<br />Pokeman, Potts, Pugsley, Scholle, Spenlo, Stoneham, Tapia, Toluca, Tuweep, and Yenlo soils lack
<br />lithic contacts within depths of 40 inches. Cushman and Hagerman soils lack a calcic horizon below the
<br />argillic horizon. Fattig soils have chroma of 1 in the Bt horizon. Flaco soils have mean annual soil
<br />temperatures greater than 52 degrees F. Gapbutte soils have less than 15 percent calcium carbonate
<br />equivalent. Spangler soils have a paralithic contact above depths of 40 inches. Sundance soils have
<br />lithologic discontinuities. Threetop soils have soil moisture control sections that are moist in some or all
<br />parts in May and June.
<br />GEOGRAPHIC SETTING: Progresso soils are on old terraces, benches, mesas, and upland hills and
<br />ridges. The soil formed in alluvium derived from sandstone or limestone. Slopes range from 0 to 15
<br />percent. Elevation ranges from 5,300 to 6,800 feet. The mean annual precipitation ranges from 12 to
<br />15 inches. Mean annual air temperature ranges from 45 to 49 degrees F. In Arizona mean annual air
<br />temperatures reach 57 degrees F., mean annual precipitation is as low as 10 inches, and the frost-free
<br />period extends to 165 days. The average frost-free period ranges from 90 to 130 days.
<br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the competing Barx soils and the Pinon soils.
<br />Pinon soils have hard bedrock at depths above 20 inches.
<br />DRAINAGE AND PERMEABILITY: Well drained; slow to medium runoff; moderate permeability.
<br />USE AND VEGETATION: This soil is used mainly for rangeland. A few areas are irrigated and produce
<br />corn for silage, small grains, alfalfa, and grass hay. Native vegetation consists mainly of galleta, Indian
<br />ricegrass, need leandthread, and Wyoming big sage.
<br />DISTRIBUTION AND EXTENT: Western Colorado, northern Arizona and adjacent parts of New
<br />Mexico. The series is of moderate extent.
<br />SERIES ESTABLISHED: Reconnaissance Upper Rio Puerco, New Mexico, Soil Conservation Service,
<br />1940.
