In addition, residue removal lowered N fertilizer requirements
across tillage systems in these productive environments, probably due
to a decline in N immobilization . Building
on this previous research, we proposed here to explore the effects of
residue removal rates, tillage, and N fertilization on total carbon (TC)
and nutrient pools within two depths at four experimental sites around
Illinois, after five years since the initiation of the experiments. Results
from this research can assist Illinois farmers interested in harvesting
corn stover for biofuel production to make better decisions to ensure
maintenance of soil productivity in their operations.
