• Atrazine Residue and Seedling Establishment in Furrows

      Eckert, R. E. (Society for Range Management, 1974-01-01)
      Deep furrows made with shovel openers and simulated disk-type furrows were evaluated for removal of atrazine residue from the seeded row and for seedling establishment in the atrazine-fallow technique of range seeding. Atrazine residue in all furrow treatments was below the toxic level for crested and intermediate wheatgrasses. Established stands of both species were similar in all furrow treatments. Therefore, the deep-furrow rangeland drill with disk openers appears suited for large-scale application of the atrazine-fallow technique.
    • Asphalt-Fiberglass for Precipitation Catchments

      Myers, L. E.; Frasier, G. W. (Society for Range Management, 1974-01-01)
      Field experience gained in the construction of nine water harvesting catchments since 1962 has shown that field-fabricated asphalt-fiberglass coverings are a dependable means of providing water for livestock on many rangeland areas. Initial construction costs, including site preparation and labor, were less than $1.25 per square yard. The asphalt-fiberglass coverings are easy to install, require no sophisticated equipment or skills, and are highly resistant to mechanical damage to wind or animals.
