This year, as producers decide whether to till or not, special consideration should be given to high fuel prices. Generally, producers know what it takes to operate tillage implements and how much fuel it would take to finish the work. Conventional tillage plus planting and spraying in general would require approximately three to four gallons of fuel per acre compared to one gallon per acre for no-tillage. Field operations in general, including tillage and harvesting, along with nitrogen fertilizer use and crop drying consume most of the crop production energy.
