  • 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 ...

  • New Material to Enhance Soils using Manure Waste

    The results of the research group of Valuation of resources from Universidad Politécnica de Madrid suggest an optimal solution to manage the manure from chicken and cattle. Biochar, a material obtained after thermal treatment of this waste through pyrolysis, is an organic fertilizer that applied in ...

  • Treating animal manure with borax cuts odor

    Hydrogen sulfide is one of the compounds contributing to the stink from manure storage pits on hog farms. Microbial activity in the manure releases the hydrogen sulfide and other compounds. Today, at an American Society of Microbiology meeting in Boston, Mass., Agricultural Research Service (ARS) scientist Cheryl Spence reports the results of a study in which 'dusting' hog manure with borax ...

  • Effects of chemical fertiliser and animal manure on soil health compared

    Fertilising crops with cattle manure can lead to better soil quality than when synthetic fertiliser is used, recent research indicates. The use of cattle manure in the study led to greater soil fertility by encouraging higher microbial activity, and the researchers suggest that it could potentially improve soil’s ability to cope with periods of difficult growing conditions. The ...

  • Humification and degradability evaluation during composting of horse manure and biowaste

    Performing compost quality assessment such as compost stability is quite necessary for rating the quality of horse manure and biowaste composts and meeting specific regulatory requirements on the composition and compost process. The aim of this study was to identify an appropriate feedstock composition for use in the production of high quality compost. The objectives were to (1) identify an ...

  • 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 ...

  • Manure matters! How can you turn poultry manure into value? Poul-AR produces fertilizer and sustainable energy from poultry waste

    Colsen has developed a new technology to valorize poultry manure. Until now poultry manure is considered a waste stream with a considerable cost, Poul-AR® now represents an important valorization step, by which the manure will generate nutrients and energy. This is directly associated with considerable operational benefits and thus represents a large added value ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Oil spray reduces greenhouse gas emissions from pig finishing barns

    Animal feeding operations are an important emission source of air pollutants including methane and carbon dioxide—known greenhouse gases. Recent inventories suggest that animal manure makes a significant contribution to global methane emissions. As a consequence, greenhouse gas emissions can potentially become a limiting factor in the development and sustainability of animal production and ...

  • 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 ...

  • Household compost as good for soil as conventional fertilisers, say EU researchers

    Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

  • New rules for English farmers to prevent nitrate pollution

  • 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 ...
