<br />Km--Kim loam, 1 to 3 pnrennl nlupen. "I'hlrr derryr, wall dtr~lued <br />soil Se on gently sloping uplands. IC formed in mixed material. The <br />native vegetation is mainly grass. The average annual precipitation is 13 <br />to 17 inches. <br />Typically, the surface layer is light brownish gray calcareous loam <br />about 9 inches thick. The upper 21 inches of the substratum is very pale <br />brown calcareous loam. The tower part to a depth of 60 inches 1s light <br />yellowish brown calcareous sandy clay loam. <br />Included in this unit are small areas of Fort Collins and Stoneham <br />soils. Both differ in having a subsoil. <br />Permeability of the Kim soil is moderate. Available water capacity is <br />high. Effective rooting depth is 60 inches or more. Runoff is medium, and <br />the hazard of water erosion is moderate. The hazard of soil blowing is <br />high. <br />This unit is used mainly as rangeland.

Tillage operations should be kept to a minimum to <br />conserve surface residue. Terraces are helpful in reducing runoff. Where <br />flat channel terraces are used, fertilizing the channels with nitrogen and <br />phosphorus is beneficial. <br />
