Show PART II NATURE, USE AND MANAGEMENT OF WATERSHED LAND Shallow soil over weathered granite Wind erosion is of major significance on sandy soils in the arid parts of the region where vegetal cover is sparse. Dominantly, soils affected by wind removal and deposition are most extensive at elevations below 7,000 feet. Salinity and high exchangeable sodium are unfavorable soil charac- teristics in the more arid parts of the region. They limit the opportunity for revegetation for watershed protection. Injurious accumulations of soluble salts restrict the choice of plants and decrease yields. Where reclamation measures are not feasible, changes in land use may be required. High exchangeable sodium produces unfavorable physical soil conditions for plant growth and may actually cause plant injury. Affected soils in residuum and alluvium from saline and highly alkaline shales are widely scattered within the region, however, the largest acreages are in the lower valleys and along drainageways. Water table or wetness limits rooting depth and determines plant adaptation. High ground water tables account for much of the salt accumulation in soils. Distribution of soils with high ground water tables closely follows that of saline soils except for wet soils in the mountains. 10 |
