It formed in calcareous eolian deposits. Typically the surface layer is pale brown loam about 12 inches thick. The underlying material to a depth of 60 inches is very pale brown silt loam. Permeability is moderate. Available water capacity is 1 high. The effective rooting depth is 60 inches or more. - Surface runoff is slow, and the erosion hazard is low. - This soil is used almost entirely for irrigated crops. It is suited to all crops commonly grown in the area includ- Sog IS ing corn, sugar beets, beans, alfalfa, small grain, It t p o r potatotes, and onions. An example of a suitable cropping D^ system is 3 to 4 years of alfalfa followed by corn, corn for /i C S silage, sugar beets, small grain, or beans. Few conserva- k tion practices are needed to maintain top yields. pen IAAll methods of irrigation are suitable, but furrow ir- 7 7� t= I rigation is the most common. Barnyard manure and com- 76 mercial fertilizer are needed for top yields. 1 ;a Windbreaks and environmental plantings of trees and shrubs commonly grown in they area are generally well ' „76 suited to this soil.
