Liming and Nitrogen Management in Corn



In 1995, a liming study was initiated at the Armstrong Farm where acid soil had developed from extensive nitrogen (N) fertilizer use in continuous corn (CC) production without liming. In 2003, the experimental area was divided into thirds. A corn-soybean (CSb) rotation occupied two-thirds of the area and CC occupied the remaining third. The goals of this experiment were to determine corn crop and soil responses to liming and crop rotation effects on N management.
