The Doylestown series consists of deep, poorly drained soils. These soils formed in silty materials, presumably eolian deposits, over soil materials weathered from a variety of parent materials, but principally red shale. They are on concave upland slopes of 0 to 5 percent.
Permeability is slow.
Doylestown silt loam, on 3 to 8 percent southeast facing slopes in a cultivated field. Solum thickness and thickness of the silt mantle ranges from 40 to 60 inches. Depth to the fragipan ranges from 15 to 25 inches. Rock fragments of shale are less than 5 percent in the upper part of the solum and range from 5 to 20 percent in the lower part. Reaction is very strongly acid and strongly acid in the upper part of the solum and ranges from strongly acid to neutral in the lower part of the solum in unlimed soils.
