    Tillage is a tool for managing many things that can go wrong on a given field. It breaks compaction (if done at the right soil moisture), improves drainage (again if done at the right soil moisture), and manages inoculum loads from residue borne insects and pathogens that impact corn, soybean, and wheat. Just like pesticides and fertilizers – too much tillage also can bring another set of problems, a compacted plow layer, but more importantly, soil erosion. With any agronomic practice, including tillage, there are benefits and drawbacks.

A much greater level of management is needed for crop production benefits than for environmental benefits. Our suggested maximum target outlet water levels settings are illustrated in Figure 1.
