Corn Stover Harvest, Tillage, and Cover Crop Effects on Soil Health Indicators

Corn stover, when removed in excessive amounts, can lead to soil degradation. Though, without stover harvest, producers can face residue management problems with subsequent crops which most often results in an increase in tillage intensity. Cover crops may help offset soil risks posed by removing high quantities of stover. This is dependent of certain condition such as sufficient germination, growth, and termination dates. The objective was to quantify stover harvest rate, tillage practice and cover crops effects on soil properties after five years of continuous corn production in Iowa.
