    • Adaptation of Distance Measurements For Range Sampling

      Laycock, W. A. (Society for Range Management, 1965-07-01)
      Modification of a distance measurement technique (the angle-order method) for estimating density, herbage production, and ground cover was tested in 1960 and 1961 at the U. S. Sheep Experiment Station in Idaho. Estimates of plant density and herbage production obtained by the angle-order method were compared with estimates on 9.6- and 96-squarefoot plots, and estimates of cover were compared with estimates from line intercepts on 10-meter lines. Several limitations inherent in use of the angle-order method render it unsuitable for sampling complete plant communities of sagebrush-grass rangeland, but it may be used efficiently for estimating density, production, and ground cover for one or two key species.
    • Control of Russian Olive by Aerial Applications of Herbicides

      Bovey, R. W. (Society for Range Management, 1965-07-01)
      Russian olive trees in Nebraska were controlled with aerial application of 1:1 mixture of PGBE esters of 2,4-D and 2,4,5-T. Repeat application after one or two years was needed for best control of large trees.
    • Determining Common Use Grazing Capacities by Application of the Key Species Concept

      Smith, A. D. (Society for Range Management, 1965-07-01)
      Correct substitution rates of one grazing animal for another under common use take place at uniform rates, being governed at any point by the utilization standard of some single species. The capacity under common use may be greater than that realized with the less suited animal alone, or greater than either animal alone, depending upon the particular combination of animal numbers and the particular range.
    • Effects of Periodic Clipping On Yield Of Some Common Browse Species

      Lay, D. W. (Society for Range Management, 1965-07-01)
      Of six browse species clipped annually for 10 years, some maintained production under 50 percent clipping better than others with 25 percent clipping. Optimum appeared to be closer to 25 percent. Under destructive 100 percent monthly clipping of 16 species, the smilaxes, gallberry, and American cyrilla were most tenacious. All plants were in pine forest understory.
    • Effects Of Seeding And Grazing On Infiltration Capacity And Soil Stability Of A Subalpine Range In Central Utah

      Meeuwig, R. O. (Society for Range Management, 1965-07-01)
      Seven years after disking and seeding to grass, main effects were: decreased organic matter and capillary porosity in the surface soil, greater soil bulk density, and decreased plant and litter cover. Seeding did not significantly affect infiltration or soil stability. Grazing during the previous four years decreased plant and litter cover and noncapillary soil porosity, but increased capillary porosity in the surface soil and decreased infiltration and soil stability.
    • Effects of Spring Burning on Yields of Brush Prairie Savanna

      Vogl, R. J. (Society for Range Management, 1965-07-01)
      Herbage production the first season after burning was 2,110 lbs. per acre, as compared to 772 lbs. on unburned areas. Burned areas maintained high productivity of grasses and forbs the second year. Dead material comprised about 90% of the total herbage for stands unburned for 25 years, but only 19% on burned stands.
    • Estimating Browse from Twig and Stem Measurements

      Schuster, Joseph L. (Society for Range Management, 1965-07-01)
      In upland forests of east Texas, total twig length was closely correlated with yield of deer browse plants, but the best predictor of yields was a combination of twig numbers and length.
    • Herbage Production On a Gambel Oak Range in Southwestern Colorado

      Jefferies, N. W. (Society for Range Management, 1965-07-01)
      Herbage production and regrowth following grazing were greater in openings than under oaks. Soil moisture was greater under the oaks throughout the season.
    • How the Livestock Industry Can Best Be Served by Livestock Publications

      Chohlis, J. (Society for Range Management, 1965-07-01)
    • Management of Sown And Natural Lovegrass

      Davidson, R. L. (Society for Range Management, 1965-07-01)
      In South Africa lovegrass yields liveweight cattle gains around 375 lb./acre, and it is easily managed by very heavy and continuous grazing during the growing period. Fertilizer boosts production, but is not essential on grazed pasture. For reclamation of rangeland the chloromelas type appears more aggressive than the coarser curvula and robusta types. Feeding value of lovegrass hay is at least equal to that of teff hay.
    • Properties of Saline Range Soils of the Rio Grande Plain

      Fanning, C. D.; Thompson, C. M.; Issacs, D. (Society for Range Management, 1965-07-01)
      Range conditions on saline soils are poor as a result of overgrazing. Reseeding plans need to consider species and drought-inducing effects of excess salts. Soil properties suggest that proper vegetative cover would enhance salt removal.
    • Range Management Pays at the Scales

      Ross, Robert L. (Society for Range Management, 1965-07-01)
    • Reseeding "Go-Back" Land in the Flint Hills of Kansas

      Owensby, Clenton E.; Anderson, Kling L. (Society for Range Management, 1965-07-01)
      Three sorghum types were compared as mulches for seeding 12 native species and varieties in "go-back" land in the Kansas Flint Hills. Significant differences in seedling establishment were found among the species and varieties, but type of sorghum mulch had no effect.
    • Response of Major Plant Species to Elk and Cattle Grazing in Northwester Wyoming

      Jones, Webster B. (Society for Range Management, 1965-07-01)
      Grazed elk ranges differ from grazed cattle ranges. Composition changes were detected for 18 plant species occurring on both types of range.
    • Shade Effects on Chemical Composition of Herbage in the Black Hills

      McEwen, L. C.; Dietz, D. R. (Society for Range Management, 1965-07-01)
      Kentucky bluegrass and some associated species contained more nitrogen-free extract and less crude fiber, calcium, and phosphorus when growing on open meadow sites than when growing on pine-shaded sites. During early development, plants growing on soils derived from limestone had a higher crude protein content than plants growing on soils developed from metamorphic parent materials.
