hazd, friable; strongly cacazeous; moderately alkaline; gradual, <br />smooth boundary. <br />C2-20 to 70 inches, yellowish-brown (lOYR 5/4) loam, dark yellowish <br />brown (1 OYR 4/4) when moist; massive; slightly hard, friable: <br />strongly calcareous; moderately alkaline. <br />The A horizon ranges from 6 to 12 inches in thickness and from <br />loam to very fine sand loam in texture. The C horizon is loam or <br />silt loam in texture. Depth to bedrock is typically more than 60 <br />inches, but in some places it is between depths of 40 and 60 inches. <br />Manvel loam (1 to 3 percent slopes) (Me).-This soil is in the north-central part <br />of the Area. Inmost places it occurs as areas more than 30 acres in size. <br />Included with this soil in mapping is a Manvel-like soil that has limestone at a <br />depth of less than 40 inches. Also included are a few small areas of Laporte very fine <br />sandy loam, 5 to 20 percent slopes. These included soils make up about 15 percent <br />of each mapped area. <br />Runoff if medium on this soil. The erosion hazard is moderate. <br />All of the acreage of this soil is used for irrigated and dryland crops and for <br />pasture. (Capability units Ile-1, irrigated, and IVe-4, nonirrigated; tree suitability <br />group 3). <br />McClave Series <br />The McClave series is made up of deep, somewhat poorly drained soils. These <br />soils formed on low terraces and bottom lands in loamy alluvium. Slopes aze 0 to 1 <br />percent. Elevations aze 4,900 to 5,500 feet. The native vegetation is mainly short <br />grasses. Annual precipitation is 12 to 18 inches. Mean annual air temperature is 48° <br />to 52°F., and the frost -free season is about 140 to 155 days. <br />In a representative profile the surface layer, about 40 inches thick, is dark grayish- <br />brown and grayish-brown light clay loam that is mottled in the lower part. The <br />underlying material is mottled, brown light clay loam that extends to a depth of 60 <br />inches or more. Soil reaction is neutral. <br />McClave soils have moderate permeability. Available water capacity for the <br />entire profile is high. Roots can penetrate to a depth of 60 inches or more, and the <br />seasonal high water table is at a depth between 2 and 4 feet. <br />These soils are used for irrigated crops and pasture. <br />Western Mobile Lyons - Rockin' WP [-5 <br />
