Permeability is moderate in the loess and in the residuum and ranges from slow to moderate in the sandstone. Slopes range from 2 to 35 percent. Mean annual precipitation is about 30 inches. La Farge silt loam - on a convex 12 percent slope in a hay field at an elevation of about 1,105 feet. Depth to the base of the argillic horizon, depth to the paralithic contact with sandstone, and thickness of the loess mantle all range from 20 to 40 inches.
Coarse fragments are absent in the loess mantle.
Volume of sandstone channers ranges from 0 to 15 percent in the residuum. Reaction typically ranges from very strongly acid to moderately acid in the solum but ranges to neutral in the upper part, where the soil is limed. The Ap horizon has value of 3 or 4 and chroma of 2 or 3. Colors with moist value of 3 have dry value of 6 or more. Uncultivated pedons have an A horizon with hue of 10YR, value of 2 or 3 and chroma of 1 or 2.
