The purpose of this study was to determine if five edaphic factors were correlated with herbage production in a side-oats grama community and if so, to develop linear regression equations to use as predictors of production. The study area was located at Cedar Bluff Reservoir, Trego County, Kansas. Contour lines at one-foot intervals were located on the study area, each being sampled by quadrats for soil depth, clay content, silt content, sand content, and rock content as well as production of forbs and grass species. A correlation matrix was developed for the 12 variables sampled within each quadrat. From the matrix, soil depth and rock content were selected to develop linear regression equations to predict total production, total grass production, and side-oats grama production. The results indicate that as soil depth increased and rock content decreased, production tended to increase. On the study area, soil decreased, production tended to increase. In the study area, soil depth and rock content were found by means of a linear regression equation to have limited use as predictors of total production, total grass production, and side-oats grama production.
