  • Rainfall and manure application timing affect organic carbon losses

    Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural landscape. Specific land management practices, such as manure application, can play a large role in the export of DOC as soluble organic carbon is applied to or injected into ...

  • 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 ...

  • 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 ...

  • 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  ...

  • 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 ...

  • GWT Series Natural Zeolite Media Agricultural Applications

    Zeolite based fertilizers are known to be "smart fertilizers" due to the high cation exchange capacity (CEC) and porous crystalline structure. Zeolite is the only negatively-charged mineral in existence in the world, for these purposes it has therefore has significant uses across a wide range of applications and in particular in Agriculture applications. Zeolite has a known ability to act as a ...

  • 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 ...

  • Study of agricultural watersheds and carbon losses

    Dissolved organic carbon (DOC) losses from tile drains are an underquantified portion of the terrestrial carbon cycle. This is particularly important in the eastern corn belt where tile drainage dominates the agricultural landscape. Specific land management practices, such as manure application, can play a large role in the export of DOC as soluble organic carbon is applied to or injected into ...

  • Nutrient Management Plans: A Study in Cause and Effect

    It seems practical on the surface. Nutrient management plans (NMPs) should supply plants with ideal amounts of nutrients, minimize runoff, and maintain or even improve the soil condition. And the farmer behind the plan would work with a set of conservation practices designed to reduce harmful pollutants while still obtaining optimal crop yields. However, many U.S. Animal Feeding Operations (AFOs) ...

  • 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 ...

  • LiqTech International, Inc. Announces A New Product To Its Portfolio, SiC Membrane Discs

    LiqTech International, Inc. (OTCQX: LIQT) ("LiqTech") is pleased to announce the newest product to the Company's portfolio, SiC membrane discs. The membrane disc system is based on a principle of creating cross-flow by rotating the membrane as an alternative to pumping the liquid across the membrane in the traditional tubular setup. Energy consumption is only 17% compared to regular cross-flow. ...

  • 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 ...

  • Household compost as good for soil as conventional fertilisers, say EU researchers

    Since 2005, conventional disposal of organic waste has been prohibited in Sweden. Instead, this waste is incinerated or separated at source, processed (composted or anaerobically digested) and recycled as fertiliser on crop land. A new study has investigated the use of organic waste from different sources as a fertiliser and found that residue from biogas production is an effective fertiliser. ...

  • New software helps farmers manage nutrients

    University of Missouri Extension has released a new Web-based application to help farmers manage soil nutrient needs on farms. Nutrient management helps farmers set rates and timing of fertilizer applications, said John Lory, MU Extension nutrient management specialist. Plans are required for some farms in cost-share programs and permitted animal feeding operations. The free MMPTracker tool is ...

  • USPOULTRY Releases New Video Series Highlighting Poultry and Egg Farm Environmental Stewardship

    U.S. Poultry & Egg Association (USPOULTRY) is releasing a new video series highlighting environmental stewardship on poultry and egg farms. The first video in the series features one of USPOULTRY’s 2014 Family Farm Environmental Excellence Award winners, Bar G Ranch Poultry, in Rogers, Texas. Bar G Ranch Poultry, owned and operated by Darrell and Shannon Glaser, consists of 500 acres in ...

  • Civil enforcement actions taken against beef feedlots in Iowa, Kansas and Nebraska for violations of clean water act (IA, KS, NE)

    EPA Region 7 has taken a series of civil enforcement actions against six beef feedlot operations in Iowa, Kansas and Nebraska for violations of the Clean Water Act, as part of an increased emphasis aimed at ending harmful discharges of pollutants from concentrated animal feeding operations (CAFOs) into the region’s rivers and streams. “EPA Administrator Lisa P. Jackson has made it ...

  • EPA issues compliance orders to seven concentrated animal feeding operations in Iowa, Kansas and Nebraska

  • Workshop Discusses Whether Agriculture Can Significantly Reduce Off-Site Movement of Soluble Nutrients

    Growers who plant cover crops and vegetative systems in agriculture will find that it can tie up phosphorus in a stable phosphorus form that remains in the soil which can increase phosphorus use efficiency, according to a soil researcher from Ohio State’s College of Food, Agricultural, and Environmental Sciences.  The question of whether agriculture can significantly reduce off-site ...

  • Using organic fertilizers could protect against climate change

    Studies show that soil fertilized with organic materials, such as compost, could increase the amount of stored carbon and potentially help slow down greenhouse emissions. Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, ...
