Abstract

By carefully limiting the area of application and the soils included in individual analyses, practical equations were developed for predicting shortleaf pine (Pinus echinata Mill.) growth on major soils in the Ozark Highlands. Large pits were dug to adequately classify the soils, and soil properties were determined by standard techniques. Shortleaf pine site index at age 50 was correlated with aspect, slope shape, loss-on-ignition of the AI and A_pl horizons, depth to fragipan, and latitude. Regression equations developed for limestone and dolomite soils,sandstone soils, and fragipan soils predicted site indexes within an average of 0.6 m (2 feet) on confirmatory plots.
