Tillage selection is just one of the issues that farmers must address when making crop production decisions. Among the factors that will influence the choice of tillage for a given field is the condition of the residue and soil in the field; the residue management practices needed to meet conservation plan specifications; the tools, time, and money that are available; the need to incorporate amendments such as lime, fertilizer, and manure; and personal experience as to what works for their rotation, soil type, and production system. The soil will have a varied condition depending on the tillage management and this may influence the response of the crop to applied nutrients.
