Crop residue cover and tillage practices play important roles in the way that crops use water, and also affect the ability of irrigation systems to replace that water. The effects of these practices and other influencing factors are discussed in this NebGuide. Tillage practices and crop residue management play an important role in the way that irrigation systems perform and are managed. Tillage practices affect the way that water moves into and off of the soil (infiltration and runoff). Tillage practices also affect the way that water moves from the soil into the atmosphere (evapotranspiration).
