THIS paper presents experimental results of one form of rotation grazing on the semi-arid native rangeland of the southern Great Plains. The studies were conducted by the Bureau of Plant Industry, Soils, and Agricultural Engineering, Agricultural Research Administration, U. S. Department of Agriculture, in cooperation with the Oklahoma Agricultural Experiment Station, Bureau of Animal Industry, and other agencies. During the growing season, the animals were rotated at regular or irregular intervals on two or three divisions of a dryland, native range. This rotation plan will be referred to as "divisional rotation." To prove its advantages over continuous grazing it must show superiority at the same stocking rate; otherwise results could be confused with a study of rate of stocking. |
