In Utah reaction ranges to strongly alkaline. <br />A horizon <br />Hue: 2.5YR to l OYR <br />Value: 5 to 7 dry, 3 to 6 moist <br />Chroma: 2 to 6 <br />Texture: Sandy loam, gravelly sandy loam, fine sandy loam, channery fine sandy loam, very fine sandy loam, <br />loam, or gravelly loam <br />Bw horizon (where present) <br />Hue: 5YR, 7.5YR, or l OYR <br />Value: 4 to 6 dry, 3 to 5 moist <br />Chroma: 2 to 4 <br />Texture: fine sandy loam, loam, sandy clay loam, or clay loam <br />Bk horizon <br />Hue: 2.5YR to l OYR <br />Value: 5 to 8 dry, 4 to 7 moist <br />Chroma: 0 to 6 <br />Texture: Sandy loam, fine sandy loam, loam, sandy clay loam, or clay loam <br />Calcium carbonate equivalent: 15 to 40 percent <br />In some pedons textures of gravelly sandy loam or gravelly sandy clay loam occur. <br />COMPETING SERIES: These are the A ra on (UT), Anasazi (UT), Chroder (CO), Ch=city (T WY), <br />Ch Wade r (NM), Cobb r (T UT), Milok (UT), M' ' a (UT), NNal (NM), Sazi (UT), and Yattle (CO). <br />Abracon, Chr r, and oC bbra soils have soil moisture control sections that receive loss precipitation in May <br />and June. Anasazi. C ci , Ch <br />Wade and Sazi soils are moderately deep. Chroder, Milok, Mivida and <br />Yattle soils have loss than 18 percent clay in the particle -size control section Nala sods have more than 15% <br />rock fragments in the particle -size control section. <br />GEOGRAPHIC SETTING: Harvey soils are on hills, swales, plateaus, bajadas, mesas, and fan piedmonts. <br />Slope gradients range from 0 to 15 percent. Mean annual precipitation typically ranges from 10 to 14 inches with <br />a summer maximum. In some areas the series has ranged to 16 inches ofprecipitation. In Utah the annual <br />precipitation ranges as low as 8 inches. Mean annual temperature ranges from 47 to 57 degrees F. The frost -free <br />period ranges from 120 to 190 days and elevation ranges from 4,700 to 7,800 feet. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Clapper, Demon, Ildefonso, Korman, anzano, <br />Neesopah, Nepesta, PiW_nn, Rocky Ford and Witt soils. Clapper and Ildeforlso soils have a skeletal control <br />section. Dean soils have carbonatic mineralogy. Korman soils have a coarse -loamy control section. Manzano <br />soils have a mollic epipedon. Neesopah, Nepesta and Witt soils have an argillic horizon Pinon sods have <br />https: / /soilseries.sc.eg ov usda.g oJOSD_Does /H/HARVEY.html 213 <br />
