This report is designed to provide access to, and interpretation of, Missouri soil data generated in a study of 500 farm-field plots in 1978 and 1979. The objective of the study was to quantify the relationships between soil properties and soil productivity. The study procedure was to sample and characterize soils at randomly located plots in fields where com or soybeans were being grown, and from that characterization, to estimate soil productivity. The results of the study were two-fold. First, soils information was generated. Second, a model called a soil productivity index was developed (Neill 1979, Kiniry et al. 1983) that converted soil properties into estimates of soil productivity.
