Title: Nitrogen Fixation and Rotational Benefits of Soybean Grown in Rotation with Corn
Principle Investigator: E.S. Oplinger / UW–Madison, Agronomy
Objective: To determine if the primary beneficial effect of growing soybean in rotation with corn is due to nitrogen-fixation or to some other unknown growth promoting factors.
