manure emissions News

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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). ...

  • Farmers could cut emissions while boosting production

    Farmers could earn more and protect the environment by using technologies and practices that reduce the global warming gases that livestock emit, according to a report by the UN Food ...

  • Agricultural ammonia emissions could be reduced without affecting crop yield

    Ammonia released by nitrogen fertilisers in Spanish agriculture could be reduced by up to 82% with only a very minimal impact on crop yield, finds new research. This could be achieved by combining optimised management of manure with the use of non-urea synthetic fertilisers. Agriculture accounted for almost 94% of total European atmospheric emissions of ammonia in 2011. The main sources of these ...

  • 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 ...

  • Major cuts of greenhouse gas emissions from livestock within reach

    Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies, according to a new study released today by the UN Food and Agriculture Organization (FAO). The report, Tackling climate change through livestock: A ...

  • Emissions data from animal feeding operations study now available / EPA also solicits additional information to further understand emissions (HQ)

    The U.S. Environmental Protection Agency is making data publicly available from a two-year study of air emissions from animal feeding operations (AFOs). AFOs, which house large numbers of animals for production of meat, dairy products and eggs, were monitored for the following air pollutants: ammonia, hydrogen sulfide, particulate matter and volatile organic compounds. The data available today ...

  • 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 ...

  • Managing carbon loss

    As the United States continues to develop alternative energy methods and push towards energy independence, cellulosic-based ethanol has emerged as one of the most commercially viable technologies. Corn stover remains the most popular source available, but the loss of soil organic carbon (SOC) associated with the removal of corn fodder as a cellulosic ethanol feedstock is of agricultural and ...

  • 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 ...

  • Environmental impacts of dairy farming in the Czech Republic

    New research suggests that dairy farming may have an important impact on the environment and human health. Although differences in the impact of farming practices across countries have been known for some time, this is the first study to explore the impact of the dairy industry in different regions in the Czech Republic. Dairy farming in the Czech Republic is commonly large-scale with 500 or more ...

  • New initiative will reduce air pollution from agriculture

    Ammonia emissions into the air is a major threat to human health, causing cardiovascular and respiratory diseases. Atmospheric ammonia is also a significant source of acidification and excess nutrient loading, causing loss of biodiversity in many of the most vulnerable ecosystems. This calls for stronger action to reduce emissions. Ammonia or NH3 mainly comes from manure produced by ...

  • Soil and crop management and carbon sequestration

    Research results from management scenarios ranging from those in the South Eastern, Great Plains, and Upper Midwest regions of the US and from Italy are reported in the March-April, 2010 issue of the Soil Science Society America Journal. This group of papers originated from the Soil Carbon Sequestration and Greenhouse Gas Mitigation Symposium that was held jointly by the Soil Science Society of ...

  • Sizing up livestock farming’s carbon footprint

    A new and interactive tool released by FAO allows farmers, policy makers and scientists to calculate meat, milk and eggs production as well as greenhouse-gas emissions from livestock to make the sector more productive and more climate-friendly.   GLEAM-i, the Global Livestock Environmental Assessment Modelinteractive, provides answers to a ...

  • Fossil fuels and meat consumption pollute coasts

    Eutrophication: Sources and Drivers of Nutrient Pollution, the second report of a three-part series, finds that developing countries will see more nitrogen and phosphorus pollution in coastal and freshwater areas in the coming decades as a result of population and economic growth. More people and rising incomes will increase the demand for food, energy, land and other natural resources, which ...

  • Can Livestock Help Reduce Greenhouse Gases?

    Wider use of best practices and technologies could significantly reduce greenhouse gas emissions in the livestock industry, according to a recent United Nations Food and Agriculture Organization report. The 139-page report, “Tackling climate change through livestock: A global assessment of emissions and mitigation opportunities,” is ...
