H. Rate of increase in yield of crested wheatgrass following use of herbicide on associated sagebrush was measured over four years, including the year of treatment. Significant increases in yield, which were probably worthwhile economically, did not begin until the third year after spraying. 1969-07-01T00:00:00Z http://hdl.handle.net/10150/649982 Water Use, Adaptability, and Chemical Composition of Grasses Seeded at High Elevations Tew, R. K. Soil moisture depletion varied directly with extent of top and root growth of five grass species seeded on four areas between 6,500 and 8,500 ft in northern Utah. Smooth bromegrass and intermediate wheatgrass had greater root and top growth and used the most moisture at the lower elevation site where temperatures were highest, but timothy and orchardgrass grew best at higher elevations. Timothy contained low levels of nitrogen, phosphorus, and potassium on all sites, whereas tall oatgrass and orchardgrass contained high levels. 1969-07-01T00:00:00Z http://hdl.handle.net/10150/649980 Water Control by Rangeland Management Biswell, H. H. In rangeland management, water quantity and quality are related to range condition. The better the range condition, the better the water relationships. Range condition can be improved by regulating grazing, reseeding, fertilizing, type conversions, and contour furrowing and pitting. Rangelands are highly variable in nearly every respect. The range manager must understand the climatic/topographic/soil/plant/animal/water relationships for the areas under his control; he must have sound management objectives; and he must be willing to work toward those objectives in so far as is economically feasible. 1969-07-01T00:00:00Z
