  • Manure from millions of hogs fuels natural gas project

    One recipe for renewable natural gas goes: Place manure from about 2 million hogs in lagoons, cover them with an impermeable material and let it bake until gas from the manure rises. Then, use special equipment to clean the gas of its impurities and ship the finished product out. That's the vision of one of the largest biogas projects of its kind in the U.S. currently being installed in northern ...

  • 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 ...

  • 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 ...

  • Company scrambled by egg-traordinary fine

    One of the largest egg producers in the UK has been ordered to pay £65,000, as well as costs of £9,500, for operating five sites across England without the required environmental permits. Lincolnshire company, L J Fairburn, ran the sites between 1 February 2007 to 17 February 2012 without authorisation. Skegness Magistrates’ Court heard that at one time, Back Lane Poultry ...

  • Bio-QZ processes cow manure for anaerobic digestion

    The community of Sand in Taufers in the Italian South Tyrol has set itself the target of eliminating the CO2 emissions of its population. A decisive role in achieving that aim plays a AD plant on cooperative basis. The used cow dung as substrate is pre-treated by the MeWa QZ. Sand in Taufers and its 5,300 inhabitants are forging ambitious plans. Local government and citizens are ...

  • 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 ...

  • Muckbuster Changes Runoff from Problem to Profit

    Free-range pig farms near coastal regions are an example of a farming practice, which has resulted in a change in the local ecosystem, which can be dangerous to humans. When the slurry from free-range pig farms is not contained and moves into the streams, which empty into the rivers, and finish in the sea, the enormous increase in nutrients in the water creates a huge population of seaweed, and ...

  • Comparing N2O emissions from organic and mineral fertilisers

    A recent study compares the effects of organic, 'natural' fertilisers, such as compost, with mineral, synthetic fertilisers, such as urea, on N2O emissions from Mediterranean soil. It suggests that there is little difference between the fertilisers, but that pig slurry offers the best overall balance in terms of emissions and crop yield. Nitrous oxide (N2O) is a powerful greenhouse gas (GHG). ...

  • Microbe diet key to carbon dioxide release

    As microbes in the soil break down fallen plant matter, a diet 'balanced' in nutrients appears to help control soil fertility and the normal release of the greenhouse gas carbon dioxide into the atmosphere. When plants drop their leaves, stems and twigs, this organic matter slowly becomes part of the soil as a result of decomposition, which is facilitated by bacteria and other microbes. This ...

  • 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 ...

  • NFU demands action over nitrate vulnerable zone (NVZ) proposals

    Defra (the UK's Department for Environment, Food and Rural Affairs) must make substantial alterations to its proposals to change Nitrate Vulnerable Zones before any action is taken to implement them, the National Farmers' Union warns. The NFU has submitted a list of 45 recommendations for alterations as part of its submission on the proposals, which it estimates will cost farmers hundreds of ...
