Soil Depletion Estimates: Version 2. A User's Guide to a Personal Computer Modelfor Estimating Long-Term Onsite Physical and Economic Impacts of Soil Depletion

摘要

The Soil Depletion Estimates model produces results that allow comparison ofshortrun and longrun impacts on erosion and economic returns from alternative resource management systems. For each specified soil and resource management system, the model generates long-term onsite soil depletion effects and estimates the economic impacts over incremental time periods. The method allows the selection of resource management systems based on economic profitability under alternative erosion control objectives. Prioritizing soil-resource management system combinations for targeting the application of soil erosion control measures is also possible by ranking one of the model output coefficients.
