  1. 100% Agronomy Series #145: Pennsylvania State University Soil Characterization Laboratory Database System Documentation [pdf]Get Acrobat Reader
    Source: Department of Crop and Soil Sciences Publications

    "Soils have been sampled and analyzed in Pennsylvania for characterization since 1954. The initial sampling was done by the USDA Soil Conservation Service (SCS) now known as the USDA Natural Resources Conservation Service (NRCS). Subsequent samplings have been done by the Penn State Soil Characterization Laboratory, US Environmental Protection Agency (EPA), and the NRCS. Presently, 949 pedons (profiles) have been collected and analyzed. An account of the history of the sampling is given in Ciolkosz (1998). Initially the data (site, horizon, and laboratory) was available in hard copy printed form. Since the development of the computer, particularly the PC with large data capacities, the Pennsylvania analysis system and data have been computerized (see Ciolkosz, 2000; Ciolkosz and Thurman, 1992, 1994; Thurman et al., 1994). In order for a computer system to have longevity as it is modified and updated by computer programmers, the data system must be documented. Thus, the objective of this publication is to document the Penn State University Soil Characterization Laboratory Database System."
