Popis:	Three tillage systems for soybeans in the Western Corn Belt were compared: conventional, reduced-till, and no-till. Production budgets are presented for various assumptions on the relative yields under these three systems. Energy output-input ratios were favorable for the reduced-till and no-till systems. For a model corn-soybeans-hog farm, these two systems were also more profitable than conventional tillage at 1976 crop and input prices.
