      Questioning Lagoon Greenhouse Gas Estimates
    The American Society of Agronomy reports that University of Missouri (UM) scientists are questioning the approach the U.S. Environmental Protection Agency (EPA) uses to estimate greenhouse gas emissions from agricultural anaerobic lagoons that treat manure. According to the scientists, the EPA methodology contains errors and may underestimate methane emissions by up to 65%.

    Now’s the Time to incorporate a Slurrystore System into your nutrient management program. Slurrystore is compatible for any system whether your goal is long term storage, nutrient retention, green containment, digesters or manure processing. Plus Slurrystore Systems include the added feature of agitation to help ensure nutrient consistency. Click here or contact your local Authorized Slurrystore Dealer for more information.

      Multi-State Team Researches Beef Barn Emissions
    A tri-state team of researchers and university specialists will soon engage in a three-year study looking at gases emitted from mono-slope beef barns, looking at how building management impacts the emissions. The team is composed of researchers from the USDA’s Meat Animal Research Center (USMARC), Clay Center, NE; agricultural engineering specialists from South Dakota State University (SDSU), Brookings, SD; and extension program specialists from Iowa State University (ISU), Ames, IA.

      Manure Shows Higher Returns than Chemical Fertilizer
    The Texas AgriLife Extension Service of Texas A&M University reports that although no significant differences in corn yield were found between organic and chemical sources of nutrients, a Texas AgriLife Research economist found manure generates higher economic returns than anhydrous ammonia.

      Wisconsin Phosphorus Rules Approved
    The Wisconsin Natural Resources Board recently approved a set of rules designed to address phosphorous and other nutrient pollution, as well as help control erosion and sedimentation in the state. Wisconsin farmers will be able to obtain up to 70% of the costs of implementing non-point pollution controls to meet the standards set by the new rules, according to the Wisconsin Department of Natural Resources (DNR)

      Manitoba Projects Zero in on Manure Issues
    The Manitoba Livestock Manure Management Initiative’s board of directors recently approved two new research projects designed to help livestock producers in the province.

    A University o f Manitoba project, overseen by Jan Plaizier, Department of animal Science, will develop management practices to help reduce on-farm accumulation of phosphorus and potassium. The research is expected to help farmers overcome challenges associated with shifting from nitrogen-based to phosphorus-based manure management regulations. The research will also look at opportunities for using swine manure on dairy farms. Manure-sharing partnerships between swine and dairy producers could help reduce the need for dairy farmers to purchase synthetic fertilizer while providing swine producers with more land for manure spreading. More information about this project is available online at www.manure.mb.ca/81.

    The second project will seek to develop an economical means of separating phosphorus from swine manure in order to help producers meet regulatory soil test limits. Developing an improved, gravity-based technology for separating solids and liquids from swine manure will be a step toward creating value-added products for producers. The project is being overseen by Francis Zvomuya, University of Manitoba Department of Soil Science. Learn more about this project at www.manure.mb.ca/82.

      Publication Looks at Manure-Based Fuel
    The Texas AgriLife Extension Service online bookstore offers a publication that explains the properties of dairy manure that could make it an excellent source of fuel. The six-page publication entitled, “Dairy Biomass as a Renewable Fuel Source,” is listed as publication number L-5494 on the site. Researchers are investigating new sources of cleaner, cheaper and more environmentally friendly fuel from dairy biomass. The publication features three tables and four photos and costs for $3.00.

      Develop a Manure Spill Action Plan
    The eXtension Livestock and Poultry Environmental Learning Center will host a webcast on July 9 entitled, "Planning for Manure Spills." The session will cover practical and legal issues related to emergency action plans for animal feeding operations and confined animal feeding operations (CAFOs). Two case studies will profile liquid manure accident recovery. The webcast will touch on the basics of formulating an emergency action plan, identifying resources, reporting, manure transportation accidents, over-application, considerations for dry manure and litter, and preventive maintenance of manure handling structures.

    The webcast starts at 1:30 p.m. (Central Standard Time). Additional information can be found at: www.extension.org/.

      Manure Expo Offers Demos, Speakers
    Nutrient management experts from eight states will be speaking as part of the upcoming 2010 Manure Expo, to be held July 15 at the Russell E. Larson Agricultural Research Center at Rock Springs, nine miles southwest of State College, PA.

    A variety of manure technology demonstrations will be taking place on the 55-acre site. A manure industry trade show will feature approximately 50 exhibits, according to event organizers. The expo's theme is, "Balancing Production and Conservation.” Attendees will have opportunities to learn about adding value to manure. Speakers, displays and demonstrations will highlight the most recent and complete information available, covering everything from composting to solid/liquid separation to digesters and other storage and handling technologies. The Manure Expo offers free parking and admission and will take place from 8:30 a.m. to 4:00 p.m.

    For more information, call (814) 863-2873, e-mail: ManureExpo@psu.edu, or visit www.das.psu.edu/.


      Manure Application Demos at Farm Technology Days
    Manure application demonstrations will be part of the upcoming Wisconsin Farm Technology Days, July 20-22, River Falls, WI. A demonstration plot just outside of the Applied Technology Center at the event will showcase the differences in spreading rates and application timing of manure on established alfalfa fields. Two manure application rates of 3000 gallons and 10,000 gallons applied immediately after harvest of the small plot. An additional late application will be made to demonstrate its impact on alfalfa regrowth. University of Wisconsin (UW) Extension staff will be available to answer questions and share the latest research regarding rates and timing of manure applications to alfalfa.

    Visitors to the Applied Technology Center tent will have an opportunity to learn more about the technology behind Precision Manure Placement and view the manure application maps generated during the manure demonstrations which occurred the day prior. The maps will detail the rates and paths of application and can be compared against the nutrient management plan recommendations for the field.

    The Professional Nutrient Applicators Association of Wisconsin (PNAAW) will also be available to share information about their association.

      Dairy & Feedlot Field Day Plans Set
    A Small Dairy and Open Feedlot Manure Management Field Day will be hosted by Fick’s Swiss Farm, owned by Galen and Sandy Fick, Boyden, IA, from 1:00 to 3:00 p.m. on July 23. The field day will provide manure management information and technical assistance geared specifically for small and medium-sized dairies and open feedlots. Recent state and federal inspections in Iowa have increased the awareness of manure runoff issues and have put pressure on producers to better manage manure. The learning opportunities available during the field day will come from sessions covering Environmental Protection Agency (EPA) and Iowa Department of Natural Resources (DNR) regulatory issues, National Resources Conservation Service (NRCS) technical assistance and cost-share opportunities, manure sample analysis and what it means for a cropping system, and manure spreader calibration. Local implement dealers will be contributing to a manure application equipment showcase. Contact Chris Mondak or Beth Doran at the Sioux County Extension Office for more details at (712) 737-4230, or visit www.agronext.iastate.edu/ for more information.


      Waste Management Symposium Scheduled
    The 2010 Poultry and Animal Waste Management Symposium will be held Oct. 26-28 at the Sheraton Greensboro at Four Seasons, Greensboro, NC. The program includes environmental facilities tours, a trade show, and educational sessions covering topics ranging from Environmental Protection Agency and state regulations, to carbon markets and waste treatment technologies.
