    Description

    Field guides are presented for estimating site index on each of the three major soil groups in the Ozark Highland Province: limestone-dolomite, sandstone, and fragipan soils. Factors utilized vary by soil groups but include aspect, township, slope shape and depth to pan, with adjustments for hardwood competition. Tabular predictions were within ± 3 feet of measured site values on 83 percent of 41 limestone-dolomite sites, 81 percent of 37 sandstone sites, and 91 percent of 42 fragipan soils.
