<br />79-Otero randy loam, S to 9 percent doper. This
<br />strongly sloping soil is on uplands and fans.
<br />Included with this soil in mapping are small areas
<br />of soils that are more eloping or leas sloping. Also
<br />included are a few small areas of Nelson, Kim, and
<br />Tassel soils.
<br />Runoff is rapid, and the hazard of erosion is severe.
<br />If irrigated, this soil is well suited to pasture and,
<br />to a lesser extent, wheat, barley, or alfalfa. Under
<br />dryland management it is suited to pasture or native
<br />grasses. Capability unite IVe-2, irrigated, and VIe-2,
<br />dryland; Sandy Plains range site; windbreak auit•
<br />ability group 2.
<br />80-Otero•Nelron sandy loam, 3 to 25 percent
<br />eloper. This wmplax consists of gently sloping to mod-
<br />erately steep soils on uplands. It is about 60 percent
<br />Otero sandy loam and S6 percent Nelson sandy loam.
<br />Otero sandy loam ie less eloping at the top and near
<br />the base of the slope, and Nelson sandy loam is steeper.
<br />The Otero soil has the profile described as representa-
<br />tive of the Otero aeries. The Nelson soil has a profile
<br />similar to the one described as representative of the
<br />Nelson series, but the surface layer is sandy loam.
<br />Included with these soils in mapping are about 16
<br />percent areas of Tassel soils and Rock outcrop.
<br />Runoff is medium to rapid, sad the hazard of erosion
<br />ie severe.
<br />These soils are suited to pasture or native grasses.

<br />site; windbreak suitability group 8.
<br />Paoli Series
<br />The Paoli aeries consists of deep, well drained soils
<br />that Formed in alluvium. These soils are on terraces
<br />and bottom lands. Elevation ranges from 4,800 to
<br />6,800 lest. Slopes are 0 to 1 percent. The native
<br />vegetation is blue grams, bluestema, needlegrass, and
<br />some forba and shrubs. Mean annual precipitation
<br />ranges from 18 to lb inches, mean annual air tempera-
<br />ture ranges from 48° to 60° F, and the frost-free
<br />season ranges from 136 to 160 days.
<br />In a representative profile the surface layer is dark
<br />grayish brown fine sandy loam about 42 inches thick.
<br />The underlying material is brown fine sandy loam:
<br />Permeability is moderately rapid, and the available
<br />water capacity is high. Reaction is mildly alkaline
<br />above a depth of 22 mches and moderately alkaline
<br />below that depth.
<br />These soils are used mainly for irrigated trope. Some
<br />areas are in native grass.
