Determine the amount of corn stover residue needed to maintain soil C content (soil quality) and crop productivity.
The core, multi-location field experiment will include replicated plots established on a highly productive soil series using no tillage continuous corn and no tillage corn/soybean with rye cover crop rotation following standard agronomic management practices. The corn stover harvest treatments will consist of 0, ~50, and maximum possible residue removal. Corn will be grown using standard commercial practices including pre-emergence herbicides, NPK fertilization and insecticides as necessary. Soybeans will be grown using standard no-till commercial practices with post-emergent herbicides and insecticides as necessary.
