This document presents objectives and results of the Field Appraisal of Resource Management Systems (FARMS) study'S second year. The principal objectives of FARMS were to study the relationship of crop yields to soil erosion and to simulate the economic nature of this relationship. Crop management, soils, conservation practices and management, crop yields, soil chemistry, and sociological data were collected from 800 plots in 1981. This report presents statistics for rill and sheet soil erosion, which are estimated by the Universal Soil Loss Equation (USLE) and assumed to represent a long-term rather than short-term effect. The report also presents summary statistics …
