The field work for the soil survey of Accomack County was completed in 1988 by the Department of Crop and Soil Environmental Sciences, Virginia Polytechnic Institute and State University, Research Division, in cooperation with the Soil Conservation Service of the United States Department of Agriculture, the Eastern Shore Soil and Water Conservation District, and the Accomack County Board of Supervisors. This survey was made to determine the kinds of soils within Accomack County and how they can be used to their fullest potential. Soil scientists observed the steepness, length, and shape of slopes; the size of streams and general pattern of drainage; and the kinds of native plants or crops. They selected areas of representative soils in which to dig pits to describe and sample the soils. They randomly selected sites to bore auger holes to describe and sample soil profiles in order to evaluate distributions of soil properties within the map units. A profile is the sequence of natural layers, or horizons, in a soil. It extends from the land surface down into the parent material or unconsolidated sediments that have been changed little by climate, relief, and organisms over time. Soil maps were produced by soil scientists who drew boundaries, on aerial photographs, of the kinds of soils observed in the survey area. These photographs show trees, buildings, fields, roads, and other natural and cultural features that were used to locate these soil boundaries. Mapping units are collections of delineated soil bodies identified by a single symbol on soil maps. Most mapping units represent natural soil bodies composed of one kind of soil or of soils with similar properties and responses to use and management. Other mapping units are made up of two or more kinds of soils. Because the Soil Survey of Accomack County, Virginia, does not include the laboratory data used to characterize, classify, and interpret the soils within the mapping units, this report presents those data.
