manure ammonia News

  • New strategy aims to reduce agricultural ammonia

    As concerns about air pollution from large dairies and other concentrated animal feeding operations (CAFOs) continue to mount, scientists are reporting a practice that could cut emissions of an exceptionally abundant agricultural gas—ammonia—by up to 30%. In the May-June 2011 issue of the Journal of Environmental Quality, a team led by Mark Powell, a soil scientist with the USDA ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Toyota Launches Swine Manure Compost Deodorizer

    Toyota City, June 20, 2011 - (JCN Newswire) - Toyota Motor Corporation (TMC) has developed a deodorizer specifically for use on composting swine manure. Toyota Roof Garden Co., Ltd., a TMC subsidiary, is manufacturing and distributing the product for its "resQ45" series of manure composting systems. Sales, starting today, are being conducted through the fertilizer sales routes of Toyota Tsusho ...

  • 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 ...

  • Using Liquid Manure to Fertilize Wheat? Consider Timing, Nitrogen Content

    Liquid livestock manure can be a great option as a spring top-dress fertilizer for wheat fields if applied during the appropriate window of time and if it has the right amount of nitrogen, according to research conducted by the College of Food, Agricultural, and Environmental Sciences at The Ohio State University. In a report published in the latest issue of the college’s  ...

  • 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 ...

  • 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 ...

  • Ductor is opening a groundbreaking biotech plant in Haren, Germany

    Ductor Corporation is announcing today that it will reach the goal of implementing its first commercial fermentation technology in Germany this autumn. The first implementation will be an application for the biogas producer in order to significantly improve the economics of a biogas plant via replacing the expensive maize silage with inexpensive poultry manure. As of September 2016, this biogas ...

  • 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 ...

  • Revolutionary technology by Ductor commissioned in Tuorla, Finland

    The first biogas plant equipped with Ductor’s nitrogen and phosphorus recovery technology was put into use in Tuorla late November 2016. The size of the Ductor fermenter at the demonstration plant is 80 m3, and with Ductor’s process the plant is capable of treating 1,400 tons of poultry manure each year, producing 266,000 m3 of biogas, 115 tons of ammonium sulfate, and 640 tons of ...

  • 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 ...

  • Utilisation of nitrogen and phosphate on dairy farms could be increased

    Nitrogen and phosphate are important fertilisers. But excessive amounts often found in fields and pastures end up polluting the ground and surface water. Furthermore, dairy farmers are squandering their profits by wasting these expensive fertilisers. The Koeien & Kansen [Cattle and Opportunities] project set up by two PhD candidates from Wageningen University, part of Wageningen UR, shows how ...

  • Company scrambled by egg-traordinary fine

  • 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 ...
