Start Date: Jul 01, 2012
End Date: Dec 30, 2014
Identify soil microbiological indicators and quantify benefits of soil microbiological processes associated with agricultural management practices. Specifically, within corn production systems, evaluate cover cropping for reducing P inputs by stimulation of soil microorganisms, particularly arbuscular mycorrhizal fungi.
Establish (or use existing) replicated plots with differing fall cover crop treatments within corn cropping systems at three locations (Brookings, Dakota Lakes, TBD) including a check. Through plant and soil analyses, determine effect of cover crop on biological measures and their link to the seasonal bioavailability of plant nutrients.
