Huerfano County Area, Colorado
<br />Woodland products such as firewood and pinyon nuts
<br />are available on this unit. The stands of pinyon and
<br />juniper, however, commonly are sparse.
<br />If this unit is used for homesite development, the main
<br />limitations are moderate depth to bedrock in the
<br />Progresso soil and steepness of slope. Areas where
<br />there is a dense stand of pinyon and juniper trees are
<br />moderately deep to sandstone.
<br />This map unit is in capability subclass Vle,
<br />nonirrigated. About 50 percent of the unit is in Loamy
<br />Foothills range site, and 50 percent is in Pinyon-Juniper
<br />woodland site.
<br />62-Otero sandy loam, 1 to 9 percent slopes. This
<br />deep, somewhat excessively drained soil is on uplands
<br />with low dunelike relief. It formed in eolian sand. The
<br />native vegetation is mainly grass. Elevation is 5,500 to
<br />6,300 feet. The average annual precipitation is 11 to 15
<br />inches, the average annual air temperature is 50 to 54
<br />degrees F, and the average frost-free period is 135 to
<br />165 days.
<br />Typically, the surface layer is light brownish gray sandy
<br />loam about 7 inches thick. The substratum to a depth of
<br />60 inches or more is sandy loam. The soil is mildly
<br />alkaline to a depth of 7 inches and moderately alkaline
<br />below that depth.
<br />Included in this unit is about 20 percent Kim fine sandy
<br />am in concave areas. Also included are small areas of
<br />~Iney sandy loam in narrow drainageways.
<br />Permeability of this Otero soil is moderately rapid.
<br />Available water capacity is moderate. Effective rooting
<br />depth is 60 inches or more. Runoff is slow to medium,
<br />and the hazard of water erosion is slight to very high.
<br />The hazard of soil blowing is high.
<br />This unit is used as rangeland.
<br />The potential plant community on this unit is mainly
<br />sideoats grama, needleandthread, and little bluestem.
<br />Other grasses that characterize the unit are Indian
<br />ricegrass, blue grama, and thickspike wheatgrass. The
<br />average annual production of air-dry vegetation is about
<br />1,400 pounds per acre. If the condition of the range
<br />deteriorates, threeawn, snakeweed, sand dropseed,
<br />yucca, and rabbitbrush increase. Range seeding is
<br />suitable if the range is in poor condition.
<br />If this unit is used for windbreaks and environmental
<br />plantings, the main limitations are the droughtiness of
<br />the soil and the hazard of soil blowing in disturbed areas.
<br />This unit is well suited to homesite development.
<br />Revegetating disturbed areas around construction sites
<br />as soon as possible helps to control soil blowing.
<br />This map unit is in capability subclass Vle,
<br />nonirrigated. It is in Sandy Plains range site.
<br />63-Otero fine sandy loam, 1 to 9 percent slopes.
<br />This deep, somewhat excessively drained soil is on foot
<br />~opes and uplands. It formed in alluvium and eolian
<br />nd. The native vegetation is mainly grass. Elevation is
<br />6,300 to 7,500 feet. The average annual precipitation is
<br />49
<br />12 to 15 inches, the average annual air temperature is
<br />48 to 52 degrees F, and the average frost-free period is
<br />100 to 130 days.
<br />Typically, the surface layer is light brownish gray sandy
<br />loam about 6 inches thick, The substratum to a depth.of
<br />60 inches or more is sandy loam. The soil is mildly
<br />alkaline to a depth of 6 inches and moderately alkaline
<br />below that depth.
<br />Included in this unit is about 20 percent Kim fine sandy
<br />loam in areas between low, dunelike ridges. Also
<br />included are small areas of Olney sandy loam in
<br />drainageways.
<br />Permeability of this Otero soil is moderately rapid.
<br />Available water capacity is moderate. Effective rooting
<br />depth is 60 inches or more. Runoff is slow to medium,
<br />and the hazard of water erosion is slight to very high.
<br />The hazard of soil blowing is high.
<br />This unit is used as rangeland.
<br />The potential plant community on this unit is mainly big
<br />bluestem, little bluestem, and sand reedgrass. Other.
<br />grasses that characterize the unit are blue grama,
<br />sideoats grama, needleandthread, and western
<br />wheatgrass. The average annual production of air-dry
<br />vegetation is about 1,100 pounds per acre. If the
<br />condition of the range deteriorates, blue grama,
<br />threeawn, snakeweed, yucca, and rabbitbrush increase.
<br />Range seeding is suitable if the range is in poor
<br />condition.
<br />If this unit is used for windbreaks and environmental
<br />plantings, the main limitations are the droughtiness of
<br />the soil and the hazard of soil blowing in disturbed areas.
<br />This unit is well suited to homesite development.
<br />Revegetating disturbed areas around construction sites
<br />as soon as possible helps to control soil blowing.
<br />This map unit is in capability subclass Vle,
<br />nonirrigated. It is in Sandy Foothills range site.
<br />64-Patent loam, 2 to 8 percent slopes. This deep,
<br />Well drained soil is on fans and foot slopes and in
<br />swales. It formed in alluvium derived dominantly from
<br />sandstone, siltstone, and shale. The native vegetation is
<br />mainly grass. Elevation is 7,700 to 8,200 feet. The
<br />average annual precipitation is 12 to 16 inches, the.
<br />average annual air temperature is 42 to 46 degrees F,
<br />and the average frost-free period is 80 to 110 days.
<br />Typically, the surface layer is brown loam about 2
<br />inches thick. Below this to a depth of 60 inches or more
<br />is loam. The soil is moderately alkaline throughout.
<br />Included in this unit is about 5 percent Brownsto very
<br />gravelly loam, commonly under scattered pinyon and . .
<br />juniper trees.
<br />Permeability of this Patent soil is moderate. Available
<br />water capacity is high. Effective rooting depth is 60
<br />inches or more. Runoff is medium, and the hazard of
<br />water erosion is moderate to very high.
<br />This unit is used as rangeland and irrigated cropland.
<br />Hay and pasture are the main irrigated crops. Irrigated
<br />oats is also grown in a few areas. In years when
