Depth to bedrock: 10 to 20 inches <br />Rock fragments: 5 to 35 percent <br />Soil temperature: 52 to 57 degrees F. <br />Reaction: mildly to moderately alkaline <br />A horizon: Hue - 7.5YR or 10YR <br />Value: 4 through 6 dry, 2 through 5 moist <br />Chroma: 2 through 4 <br />Bk horizon: Hue - 5YR through 10YR <br />Value: 5 through 8 dry, 4 through 7 moist <br />Chroma: 2 through 4 <br />Texture: loam, sandy clay loam, or clay loam (averages 18 to 30 percent clay). <br />Calcium carbonate equivalent: 15 to 40 percent <br />COMPETING SERIES: These are the Bisodi (T), Shalaco (T), and Wayneco (T) series. Bisodi, Shalaco <br />and Wayneco soils have less than 18 percent clay. <br />GEOGRAPHIC SETTING: Pinon soils are on knolls, ridges, mesas and hillslopes at elevations of 5,500 <br />to 6,700 feet. Slope gradients range from 1 to 30 percent. These soils formed in alluvium and residuum <br />derived from limestone. Pinon soils are in a warm climate having mean annual temperature ranging <br />from 49 to 56 degrees F., and a mean summer temperature of 64 degrees F. Mean annual <br />precipitation ranges from 10 to 15 inches. The frost-free period is 130 to 170 days. In Colorado these <br />soils have air temperatures ranging from 45 to 48 degrees F. and have a frost-free period of 90 to 130 <br />days with elevations up to 7,400 feet. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Dean and Deama soils and the competing <br />Harvey soils. Dean soils have 40 percent or more carbonate in the control section and they lack a lithic <br />contact within a depth of 20 inches. Deama soils have more than 35 percent rock fragments in the <br />particle-size control section. <br />DRAINAGE AND PERMEABILITY: Well drained; slow surface runoff; moderately slow permeability. <br />USE AND VEGETATION: These soils are used primarily for livestock grazing. Native vegetation is <br />pinyon, juniper, grama grass and shrubs. <br />(Revised June 2008) Attachment 2.04.9-3-32
