The interrelations of littleleaf, site index, soil, and ground cover in Piedmont shortleaf pine stands (1955)Copeland, O. L., & McAlpine, R. G. (1955).

Retrieved from http://www.jstor.org/stable/1931301?seq=1#page_scan_tab_contents The shortleaf pine forest type area increased 5.0 per cent, or from 2.0 to 2.1 million acres from 1936 to 1947. This increase was due chiefly to the reversion of a large acreage of agricultural land to forests. Much of this agricultural land was abandoned because it had deteriorated to such an extent that it no longer was profitable for farm- ing. The severity of soil changes induced by culti- vation under poor management practices has been studied by Hoover (1949). He showed that the non-capillary storage capacity of water in the top 2 feet of an uncultivated Vance forest soil was 4.05 inches, while in a similar soil cultivated and then abandoned 35 years ago and now supporting shortleaf pine, the non-capillary storage capacity was only 1.21 inches for the same depth. Similarly, in the surface soil the water percolation rate was twice as great in the uncultivated forest soil as in the abandoned field soil. In the subsoil, the rate was 60 times greater in the forest than in the old-field soil. In 1949-1950. a soils-littleleaf survey was made in certain Piedmont counties of South Carolina and Georgia. This survey had several objectives (1) to determine the relationship between little- leaf and soils on a wide area, (2) to evaluate spe- cific soil factors associated with the incidence of littleleaf, and (3) to ascertain the occurrence of the fungus Phytophlthlora ciuinawuomiii Rands in relation to littleleaf incidence and soil factors. Much of the information pertaining directly to littleleaf has been published by Campbell and Copeland (1954). Therefore, the object of this report is to summarize the soil conditions of South Carolina Piedmont shortleaf pine stands in relation to little- leaf and site index http://www.jstor.org/stable/1931301?seq=1#page_scan_tab_contents
