    Corn Harvest and Nutrient Management Systems Impacts on Phosphorus Loss with Surface Runoff

Abstract

Cellulosic biomass is being promoted for use in future bioenergy production systems as a better alternative to current grain-based systems. Cropping systems and partial or total corn biomass removal in addition to grain harvest changes crop P needs, crop residue, and P recycling.Both sediment and water losses may also be altered and these changes could result in increased P loss from fields. Livestock production results in the generation of large quantities of manure that is a valuable nutrient source for producing high biomass yield. Manure can be used to minimize use of inorganic fertilizers and enhance production efficiency. Therefore, this study evaluated the impacts of several crop and corn biomass harvest systems on P loss with surface runoff as affected by management based on fertilizers or liquid swine manure.
