• Controlling Prairie Threeawn (Aristida oligantha Michx.) in Central and Eastern Kansas with Fall Burning

      Owensby, C. E.; Launchbaugh, J. L. (Society for Range Management, 1977-09-01)
      Prairie threeawn, an annual, weedy grass of little or no grazing value, was controlled effectively by fall burning. Burning on dates later than early December gave no control. Mowing and raking gave some control, so mulch removal appeared to be the primary causal factor in control. Seeding native grasses on abandoned fields infested with prairie threeawn after fall burning gave excellent stands, but subsequent winter heaving reduced the stands.
