    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.

    Setting Outlet Water Level in Drainage Water Management Structures

    Author(s): Larry Brown , Author(s): Norman Fausey

    Drainage Water Management (DWMgt) is first and foremost an environmental protection practice intended to reduce nutrient delivery to streams, ditches, streams and lakes. However, DWMgt may have some production benefits, but it is not primarily a production practice. Non-growing season (winter) management is essential to realize the environmental benefits. 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.
