Selecting the right amount of tillage is a critical decision for farm energy use and profitability. Similar to other farm management decisions such as nitrogen fertilizer use for corn, or ventilation rate in a livestock confinement, overuse wastes energy but underuse can lower profitability.

A key is to carefully consider potential for gross revenue returns to tillage operations, (i.e., crop yield), in comparison to fuel, labor, and machinery costs for doing tillage. Put another way, are tillage passes beyond a no-till management scheme returning costs of fuel, labor, and machinery that are required of the tillage?

Energy efficiency improvements and on-site solar are viable options for most farmers. More efficient lighting, pumps, and motors can lead to a 20% reduction in electricity use, and solar panels installed on-farm can generate 30-50% of the electricity used in livestock production and/or grain drying.
