Utilizing Liquid Livestock Manure as a Top-dress to Wheat and Side-dress to Corn

This webcast discusses five years of on-farm research plots where liquid swine and dairy manure has been applied to soft red winter wheat fields and compared to urea as a spring top-dress nitrogen source. Research plots have utilized a Veenhuizen toolbar and a Peecon toolbar to incorporate liquid manure into standing wheat and more recently a dragline has been utilized to make manure application more efficient and reduce soil compaction.

Air Emissions After Manure Land Application Including Subsurface Application of Poultry Litter and Solid Manure

When manure is land applied there are many different gases emitted, including greenhouse gases and those that contribute to odors. How much is emitted and how does that change with different application methods? This presentation was originally broadcast on September 18, 2009.
