  • 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 ...

  • Manure runoff depends on soil texture

    Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing ...

  • 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 ...

  • Southern soils mitigate manure microbes

    That swine manure sprayed on to fields adds valuable nutrients to the soil is well known. But what is not known is whether all that manure is bringing harmful bacteria with it. A new study looks at the levels of nutrients and bacteria in soils of fields that have been sprayed with manure for fifteen years or more. The research team, composed of scientists from the USDA-ARS Crop Science Research ...

  • A new tool to assess nitrogen and phosphorus flow in agriculture

    MITERRA-EUROPE is a new tool that models the amount of nitrogen and phosphorus, among other key pollutants, used in agriculture across all 27 Member States at regional, country and EU-27 levels. It can be used to calculate the effects of different strategies to minimise excess pollution.  Many regions in the EU-27 use more nitrogen and phosphorus in agriculture than is required. The main sources ...

  • Understanding phosphorus in soils is vital to proper management

    Phosphorus is one of the key nutrients that can cause algal blooms and related water quality problems in lakes, rivers, and estuaries worldwide.  Phosphorus entering waters originates from a variety of sources.  Agricultural land receiving long term applications of organic by-products such as animal manure is one of the major contributors.  Such soils often become enriched with P, leading to ...

  • Improve crop yield by removing manure solids

    Manure has long been used as a crop fertilizer, but the challenge of finding an efficient use of the nutrients found in manure is ever present. The ratio of nitrogen to phosphorus in manure is low in relation to the nutrient needs of most crops. Therefore, crops tend to be overloaded with manure to meet the nitrogen requirement of agricultural crops, but the excess phosphorus from the process can ...

  • Study probes sources of Mississippi river phosphorus

    In their eagerness to cut nitrogen and phosphorus pollution in the Mississippi River and Gulf of Mexico, people have often sought simple explanations for the problem: too many large animal operations, for instance, or farmers who apply too much fertilizer, which then flows into waterways. But according to new modeling research that examined phosphorus loading from all 1768 counties in the ...

  • Manure `smells like money` as energy costs rise

    With energy prices driving the cost of agricultural inputs up, nutrient-rich manure is getting another look. 'Calls to Extension offices from people looking for manure and manure compost have increased in recent months,' says Tommy Bass, Montana State University Extension livestock environment associate specialist. Bass said that this shift in perception is good for water quality, too. 'As manure ...

  • LWR manure treatment system goes solar

    Solar energy is now making it easier for farms to implement the manure treatment technology that is revolutionizing the livestock industry. Livestock Water Recycling's Innovation Centre has just released the latest advancement in manure treatment technology which allows farmers the ability to power their LWR Manure Treatment System by solar energy. "Farmers inherently want to leave the world ...

  • Sustainable phosphorus use — evaluating past patterns to inform future management

    Recycling waste from farming and mining could help improve the sustainable use of phosphorus, a recent study suggests. The study traced the stocks and flows of phosphorus over a 50 year period to reveal changing patterns of global phosphorus use. The results can be used to develop the sustainable management of phosphorus — a finite and critical resource — in the future. ...

  • Manure Event to Show New Ways to Boost Both Crops and Water Quality

    Manure has two shades of green, so to speak. The green of greater farm crop yields. And the green of a cleaner environment. Organizers of the Aug. 14 Manure Science Review say farmers can see both at the same time and that the event will show how to do it. “Manure is an excellent product for improving soil ...

  • 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 ...

  • Compost made by worms from livestock manure yields benefits when applied to maize

    Vermicomposting livestock manure with maize can increase agricultural benefit by 304%, shows a new study. The combination of increased crop yield and the additional earthworms produced as a result of the process led to a substantial increase in output compared to a traditional composting system. As intensive agriculture and livestock production both increase, unique problems emerge. Heavy use of ...

  • Manure Science Review Slated Aug. 12: How to Maximize Crop Benefits, Minimize Water Risks

    Manure Science Review this year will have a clear focus on water. The annual learning event will present more than a dozen sessions on getting the most from the nutrients in manure while limiting the chance of them reaching lakes and streams. It’s for farmers and others in the industry. “Manure is an excellent soil amendment and provides nutrients for crop growth,” said  ...

  • Target the crop not the soil - to reduce fertiliser use

    Feed the crop not the soil’ is the message of a new review into sustainable phosphorus use. Currently, phosphorus fertiliser is applied to the soil, and plants then take it up through the roots. However, more precise nutrient management is needed on farms, the researchers say, so that the phosphorus is targeted at the crop just as it needs it. Modern agriculture is dependent on phosphorus, ...

  • Proposed rule for farms aims to improve Lake Erie

    Ohio's lawmakers are taking their first step toward slowing the spread of algae in Lake Erie since a toxin contaminated the drinking water for more than 400,000 people. Legislation approved in the state House would ban farmers in much of northwestern Ohio from spreading manure on top of frozen or saturated fields. Another provision would set new rules on dumping dredged sediment in the lake. Both ...

  • American society of agronomy

    Recycling manure is an important practice, especially for large livestock producers. Manure can be used as fertilizer to aid in crop production, aiding livestock producers that grow their own feed crops. While manure does provide a rich nutrient source for crops, it also can contribute to nutrient leaching and runoff. This can contaminate the surrounding ecosystem and lead to eutrophication of ...

  • EPA orders Illinois livestock operation to pay $40,000 penalty for unauthorized waste discharges (IL)

    U.S. Environmental Protection Agency Region 5 has ordered Greenville Livestock Inc., 25815 Hugo Road, Centralia, Ill., to pay a $40,000 fine for failing to comply with the Clean Water Act. EPA previously ordered the facility to stop all unauthorized discharges and apply to the Illinois Environmental Protection Agency for a permit to discharge wastewater. Greenville is a large concentrated animal ...

  • New Poultry Litter Applicator Can Cut Nutrient Runoff, Protect Water Quality
