Warsaw soils formed in loamy sediments and in the underlying gravelly outwash over calcareous, stratified gravelly or very gravelly coarse sand and sand. The mean annual temperature ranges from 48 to 53 degrees F, and mean annual precipitation ranges from 30 to 42 inches, and elevation ranges from 580 feet to 1530 feet above sea level. The well drained Elston and Wea soils, the excessively drained Ade and Rodman soils, and the very poorly drained Westland soils are closely associated with the Warsaw soils. Elston soils have less clay in the subsoil and are on adjacent nearly level or gently sloping areas. Rodman soils are on the breaks and steeper ridges and are more sandy.
Westland soils are in the lower flats and depressions, and are gray throughout with brown mottles.
The Ade soils are closely associated with Warsaw in areas where there are small sandy ridges and contain less clay throughout the profile. Warsaw soils grade to Wea soils where the solum is more than 40 inches thick on similar landscape positions. The potential for surface runoff is low or medium. Permeability is moderate in the solum and very rapid in the substratum. Mostly used for growing crops.
