• Using Sodium Carbonate to Seal Leaky Stock Ponds in Eastern Montana

      Neff, E. L. (Society for Range Management, 1980-07-01)
      Mixing sodium carbonate into the top 100 to 150 mm of soil in three farm ponds constructed in calcareous soil in eastern Montana effectively reduced seepage losses for about 3 years following treatment. Seepage rates the first year after treatment were decreased to 20 to 40% of the pretreatment rate, but they were 60 to 100% of the pretreatment rate 4 years after treatment.
    • Vivipary, Proliferation, and Phyllody in Grasses

      Beetle, A. A. (Society for Range Management, 1980-07-01)
      Some temperate grasses have the ability to produce in their inflorescence modified spikelet structures that act to reproduce the species vegetatively. These types may be either genetically fixed or an occasional expression of environmental change.
