Continued <br />• Baca Loam <br />Fertilizer is needed to insure optimum growth of grasses and legumes. <br />If properly managed, this unit can produce 4.5 tons of irrigated grass <br />or alfalfa hay per acre. <br />In areas of nonirrigated cropland, control of soil blowing and <br />conservation of moisture are important concerns. Because precipitation <br />is not sufficient for annual cropping, a cropping system that includes <br />small grain and summer fallow is most suitable. Crop residue left on or <br />near the surface helps to conserve moisture, maintain filth, and control <br />erosion. Soil blowing can be reduced by planting crops in alternate <br />strips at right angles to the prevalling wind. Excessive cultivation <br />can result in the formation of a tillage pan. This pan can be broken by <br />subsoiling when the soil is dry. With good management, this unit can <br />• produce 15 bushels per acre of wheat grown in a wheat-fallow cropping <br />system. <br />This unit is well suited to windbreaks and environmental plantings. The <br />hazard of soil blowing can be reduced by cultivating only in the tree <br />rows and by leaving a strip of vegetation between the rows. <br />Supplemental irrigation may be needed when planting and during dry <br />periods. Among the trees that are suitable for planting are <br />Russian-olive and Rocky Mountain juniper. Among the shrubs are plum and <br />lilac. <br />If this unit is used for homesite development, the main limitation is <br />moderate shrink-swell potential. The effects of shrinking and swelling <br />can be reduced by maintaining constant moisture content around the <br />foundation, Backfilling, with material that has low shrink-swell <br />potential can also reduce the effects of shrinking and swelling. <br />Absorption lines should be placed below the moderately <br />• <br />
