<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 />COMPETING SERIES: These are the Abracon (UT), Anasazi (U l), Chroder (CO), Ch=ci (T WY),
<br />ChWadera (NM), Cobb ra (T UT), Milok (UT), Mivida (UT), Na (NM), Sazi (UT), and Yattle (CO).
<br />Abracon, Chroder, and Cobbra soils have soil moisture control sections that receive less precipitation in May
<br />and June. Anasaz4 Chu i h adera, and S soils are moderately deep. Chroder, Milok, Mivida and
<br />Yattle soils have less than 18 percent clay in the particle-size control section. Nala soils 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 maxim m In some areas the series has ranged to 16 inches ofprecipitatior.L 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, Dean, Ildefonso, Korman, Manzano,
<br />Neesopah, Nepesta, Pinon, Rockv Ford and Witt soils. Clapper and Ildefonso 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 soils have
