Yield values obtained were related through linear regression analysis to those estimated in Soil Survey Reports by the U.S. Department of Agriculture. Highly significant correlations were obtained between predicted yield values and the reference data, although the coefficients of variations were relatively large in some cases. Considerable differences were found in regression coefficients: however, in hyperthermic soils, theses coefficients were close to 1.00. Based on the regression and correlation coefficients, the coefficient of variation, and the number of soils considered, it was concluded that this soil evaluation system or similar systems may be used to evaluate relative soil suitability for specific crop production.
