Photograph of a heavily timbered area that was in poor range condition. Early June 1955 tow pounds of Kuron (propionic acid) per acre was applied by aero plane. All vegetative growth of shrubs and trees was controlled on 90 % of the shrubs and trees. A definitive percentage of tree kill could not be determined at this time but a tremendous growth of primarily little bluestem can be observed even directly underneath the trees. An excellent seed crop was produced by this area which was completely deferred from grazing during 1955. Soil Unit 12-RP is the prevailing soil type.

Photograph of Claud Leonard, Work Unit Conservationist [WUC], Rush Springs, Oklahoma, observing the dead timber from the effects of spray material. This heavily timbered area was in poor range condition. In early June, 1955, two pounds of Kuron (Propionic acid) per acre was applied by airplane reducing the vegetative growth of shrubs and trees by 90%. A definite percentage of tree kill could not be determined at this time but a tremendous growth of primarily Little Bluestem can be observed even directly underneath the trees. An excellent seed crop was produced in this area which was completely deferred from grazing during 1955. For the “before” treatment picture, refer to OK-12-1. Soil Unit 12-RP is the prevailing soil type.
