Tillage operations are generally conducted to prepare a seedbed, incorporate fertilizers, and cultivate for weed control. The number of trips required to perform these operations depends on soil type and condition, the crop, weather conditions, and the type of tillage system utilized. Excessive tillage operations increase fuel consumption, operating costs, machinery wear, and time and labor requirements. Too much tillage also increases soil compaction and releases carbon into the atmosphere.

Field efficiency means completing a particular field operation while wasting the least amount of time, fuel, and farm resources. The term refers to the time the operation should take vs. turning and other nonproductive time. For example, spending an inordinate amount of time turning around at the ends of short, wide fields or overlapping tillage operations within a field can result in higher fuel consumption per acre.
Machine maintenance and repair also affect field efficiency – equipment that is …
