Development and Testing of Some Average Relations for Predicting Soil Moisture
Abstract
Detailed observations made in previous studies of sites distributed throughout the United States were used to derive average soil-moisture relations for use in applying previously developed soil-moisture content prediction methods to sites for which no specific data on the moisture regime are available. The average relations were tested on 24 sites that had been used in the development of prediction method, on 10 sites for which soil strength and moisture data were available, and on 617 sites located throughout the United States for which detailed data were not available. Predicted and measured values were compared, and the accuracy of predicton of soil moisture was within reasonable limits of error for well-drained soils. Appendices give the prediction method developed and a sample of its application, describe the 617 sites with limited data used in this investigation, and present results of special studies made to improve the accuracy of the prediction method.
