The book addresses the technological developments of erosion processes, methods for their control, policy and social forces shaping the research agenda, and future directions. Conservation techniques conserve water within the biomass and the soil by reducing run-off and keeping the water where it falls, as much as possible. • Conservation measures improve the supply of fuel and forest products. Soil and water conservation structures include all mechanical or structural measures that control the velocity of surface runoff and thus minimize soil erosion and retain water where it is needed. This book offers four specific strategies that can serve as the basis for a national policy to protect soil and water quality while maintaining U.S. agricultural productivity and competitiveness. 3.
