Truckton, and the Stapleton series. Each of these soils, especially the <br />• Bresser and Truckton soils, indicate sand deposits, but tend to be <br /> somewhat mare gravelly. None of these sails were found on this site. <br />It appears to be pure Blakeland loamy sand. <br />In most cases, the organic matter content is medium to low, erosion <br />hazard is low to nedium, but the wind-blowing hazard is rather high due <br />to the fine texture of the sail. The sand deposits found under the soil <br />were primarily derived from aeolian sources, sa the hazard from wind <br />erasion is quite understandable. <br />This sail provides excellent sites for building as it does not have <br />any appreciable shrink-swell characteristics. In same places it is used <br />for rangeland, but its productivity is law and its need for intensive <br />management is rather great. <br />The usual native vegetation is dominated by western wheatgrass, <br />• side-oats grams, and needle and thread. However, few areas exist that <br />still have the "native" vegetation. Most areas where range uses were <br />predoninant in the past were interseeded in order to increase <br />production. Also, even short-term overgrazing greatly alters the <br />composition. Farming is possible on this soil, but because of its <br />porosity very intensive irrigation is needed and even then it does not <br />produce well. Trees can 6e grown near irrigation ditches and water <br />hales, but without a ready supply of water, tree survival is very low. <br />On the whale, uses other than urban construction or marginal rangeland <br />are simply not cast effective. <br />• <br />F'AGE .?
