IFFERENT species of grass grown on the same soil may differ -D significantly in chemical composition (I , 3, 6) .3 Appreciable differences in chemical composition are of practical importance, since they determine to a considerable degree the feeding qualities of the forage. They are of especial importance in the consideration of species of grass for the reseeding or improvement of depleted ranges. A given species may be a good one because of type of growth, ease of establishment or maintenance under range conditions, or palatability, but a poor species on account of chemical composition. For example, angleton grass, Andropogon annulatus, possesses some highly desirable characteristics (5) but is sometimes low in protein and phosphoric acid as compared with other species (7). A study of the comparative chemical composition of different species of grasses grown on the same soil was therefore considered desirable. Under ordinary range conditions, such a study is limited by the comparatively few species found on a given area. An opportunity to study the chemical composition of a large number of species grown on the same soil and under uniform conditions was afforded by nursery plantings made near San Antonio, Texas, by the Nursery Division of the Soil Conservation Service, U. S. Dept. of Agriculture.
