The Madison series consists of well drained, moderately permeable soils that formed in residuum weathered from felsic or intermediate, high-grade metamorphic or igneous rocks high in mica content. These soils are very deep to bedrock and moderately deep to saprolite. They are on gently sloping to steep uplands in the Piedmont. Slopes are mostly between 4 and 15 percent, but they range from 2 to 60 percent. Near the type location, mean annual temperature is 59 degrees F and mean annual precipitation is 60 inches.
