Strip-Tillage Effects on Corn Performance and Soil Properties
The perceived effect of no-tillage on soil temperature, soil moisture conditions, soil compaction, soil productivity, and nitrogen movement and availability has become a major concern among producers considering adopting this tillage system. No-tillage presents a unique challenge in poorly drained soils, in which certain surface soil properties are affected due to the absence of tillage as a corrective measure. Effective tillage systems create an ideal seedbed condition (i.e., soil moisture, temperature, and penetration resistance) for plant emergence, plant development, and unimpeded root growth. However, the integration of tillage and nitrogen (N) management (i.e., type of tillage system, timing of tillage system, timing of N application, and N rate) also presents significant challenges for producing corn, sustaining soil productivity, and improving water quality.
