• Aspen Regrowth in Pastures of the Peace River Region

      Pringle, W. L.; Elliott, C. R.; Dobb, J. L. (Society for Range Management, 1973-07-01)
      Low-cost methods are required for converting wooded areas of Canada's Peace River region to productive pasture. Methods of circumventing the costly procedures of breaking the soil and removing roots preparatory to seeding were investigated. Various tillage implements (mouldboard plow, Rome disc-at 3 depths, rotovator, one-way disc, and tandem disc) were compared as to effectiveness for seed-bed preparation. In addition, seed was both drilled and broadcast. Forage yields varied greatly, from an average of 1,184 lb/acre on the plowed plots to 103 lb on the check area. It was concluded that all methods tried tend to enhance tree establishment. Because of this, none of the methods tested would bring about an economically viable pasture.
    • AID's Interest in Range Management and Livestock Production in te Tropics and Subtropics

      Kelley, O. J. (Society for Range Management, 1973-07-01)
      Grassland resources in the tropics and subtropics of South America, Asia, and Africa occupy nearly one billion hectares of land, roughly twice as great as all arable lands in these areas. These support about four billion sheep units of ruminant livestock. One major hope for more nearly meeting animal protein needs for peoples of the tropics and subtropics is by increasing supplies of meat from ruminants grown on permanent grasslands in four ecological zones-humid tropics, savannas, sahelians, and semidesert. The five major categories of limiting factors that control progress in livestock production on rangelands are (1) feed supplies and animal nutrition, (2) animal disease control and prevention, (3) livestock husbandry and management, (4) animal breeding, and (5) efficient marketing systems. A "Range Code," consisting of 12 principles, is presented to evaluate similarities and differences between the tropics and temperate zones. Group action by "associations" of pastoral groups is suggested as a method of improving the potential for more efficient livestock production and marketing without disturbing private ownership of livestock.

    • 'Horizontal’ Wells

      Welchert, W. T.; Freeman, B. N. (Society for Range Management, 1973-07-01)
      Forty-five horizontal wells were constructed on the San Carlos Apache Indian Reservation during 1967-69. This paper describes site selection, drilling equipment, and the construction process and lists the advantages of the horizontal well system over more conventional systems.
