More land in the United States is used for grazing and hay production than for all other farm crops grown. Well-managed pastures and rangeland have always been recognized as an economical source of feed and recently have commanded much attention as an effective means of conserving soil resources and preventing erosion. In the states if North and South Dakota, Nebraska, Colorado, Wyoming and Montana, about 67 per cent of the total land in farms and ranches is in pasture and hay. Over 60 per cent of the entire area of South Dakota and about 83 per cent of the area west of the Missouri River is devoted to range land. Seventy-five to 95 percent of the total feed needed by cattle and sheep in the six states listed above is furnished by pasture and roughage which cannot be utilized directly for human consumption. Present emphasis on soil conservation stresses the need for increased acreages of grasses for maintenance of soil fertility and prevention of soil erosion. With the increased demand for meat and food, and the conservation of our resources it is imperative that more complete and more accurate information be secured on the actual nutritive value of the native grasses of this area.
