Research suggests that an additional period of cover crop growth prior to soybeans results in high cover crop biomass production, nitrogen retention and has no negative effect on yield.

Michael Castellano, assistant agronomy professor at Iowa State University, will share his research on nitrogen and soil organic matter during the Iowa Learning Farms’ monthly webinar Wednesday, July 17. The at 11:30 a.m. webinar is part of a free series, hosted by ILF, through Adobe Connect.
