The objective of this study is to reach a judgment of the amount of U.S. cropland likely to be in some form of conservation tillage in 2010. The future spread of conservation tillage will be conditioned primarily by farmers' perceptions of its economic advantages relative to conventional tillage and by the society's perceptions of its advantages and disadvantages with respect to the environment. Accordingly, the study first considers the economics of conservation tillage relative to conventional tillage, examining differences between the two technologies in the quantities of resources used and in yields. The conclusion is that conservation tillage typically uses less of certain resources and more of others, but that on balance it requires 5 to 10 percent less expenditure per acre than conventional tillage.
