Scullin soils have a lithic contact and contain 5 to 50 percent by volume of cherty or dolomitic limestone in the Bt horizon. Ren soils are on nearly level to gently sloping broad, smooth convex ridges and side slopes of uplands in the Central Rolling Red Prairies. Slopes are 0 to 3 percent. Masham soils are shallow, and are on lower side slopes or convex knolls and ridges. Runoff is slow or medium.
Permeability is very slow.
Nearly all areas are cultivated. Principal crops are wheat and grain sorghum. Native vegetation was tall and mid grasses. The series is of moderate extent. Reno County, Kansas, 1989.
