The plowshare may well have destroyed more options for future generations than the sword, writes Wes Jackson in a review of practices that have brought U.S. agriculture to the edge of disaster. Tillage has hastened the erosion of irreplaceable topsoil everywhere and a technology based on fossil fuels has increased yields for short-term profits, leaving crops ever more vulnerable to diseases, pests, and droughts. Such, says Jackson, is the failure of success. As high-technology agriculture becomes more wasteful and expensive, more farmers are being forced off the land or into bankruptcy. Jacksons major solution calls for the development of plant combinations that yield food while holding the soil and re-newing its nutrients without plowing or applying fossil-fuel-based fertilizers or pesticides. His new way of raising crops, by working with the soils natural systems, would keep the worlds bread-basket producing perpetually.About author(s):Wes Jackson and his wife, Dana, are directors of the Land Institute, a research and educational organization near Salina, Kansas, where they are currently breeding seed-producing perennials that could revolutionize world and American agriculture within fifty years.
