The Dickson series consists of very deep, moderately well drained soils that formed in a silty mantle 2 to 4 feet thick and in the underlying limestone residuum. The Dickson series is characterized by a firm and brittle fragipan that is 18 to 36 inches below the soil surface. Most areas of these soils are on nearly level to gently sloping uplands, with slopes ranging from 0 to 12 percent. The average annual temperature is about 60 degrees F., and average annual precipitation is about 50 inches. Fine-silty, siliceous, semiactive, thermic Glossic Fragiudults Uses Corn and soybeans are the principal row crops.
Most pastures support tall fescue and white clover.
Most areas are cleared and used for growing hay, pasture, small grains, corn, soybeans, and tobacco. Some areas are in forest chiefly of oaks, yellow-poplar, hickories, gums, and maples. Links Learn more about Dickson soils from the National Cooperative Soil Survey .
