• Nitrates in South Dakota Range Soils

      White, E. M.; Moore, D. G. (Society for Range Management, 1972-01-01)
      The nitrate contents and distributions were found to be similar in some South Dakota range soils with and without alfalfa and from over-grazed and lightly grazed range. Less than 3 ppm NO3- N was found except for 8 ppm in shale substrata below the normal depth of moisture penetration.
    • One-Square-Meter Method

      Ibrahim, K. M. (Society for Range Management, 1972-01-01)
      One-square-meter frame was developed to estimate directly percent cover of vegetation. It is well adapted to semi-desert grassland and desert shrub types where vegetation cover does not exceed 100 percent. The device provides accuracy of estimates and saves recording time.

    • Organic Matter, N, and Base Accumulation Under Pensacola Bahiagrass

      Beaty, E. R.; Tan, K. H. (Society for Range Management, 1972-01-01)
      A deep and unfertile sandy soil in the Georgia Coastal Plain from which the top soil had been removed was seeded to Pensacola bahiagrass in 1967 and allowed to grow until 1970. No harvests were made, and no fertilizer was applied. When sampled in 1970, the plots under grass contained 23.1% more N than did fallow plots. The soil organic matter content to 12 inches deep in the soil profile had more than doubled under the sod, and bases had been accumulated in the soil surface under sod but were concentrated lower in the soil profile under fallow.
    • Optimum Temperatures for Germination of Winterfat

      Springfield, H. W. (Society for Range Management, 1972-01-01)
      Seeds of winterfat (Eurotia lanata) collected four consecutive years at a site in central New Mexico were tested at temperatures from 33 to 110 F. Optimum temperatures for germination were 50 to 80 F. Germination was practically complete within 5 days at 59 F or higher.
