The McAfee series consists of moderately deep, well drained soils formed in residuum of limestone on upland ridgetops and sideslopes.
Permeability is moderately slow.
The average annual precipitation is about 45 inches, and the average annual temperature is about 54 degrees F. Slopes range from 2 to 50 percent. Solum thickness and depth to limestone bedrock ranges from 20 to 40 inches. The soil ranges from medium acid to neutral in the solum, and from slightly acid or mildly alkaline in the C horizon. Fragments of chert from 2 mm to 3 inches across, or fragments of limestone, from 1 to 6 inches across, range from 0 to 15 percent in the solum, and from 0 to 25 percent in the C horizon. The Ap horizon has hue of 10YR to 5YR, value less than 4, and chroma 2 to 4.
