Swine Manure Nitrogen Availability and Carryover

Authors: Greg Brenneman (Iowa State University) , Kevin Van Dee (Iowa State University)

Abstract

Swine manure is readily available in Iowa and is an excellent source of fertilizer for crops. Application rates are often based on the nitrogen (N) needs of the coming year’s crop. Producers often ask how much N is available the first year, and if any N carries over to subsequent years.
