  • 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 ...

  • Scientists help farmers create greener dairies

    Cows stand patiently in a tent-like chamber at a research farm in western Wisconsin, waiting for their breath to be tested. Outside, corrals have been set up with equipment to measure gas wafting from the ground. A nearby corn field contains tools that allow researchers to assess the effects of manure spread as fertilizer. Scientists based at the University of Wisconsin-Madison have started a ...

  • 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 ...

  • 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 ...

  • Innovative technology helps dairy-giant in Swedish idyll

    Three or four years of waiting for an expansion of the capacity at the municipal sewage treatment plant in Vimmerby, Sweden, made Arla choose a much faster alternative. Now, Grundfos BioBooster cleanses the waste water so efficiently that it can be discharged into the idyllic landscape close to Astrid Lindgren’s native town. The surroundings from Astrid Lindgren’s marvellous ...

  • 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 ...

  • 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 ...

  • Goat farmers, producers handle increased demand for dairy

    Buying two goats in August 2008 was little more than an experiment for farmer Paula Olson and some entertainment for her daughters. Six and a half years, 14 milking goats and roughly $300,000 later, she's in the midst of constructing a small-scale creamery in Madrid, Iowa, that's set to feature goat milk, cheese, ice cream and more. And though her creamery isn't yet open, Olson said local ...

During that inspection, EPA and Oregon Department of Agriculture field personnel determined that animal waste had been ...

  • Dairy farmers of America and Vanguard renewables announce strategic alliance

    Dairy Farmers of America (DFA), a national farmer-owned dairy cooperative, and Vanguard Renewables, a Massachusetts-based renewable energy developer, announce a strategic partnership to help bring anaerobic digestion technology to more farms across the country.  While waste management and environmental sustainability are top priorities for dairy farmers today, renewable energy methods, like ...

  • New tool opens world of climate finance to dairy sector

    The dairy sector will soon be able to participate in international carbon credit markets thanks to a new methodology that lets farmers and project designers reliably document how they are reducing harmful greenhouse gas emissions - a step that will open up new sources of finance for the livestock industry and help promote investment in smallholder operations. FAO's new  ...

  • Milk Cliff Averted, iPhones Step in for Manure Management Regulatory Cleanup

  • 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  ...

  • Reduced phosphate excretion by dairy cattle by cutting at a later stage

    The phosphorus content in grass is lower if the grass is cut at a later stage. This also means that the phosphate excretion of a dairy herd is reduced and farms that use BEX benefit from cutting later. But the energy and protein content of the grass is also less. In order to keep milk production at the same level, approx. 250 kg more concentrates are required per cow. Cutting at a later stage ...
