  • Tracking phosphorus runoff from livestock manure

    Nutrient runoff from livestock manure is a common source of agricultural pollution. Looking for an uncommon solution, a team of scientists has developed an application of rare earth elements to control and track runoff phosphorus from soils receiving livestock manure. In addition to reducing the solubility of phosphorus, this method shows particular promise for researchers interested in tracking ...

  • Rainfall and manure application timing affect organic carbon losses

    Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural landscape. Specific land management practices, such as manure application, can play a large role in the export of DOC as soluble organic carbon is applied to or injected into ...

  • Bernardin Lochmueller Awarded Patent for CAFO Wastewater Treatment Wetlands

  • Pew Commission calls for better US animal waste treatment

    One step beyond her front door, Jayne Clampitt is greeted with the toxic fumes flowing from the roughly 1 million gallons of hog manure stored at her neighbor's farm. She no longer dries her family's laundry outside, her children avoid the nearby polluted stream, and she worries that their shallow drinking well will also be contaminated with toxins. 'We thought there was this unspoken connection ...

  • Soil phosphorus in an organic cropping system

    Phosphorus is a nonrenewable resource, raising concerns that agricultural practices may deplete reserves. (For one overview discussion of phosphorus, see Phosphorus Famine: The Threat to Our Food Supply in the June 2009 Scientific American.) Organic farming with low phosphorus  inputs can result in deficient levels of plant-available phosphorus (available-P).A group of researchers from ...

  • Using rotation crops to improve soil quality

    Soil quality issues are being researched within two crop rotation experiments that started in 1994 at Narrabri. They compare several crop rotations that include or exclude legume phases. The data presented here relate to the most recent 2-year cycles of these experiments. Following cotton harvest at the end of the previous cycle, rotation crops are sown (winter cereal, faba beans (grain) or vetch ...

  • LiqTech International, Inc. Announces A New Product To Its Portfolio, SiC Membrane Discs

    LiqTech International, Inc. (OTCQX: LIQT) ("LiqTech") is pleased to announce the newest product to the Company's portfolio, SiC membrane discs. The membrane disc system is based on a principle of creating cross-flow by rotating the membrane as an alternative to pumping the liquid across the membrane in the traditional tubular setup. Energy consumption is only 17% compared to regular cross-flow. ...

  • California agencies seek dairy digester projects – Proposals due November 1

    The California Department of Food and Agriculture, the U.S. Environmental Protection Agency and their partner agencies in the California/Federal Dairy Digester Working Group have announced a joint solicitation for dairy digester concept proposals. California is the largest dairy state in the USA, with approximately 1.7 million cows producing more than 3.6 million dry tons of manure per year that ...

  • Skagit county’s samish bay shellfish beds deserve better protection, say federal, state and county officials

    Skagit County’s Samish watershed will come under closer scrutiny by federal, state and county environmental inspectors as they pursue cleaner water and safer shellfish in Puget Sound’s Samish Bay. The boost in protection includes coordinated inspections in the Samish Watershed and a $960,000 U.S. Environmental Protection Agency grant to Skagit County to locate, identify and remedy ...

  • Nitrogen recommendations based on crop reflectance

    Nitrogen fertilizer is usually applied in greater quantities to corn than almost any other crop. But when it’s applied in excess of requirements, loss of the excess fertilizer to the environment can contribute to degraded water quality. One of the challenges to making an appropriate nitrogen fertilizer recommendation is the potential variability in soil nitrogen availability that may occur ...

  • Bion Announces Kreider Farms Phase 2 Poultry Credit Protocols Submitted to Pennsylvania Department of Environmental Protection

    NEW YORK - Bion Environmental Technologies, Inc. (OTC Bulletin Board: BNET) announced today it has submitted its nutrient credit trading application for Phase 2 of its Kreider Farms (KF) project to the Pennsylvania (PA) Department of Environmental Protection (DEP).  This application, upon approval by the DEP, will project the number of certified nitrogen and phosphorus credits eligible to be ...

  • How can we use phosphorus more efficiently and create opportunities for recycling?

    The Commission is launching a consultation on how to use phosphorus in a more sustainable way. Phosphorus is widely used in agriculture and is an essential component in fertiliser and animal feed, but it is a resource which has no substitute. Supplies are limited, prices have been volatile and much phosphorus is currently wasted, creating concerns about the cost and availability of future ...

  • USPOULTRY’s Live Production and Welfare Seminar Highlighted Animal Welfare Practices and New Equipment Technology

    “Whenever birds are handled for any reason, including vaccinations, treatments and movement to new facilities or to processing, handling should be accomplished in such a manner as to avoid injuries. Abuse of the animals is not tolerated under any circumstances,” stressed Dr. Sam Christenberry, poultry technical services manager, Phibro Animal Health, while addressing attendees at ...

  • Nutrient levels on the decline in many Estonian rivers

    A new study has analysed the impact of industrial and agricultural changes on nutrients in Estonian rivers. The results indicated that there were significant reductions in nitrogen in one third of the sites, significant reductions in phosphorus in a quarter of sites and significant reductions in both nutrients in nearly a tenth of sites. High levels of nutrients, such as nitrogen and phosphorus, ...

  • Environmental impact of animal waste

    North and South Carolina have seen a steady increase in swine production over the last 15 years. In North Carolina alone, swine production generates approximately a quarter of the state’s gross farm receipts. The presence of so many large-scale pig farms leads to the problem of proper animal waste disposal.   The most common practice in the Carolinas is storing animal waste in ...
