<br />. of preferred species is maintained in the plant
<br />community.
<br />If the plant cover is disturbed, protection from erosion
<br />is needed. Loss of the surface layer results in a severe
<br />decrease in productivity and in the potential of the unit to
<br />produce plants suitable for grazing. Slope limits access
<br />by livestock and results in overgrazing of the less sloping
<br />areas.
<br />Management practices suitable for use on this unit are
<br />proper range use, deferred grazing, and rotation grazing.
<br />Livestock grazing should be managed to protect the unit
<br />from excessive erosion. Mechanical treatment is not
<br />practical because of the areas of Rock outcrop and the
<br />steepness of slope.
<br />This unit is poorly suited to windbreaks and
<br />environmental plantings. The main limitations of the
<br />Peetz soil are the high content of lime, moderate
<br />available water capacity, and steepness of slope.
<br />Supplemental irrigation may be needed when planting
<br />and during dry periods.
<br />This map unit is in capability subclass Vlls,
<br />nonirrigated, and in Gravel Breaks range site.
<br />54-Platner loam, 0 to 3 percent slopes. This deep,
<br />well drained soil is on smooth to slightly dissected plains
<br />and adjacent stream terraces. It formed in calcareous
<br />loamy alluvium.
<br />Typically, the surface layer is grayish brown loam 4
<br />inches thick. The subsoil is clay, clay loam, and silty clay
<br />• loam 20 inches thick. The substratum to a depth of 60
<br />inches or more is calcareous fine sandy loam and sandy
<br />loam.
<br />Included in this unit are small areas of Ascalon fine
<br />sandy loam, Manzanola clay loam, and Nunn clay loam.
<br />Also included are soils that have a fine sandy loam or
<br />sandy foam surface layer.
<br />Permeability of this Platner soil is slow. Available water
<br />capacity is high. Effective rooting depth is 60 inches or
<br />more. Runoff is slow, and the hazard of water erosion is
<br />slight. The hazard of soil blowing is moderate.
<br />This unit is used as nonirrigated cropland and
<br />rangeland. Winter wheat is the main crop.
<br />This unit is well suited to winter wheat, barley, oats,
<br />and sorghum. Low annual precipitation is the main
<br />limitation for the crops that can be grown on this unit.
<br />Because precipitation is not sufficient for annual
<br />cropping, a cropping system that includes small grain
<br />and summer fallow is most suitable. Precipitation usually
<br />is too low for crops on this unit to make efficient use of
<br />fertilizer.
<br />Maintaining crop residue on or near the surface
<br />reduces runoff, reduces soil blowing, and helps to
<br />maintain soil lilth and organic matter content. Stubble-
<br />mulch farming, stripcropping, and minimum tillage help to
<br />control erosion and conserve moisture. Terraces reduce
<br />runoff and the risk of erosion and help to conserve
<br />oisture.
<br />The potential plant community on this unit is mainly
<br />olue grama, western wheatgrass, sedges, and
<br />
<br />Soil surv~,
<br />buffalograss. The average annual production of air-dry
<br />vegetation ranges from 500 to 1.500 pounds.
<br />II the range is overgrazed, the proportion of preferred
<br />forage plants decreases and the proportion of less
<br />preferred forage plants increases. Therefore, I~vestock
<br />grazing should be managed so that the desired balance
<br />of preferred species is maintained in the plant
<br />community.
<br />Range seeding is suitable if the range is in poor
<br />condition. The plants selected for seeding should meet
<br />the seasonal requirements of livestock or wildlife, or
<br />both. Other management practices that are suitable for
<br />use on this unit are proper range use, deferred grazing,
<br />and rotation grazing. If the plant cover is disturbed,
<br />protection from soil blowing is needed. Loss of the
<br />surface layer results in a severe decrease in productivity
<br />and in the potential of the soil to produce plants suitable
<br />for grazing.
<br />This unit is well suited to windbreaks and
<br />environmental plantings. Supplemental irrigation may be
<br />needed when planting and during dry periods.
<br />This map unit is in capability subclass IV, nonirrigated,
<br />and in Loamy Plains range site.
<br />55-Renohill fine sandy loam, 0 to 6 percent
<br />slopes. This moderately deep, well drained soil is on
<br />slightly dissected to moderately dissected plains. It
<br />formed in calcareous loamy or clayey residuum derived
<br />dominantly from shale.
<br />Typically, the surface layer is brown fine sandy loam 5
<br />inches thick. The subsoil is clay foam 13 inches thick.
<br />The substratum is calcareous clay loam 14 inches thick.
<br />Shale is at a depth of 32 inches. Depth to shale ranges
<br />from 20 to 40 inches. In some areas the surface layer is
<br />loam or clay loam.
<br />Included in this unit are small areas of Midway clay
<br />loam, Shingle loam, and Rock outcrop o1 shale.
<br />Permeability of this Renohill soil is slow. Available
<br />water capacity is moderate. Effective rooting depth i5 20
<br />to 40 inches. Runoff is medium, and the hazard of water
<br />erosion is slight to moderate. The hazard of soil blowing
<br />is moderate.
<br />This unit is used as rangeland and nonirrigated
<br />cropland.
<br />The potential plant community on this unit is mainly
<br />blue grama, western wheatgrass, sedges, and
<br />buffalograss. The average annual production of air-dry
<br />vegetation ranges from 500 to 1,500 pounds.
<br />If the range is overgrazed, the proportion of preferred
<br />forage plants decreases and the proportion of less
