Combining cover crops and manure becomes a winning combination to capture and recycle nutrients, protect the soil from erosion and add organic matter while decreasing the environmental risks with liquid manure applications. Slurry seeding is an integrated process that incorporates low-disturbance tillage, manure application and seeding of forages and cover crops in one efficient trip over the field.
Two Webcast presenters will provide research results and answer questions. The free educational webcast is from the Livestock and Poultry Environmental Learning Center of eXtension.
Speakers
Jeremy Singer is a research agronomist with the USDA Agricultural Research Service located in Ames, Iowa at the National Laboratory for Agriculture and the Environment. He earned his Ph.D. at Cornell University. Singer’s research quantifies water and radiation interactions on plant ecology in systems with varying tillage intensity, organic amendments and cover crops.
Tim Harrigan is an associate professor of Bio Systems and Agricultural Engineering at Michigan State University. His research and Extension programs focus on mitigating adverse farming systems impacts on the environment and creating sustainable agroecosystems. His research includes the development of an innovative process that combines low-disturbance tillage, the seeding of forage and cover crops and manure land application in one sustainable operation. Currently, he is evaluating effects of the die-off and regrowth of root systems on the fate and transport of manure contaminants in the soil. Harrigan received his B.S. in dairy science and Ph.D. in bio systems and agricultural engineering from Michigan State.
The Friday, Jan. 15 session begins at 2:30 p.m. Eastern Standard Time. The webcast meeting room opens 15 minutes before the start time. Go to http://www.extension.org/wiki/Live_Webcast_Information to view.
Monthly webcasts are hosted by the Livestock and Poultry Environmental (LPE) Learning Center, an information resource developed by more than 150 experts from land-grant universities, agencies and other organizations. The center is part of the national eXtension interactive Web resource. Webcasts are archived at http://www.extension.org/wiki/Archived_Webcasts%2C_Livestock_and_Poultry_Environmental_Learning_Center.
LPE Learning Center
The center advocates that individuals involved in public policy issues, animal production and delivery of technical services for animal producers should have on-demand access to the nation's best science-based resources. Articles about animal manure management are at http://www.extension.org/animal+manure+management.
eXtension is an educational partnership helping Americans improve their lives with access to timely, objective, research-based information and educational opportunities. Land-grant universities were founded on the ideals that higher education should be accessible to all, that colleges should teach liberal and practical subjects and share knowledge with people throughout their states.
