Abstract

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.Because cattle feeding is a major industry in the area, cattle hoop building manure was incorporated into the experiment in 2006 to evaluate soil acidity effects on its utilization by a corn crop and also on soil test values.
