Abstract

The purpose of this study was to find if any correlations exist between soil depth, basal cover, and production of Mixed Prairie vegetation. An effort was made to eliminate the influence of all soil factors other than soil depth. Samples were taken at regular intervals from the same contour position on the slope and from similar slope exposures. Each sample consisted of measurement of basal cover, composition, production of vegetation, and determination of soil depth. In an attempt to correlate soil depth to various factors of native vegetation, 14 variables were chosen and correlated with each other. The soil depths recorded were categorized into four groups; 1) 0"-4", (2) 4"-12", (3) 12"-20 ", (4) 20 +". An analysis of variance and Duncan’s multiple range tests was applied to the variables displaying a significant F-value. The results indicated that soil depth has a definite effect on basal cover and production of vegetation located on break sites in the Mixed Prairie.
