Former <br />competitors in the previous classification (Lithic Ustollic) are the Berto, Bondman, <br />Frontier, and Kech series. Berto soils have calcic horizons. Bondman soils have soil <br />temperatures ranging from 47 to 50 degrees F, and receive more winter moisture. <br />Frontier and Kech soils have horizons with segregated secondary carbonates. In <br />addition, Frontier soils have hue yellower than 7.5YR in the argillic horizon. <br />GEOGRAPHIC SETTING: Bond soils are on cuestas, mesas, hills, and ridges with <br />slopes ranging from 0 to 50 percent. They formed in alluvial and eolian deposits from <br />sandstone. Elevations are 5,600 to 7,000 feet. Typically, the average annual <br />precipitation is 10 to 13 inches, but ranges to 15 inches in some areas; mean annual <br />temperature is 49 to 54 degrees F. The frost-free period is 110 to 160 days. In Colorado, <br />the temperature ranges as low as 43 degrees F. In Arizona elevations are as low as <br />4500 feet, temperatures as high 55 degrees and frost free as long as 165 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the A are'o, Hagerman, <br />Penistaia and S~illaae soils. Aparejo and Penistaja soils are deep. Hagerman soils <br />have lithic contact between 20 and 40 inches. Skyvillage soils do not have argillic <br />horizons. <br />DRAINAGE AND PERMEABILITY: Well drained; medium runoff; moderately <br />permeable. <br />USE AND VEGETATION: The major use of this soil is for livestock grazing. The present <br />vegetation is blue grama, sideoats grama, New Mexico feathergrass, Indian ricegrass, <br />scattered oneseed juniper, and winterfat. <br />DISTRIBUTION AND EXTENT: West-central New Mexico, Northern Arizona, <br />southwestern Colorado and southern Utah. MLRA 36. The series is moderately <br />extensive. <br />MLRA OFFICE RESPONSIBLE: Phoenix, Arizona <br />(REVISED 9/99) <br />2.04.9-32 <br />
