Energy Efficiencies of Farming Wheat, Corn, and Potatoes OrganicallyASA Special Publication, Organic Farming: Current Technology and its Role in a Sustainable Agriculture (1984)
Since the mid-1930's, agricultural productivity measured in crop yield per acre has more than doubled. The USA now dominated the world's grain exports and in fiscal 1981, U.S. agricultural exports are projected to reach a record $45 billion. This high level of productivity has been due largely to the mobilization of energy resources in agricultural production combined with the use of high-yielding crop varieties and in part to timeliness of operations and other cultural practices.
