Texture is variable, ranging from silt loam to clay.
Taft is the only series in this family. Soils in similar families are the Dickson , Guthrie , Leadvale , and Sango series. Dickson soils lack gray mottles in the upper 10 inches of the B horizon, and are better drained than Taft soils. Guthrie soils have dominant chroma of 2 or less between the base of the Ap horizons and the fragipans. Leadvale soils lack gray mottles in the upper 10 inches of the B horizons and have argillic horizons above the fragipan.
