How is soil map data used?
Lancaster County was soil-typed in the early 1970’s by soil scientist from the U.S. Department of Agriculture Soil Conservation Service. Rough estimate percolation rates were derived for each soil type. When soil type data is superimposed over an aerial photograph, an idea of the suitability of a given parcel of land can be determined. Soil characteristics must be verified in the field by a percolation test.
