Former competitors <br />in the previous classification (Lithic Ustollic) are the Berto, Bondman, Frontier, and Kech series. <br />Berto soils have calcic horizons. Bondman soils have soil temperatures ranging from 47 to 50 <br />degrees F, and receive more winter moisture. Frontier and Kech soils have horizons with <br />segregated secondary carbonates. In addition, Frontier soils have hue yellower than 7.5YR in the <br />argillic horizon. <br />GEOGRAPHIC SETTING: Bond soils are on cuestas, mesas, hills, and ridges with slopes ranging <br />from 0 to 50 percent. They formed in alluvial and eolian deposits from sandstone. Elevations are <br />5,600 to 7,000 feet. Typically, the average annual precipitation is 10 to 13 inches, but ranges to 15 <br />inches in some areas; mean annual temperature is 49 to 54 degrees F. The frost -free period is 110 <br />to 160 days. In Colorado, the temperature ranges as low as 43 degrees F. In Arizona elevations are <br />as low as 4500 feet, temperatures as high 55 degrees and frost free as long as 165 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Aparejo, Hagerman, Penistaja and <br />Skyvillage soils. Aparejo and Penistaja soils are deep. Hagerman soils have lithic contact between <br />20 and 40 inches. Skyvillage soils do not have argillic horizons. <br />DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately permeable. <br />USE AND VEGETATION: The major use of this soil is for livestock grazing. The present vegetation <br />is blue grama, sideoats grama, New Mexico feathergrass, Indian ricegrass, scattered oneseed <br />juniper, and winterfat. <br />DISTRIBUTION AND EXTENT: West - central New Mexico, Northern Arizona, southwestern <br />Revised September 2010 (PRO6) Attachment 2.04.9 -3 -8 <br />
