not have the authority to regulate introduction or transportation of the GE grass seed under the provisions of the Plant Protection Act . The grass, developed by Scotts Miracle-Gro Company, has been engineered to be resistant to the herbicide glyphosate, commonly sold as Roundup. Kentucky bluegrass is a popular choice for yards and fields as well as pastures and prairies, and the GE seed is expected to be made available for consumers to plant in their home lawns, potentially making it one of the most widely planted GE crops in the country. USDA’s authority to regulate genetically modified organisms (GMOs) stems from provisions of the Plant Protection Act (relevant regulations can be found at 7 CFR 340) that are designed to ensure that GMOs do not present the potential for new “plant pests.” As the New York Times explains, “Since companies have created most […]

(Beyond Pesticides, June 27, 2011) A study published in the May 2011 edition of the journal Reproductive Toxicology finds pregnant women and their fetuses contaminated with pesticides and metabolites of the herbicide gluphosinate and the Cry1Ab protein of the insecticide based on the bacterium bacillus thuringiensis (Bt), both affiliated with genetically engineered (GE) food. The study, “Maternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada,” also identified the same chemicals, as well as glyphosate metabolites in the bodies of non-pregnant women. The study, conducted by researchers at the University of Sherbrooke Hospital Centre in Quebec, Canada, is intended to pave the way for a new field in reproductive toxicology including nutrition and utero-placental toxicities. Herbicide resistance is the most common genetically modified trait in commercial agriculture. Crops are modified to be able to withstand extremely high doses of glyphosate (Roundup Ready) and gluphosinate (LibertyLink). Current herbicide resistant crops include soy, maize (corn), canola, sugar beet, cotton, with and alfalfa. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. The recently released 2010 Agricultural Chemical Use Report by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service […]

(Beyond Pesticides, June 3, 2011) According to the 2010 Agricultural Chemical Use Report released last week by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service (NASS), use of the herbicide glyphosate, associated with genetically engineered (GE) crops, has dramatically increased over the last several years, while the use of other even more toxic chemicals such as atrazine has not declined. Contrary to common claims from chemical manufacturers and proponents of GE technology that the proliferation of herbicide tolerant GE crops would result in lower pesticide use rates, the data show that overall use of pesticides has remained relatively steady, while glyphosate use has skyrocketed to more than double the amount used just five years ago. The 2010 Agricultural Chemical Use Report shows that, in the states surveyed, 57 million pounds of glyphosate were applied last year on corn fields. Ten years prior, in 2000, this number was only 4.4 million pounds, and in 2005, it was still less than half of current numbers at 23 million pounds. Intense corn growing regions have experienced an even greater increase in glyphosate applications. Glyphosate use in the state of Nebraska increased by more than five times in just seven years, going […]

(Beyond Pesticides, May 19, 2011) Scientists at the University of Sherbrooke in Quebec, Canada found that pesticides associated with genetically engineered (GE) foods are present in maternal, fetal and nonpregnant women’s blood, emphasizing the need for further research into the effects that GE food has on human health. The study, “Maternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada” is published in Reproductive Toxicology. Scientists Aziz Aris and Samuel Leblanc analyzed blood samples for 39 nonpregnant women and 30 pregnant woman and their fetuses in Sherbrooke, an urban area of Eastern Townships of Quebec, Canada. It’s important to note that none of the women in the study had ever worked or lived with a spouse that worked in contact with pesticides. The diet of the women involved in the study is described as “typical of a middle class population of Western industrialized countries.” The Cry1Ab toxin, which is an insecticidal protein produced by the soil bacterium Baccillus thuringiensis (Bt) was detected in 93% of maternal blood samples, 80% of fetal blood samples and 69% of the nonpregnant women’s blood. In genetic engineering, the Cry1Ab protein from Bt is transferred into corn so […]

(Beyond Pesticides, May 6, 2011) On Wednesday this week, the Future of Food conference, organized by The Washington Post, convened at Georgetown University in Washington, DC and featured experts in science, industry, and agriculture discussing ways to reform local, national, and global food systems to work toward justice and sustainability. The keynote speaker for the conference was Prince Charles, Prince of Wales, who has been a longtime advocate for the natural world and for sustainable systems of food production. The event also featured such noted speakers as U.S. Secretary of Agriculture Tom Vilsack, global sustainability advocate Vandana Shiva, nutritionist Marion Nestle, writer Wendell Berry, urban agriculture pioneer Will Allen, organic researcher Fred Kirschenmann, author Eric Schlosser, Stonyfield CEO Gary Hirshberg, and many more. Prince Charles in his speech (text available here, video available here) discussed many of the problems currently facing food production and advocated for a swifter and more direct move toward more sustainable, or “durable,” as he called it, systems. Pointing out the many dangers caused by an industrial farming system that depletes natural resources and impairs biodiversity, he argued that we cannot afford to continue operating under the current system for very much longer before it starts […]

(Beyond Pesticides, April 13, 2010) In response to a petition submitted to the U.S. Environmental Protection Agency (EPA) calling for a ban on the non-medical uses of triclosan, Beyond Pesticides is again urging the agency to halt the use of the antibacterial triclosan in consumer products. Citing recent scientific evidence detailing hormone disruption, impaired fetal development, water and crop contamination, the petitioners state that given the emerging science and the violation of numerous environmental statues by triclosan’s use constitutes placing a ban on the chemical. In comments submitted in support of the petition, Beyond Pesticides state that such a dangerous chemical has no place on the consumer marketplace. “The nonmedical uses of triclosan are frivolous and dangerous, creating serious long-term health problems and environmental hazards associated with its continued use. EPA has a responsibility to ban consumer triclosan use in a marketplace where safer alternatives are available to manage bacteria” said Jay Feldman, executive director of Beyond Pesticides. Triclosan’s impact on the consumer market has been aided by a false public perception that antibacterial products are best to protect and safeguard against potential harmful bacteria. However, research into triclosan’s health and environmental impacts shows triclosan does more harm than good, […]

(Beyond Pesticides, February 24, 2011) After 15 years of commercialization, accumulated Genetically Engineered (GE) crops in the world exceeded 1 billion hectares in 2010. For comparison, 1 billion hectares is roughly equivalent to the vast land area of China, or of the United States. The figures are in this year’s International Service for the Acquisition of Agri-Biotech Applications (ISAAA) report, out this week. Of the four most commonly planted GE crops, a rising percentage of the total of all plantings are GE. In 2010, 81% of all soybeans, 64% of cotton, 29% of corn and 23% of canola globally were from biotech seeds, the ISAAA says. “Growth remains strong, with biotech hectare increasing 14 million hectares — or 10 percent — between 2009 and 2010,” said Clive James, chairman and founder of ISAAA. “That’s the second highest annual hectare growth ever — bringing 2010 global plantings to 148 million hectares.” Unfortunately, the situation does not look brighter for this upcoming year due to the recent decision from U.S. Department of Agriculture (USDA) to allow the U.S. sugar beet industry to continue growing Monsanto’s “Roundup Ready,” GE sugar beets and the recent decision to deregulate GE alfalfa seed, despite the risks […]

(Beyond Pesticides, February 22, 2011) After witnessing a patient’s condition improve upon discontinuing the use of antibacterial products containing the active ingredient triclosan, Gerard Guillory, M.D. of Denver, Colorado believes that several of his patients are experiencing health problems caused by daily exposure to the chemical. Dr. Guillory told local ABC 7 News: Denver Channel that he was treating his patient, Mary Lou Simanovich, for hyperthyroidism and asked her about antibacterial soap, which she had been using for years. After Ms. Simanovich stopped using soaps containing triclosan, both she and Dr. Guillory noticed improvements in her condition and overall health. “I feel better now. That’s all I can say and I think there’s an association,” said Ms. Simanovich to the Denver Channel. Antibacterial agents like triclosan, found in many antibacterial products, are linked to a host of adverse health and environmental effects including hormone disruption, possible impaired fetal development, and water and food contamination. Triclosan is an endocrine disruptor and has been shown to affect male and female reproductive hormones and is also shown to alter thyroid function. “My suspicion is that if it’s damaging the thyroid, it’s probably damaging other organs in the body,” said Dr. Guillory to the […]

(Beyond Pesticides, February 9, 2011) Last Friday the U.S. Department of Agriculture (USDA) announced plans to allow the U.S. sugar beet industry to continue growing Monsanto’s “Roundup Ready,” genetically engineered (GE) sugar beets, despite the incompletion of an environmental impact statement (EIS). This comes one week after USDA decided to fully deregulate GE alfalfa seed, despite the risks it poses to both organic and conventional farmers. On Monday, Center for Food Safety, Beyond Pesticides, Sierra Club and Cornucopia Institute formally filed a 60-day notice of intent to sue the agency concerning its decision to allow unrestricted deregulation of GE alfalfa. The 60-day notice of intent to sue, filed February 7, 2011, officially notifies USDA’s Animal and Plant Health Inspection Service (APHIS) of the groups’ intent to sue pursuant to the citizen suit provision of the Endangered Species Act (ESA), citing APHIS’ violation of Section 7 of the ESA in failing to ensure that the deregulation of GE alfalfa is not likely to jeopardize threatened or endangered species and their habitat. According to Section 7, APHIS must consult with the U.S. Fish and Wildlife Service (FWS) to ensure that agency actions do not impact threatened or endangered species. The notice charges […]

(Beyond Pesticides, January 3, 2011) The United Nations Food and Agriculture Organization (FAO) has announced the initial results of an experimental program in West Africa that reduces farmers’ use of pesticides and chemical inputs while increasing yields and income. The program, entitled the West African Regional Integrated Production and Pest Management Program, evaluated the use of ecological management versus conventional practices on vegetables, cotton, and grain crops in the countries of Benin, Burkina Faso, Mali, and Senegal. The evaluation shows dramatic decreases in pesticide usage, reduced environmental degradation, as well as increases in farmer income through higher yields and reduced inputs. According to the FAO (which previously advocated for organic agriculture), the goals of the program, which is ongoing, are “building local farming capacity, improving food security and livelihoods, and raising awareness of negative externalities and positive alternatives.” These are accomplished through training farmers in what the FAO calls integrated production and pest management (IPPM) methods so that they can reduce toxic inputs and pollution while enhancing soil fertility and retaining more of their income. The particular methods of IPPM include reducing pesticide usage, soil building through incorporation of compost and manure and the planting of cover crops, careful monitoring […]

(Beyond Pesticides, December 14, 2010) A petition of more than a million signatures was presented to the European Commission last week, demanding a halt to approvals of new genetically modified (GM) crops and the establishment of up a new scientific body to study the impact of the technology and determine regulations. Greenpeace led the effort. The petition is seen as a test case for the “European citizen’s initiative,” introduced under the European Union’s new constitutional treaty, which enables a million or more people to jointly ask the European Commission to change EU legislation. It follows the Commission’s decision in March to grant the first EU GM cultivation approval in 12 years for the “Amflora” potato. “Over a million people across Europe have set the EU a democratic test — will the EU address the real concern people have about GM crops and food, or will it side with the chemical industry lobbyists controlling GM technology?” Greenpeace’s EU Director Jorgo Riss said. “Until safety issues of GMs are examined by independent experts, all GM authorizations should stop.” A spokesman for the EU executive said it would treat the signatures “as a petition in the spirit of the citizen’s initiative,” Despite the […]

(Beyond Pesticides, November 17, 2010) Researchers with the U.S. Geological Survey (USGS) have found a dozen agricultural fungicides in the waters and sediments downstream of farms and orchards in western states. Presented November 8, 2010 at the annual meeting of the Society of Environmental Toxicology and Chemistry (SETAC) in Portland, Oregon, the findings represent the first such data on fungicides in the western U.S. Farmers routinely use fungus-killing compounds to spray or dust food crops, such as strawberries, corn, and soybeans. Some crops receive up to a dozen doses per growing season. Nationwide, fungicide use has risen considerably since the 1990s, reaching 350 million pounds in 2001. However, the environmental prevalence and effects on wildlife and ecosystems, particularly of newer fungicides, are poorly understood, says Kathryn Kuivila, PhD, of the USGS California Water Science Center. Environmental monitoring programs monitor concentrations of few or no fungicides, she notes. The study entitled, “Occurrence of Azoxystrobin, Propiconazole, and Selected Other Fungicides in US Streams, 2005—2006,” documents the occurrence of fungicides in select U.S. streams soon after the first documentation of soybean rust in the U.S. and prior to the corresponding increase in fungicide use to treat this problem. Water samples were collected from […]

(Beyond Pesticides, November 9, 2010) In October, 11 groups representing chemical-intensive and biotech-based agricultural interests dropped out of the process to develop an American National Standards Institution (ANSI)-certified standard for sustainable agriculture, facilitated by the Leonardo Academy. The groups cited committee dominance “by environmental groups, certification consultants, agro-ecology and organic farming proponents” and an opposition to “modern agriculture” as their main reasons for resigning. The drop-outs include the American Farm Bureau Federation, American Frozen Food Institute, American Soybean Association, California Seed Association, CropLife America, Environmental Intelligence, Inc., Grocery Manufacturers Association, National Corn Growers Association, National Cotton Council of America, and United Fresh Produce Association. “These groups relentlessly pushed for molding the standard to validate industrial agriculture and high tech genetic manipulation,” says Jeff Moyer, Farm Director at the Rodale Institute and active member of the committee. “The model they propose confuses short-term profits for sustainability.” Responding to the resignation, a Leonardo Academy spokesperson said it, “recognizes their perspective but disagrees with their assessment.” The Academy believes their ANSI-approved standard development process provides the balance across interest categories needed for developing a Sustainable Agriculture Standard that will be widely implemented and successful in the marketplace. They state that the balance is […]

(Beyond Pesticides, October 18, 2010) Despite condemnation from environmentalists and human rights advocates, the business practices employed by biotech giant Monsanto seemed to be serving the St. Louis-based company well, until this year where disappointing sales, increased competition and even a federal investigation have sent stock prices into a downward spiral. Monsanto’s Roundup Ready corn, soy, and other crops have been engineered to resist the broad spectrum herbicide glyphosate, sold by Monsanto under the trade name Roundup. Monsanto holds the patent for its Roundup Ready seeds, meaning farmers must sign a contract with the company in order to purchase seeds, and are not allowed to save seeds to plant the following season. As seen in the recent documentary Food Inc., Monsanto has been ruthless in collecting royalties from growers. Despite Monsanto’s safety claims, glyphosate is actually very dangerous to human health and the environment. Glyphosate has been linked to cancers including non-Hodgkin’s lymphoma. Acute exposure can lead to swelling of the eyes, face and joints; burning or itching, blisters rapid heart rate, chest pains and other symptoms. The California Department of Pesticide Regulation has found glyphosate to be the most common cause of pesticide-induced illness or injury. Glyphosate is also […]

(Beyond Pesticides, September 29, 2010) A class action complaint claims Dial Corp. defrauds consumers about its Dial Complete soap by falsely claiming that it ‘kills 99.99% of germs,’ when in fact the product provides no benefit over washing with regular soap and water. The suit states that Dial Corp.’s claims are deceptive and misleading, designed solely to cause consumers to buy the product. Dial Complete contains triclosan, a registered pesticide, which is linked to numerous adverse effects including hormone disruption and water contamination. The suit wants Dial Corp. enjoined from continuing its deceptive advertising, disgorgement and damages for consumer fraud and deceptive business practices. The plaintiff, David Walls, in his suit states there are no reliable studies that show Dial Complete lives up to these claims. His complaint states: “Through its extensive and comprehensive nationwide marketing campaign, defendant claims that Dial Complete ‘kills 99.99% of germs’, is the ‘#1 Doctor Recommended’ brand of antibacterial liquid hand wash and ‘kills more germs than any other liquid hand soap’, when in actuality, it does not, a fact which Dial knew and purposely misrepresented and failed to disclose to consumers. To this day, Dial has taken no meaningful steps to clear up consumer […]

(Beyond Pesticides, September 23, 2010) A study by U.S. Department of Agriculture (USDA) scientists and cooperators provides new details about how fertilizing soils with biosolids also introduces triclosan, an antibacterial agent in soaps and other cleaning supplies, into the environment. Results show that triclosan in biosolids is only slowly degraded and persists at low levels in the environment for long periods of time. Biosolids are illegal for use in organic agriculture. For this study, entitled “Fate of triclosan in agricultural soils after biosolid applications” and published in Chemosphere, Agricultural Research Service (ARS), chemist Clifford Rice, of the ARS Environmental Management and Byproduct Utilization Laboratory in Beltsville, Md., and his partners determined that triclosan levels in Class B biosolids from a Mid-Atlantic wastewater treatment plant averaged around 15.5 milligrams per kilogram. They collected surface soil samples from 26 farms in northern Virginia, mostly from pastures. Some fields had never been amended with biosolids and others had been amended with one to four applications of biosolids within the previous 9 months to 13 years. Most of the biosolid amendments came from the wastewater treatment plant in the study. Generally, conventional chemical-intensive farmers add “Class B” biosolids, also known as treated wastewater solids, […]
