Increasing demand to use corn plant biomass for producing energy and other products has spurred interest in harvesting corn stover. What is the effect on soil carbon (C) and nitrogen (N) with stover removal? While C is an essential plant nutrient, C fertilization is not practiced as C is supplied to crops via photosynthesis from carbon dioxide (CO2) in air. However, with current issues about greenhouse gases, increased awareness of the importance of soil C sequestration, and efforts to reduce soil erosion, concerns have focused on the impact of corn stover removal.
