Nutrient content of native grasses on sandy and red sandy loam range sites in south texas usa

, : Nutrient content of native grasses on sandy and red sandy loam range sites in south texas usa. U S Department of Agriculture Science & Education Administration Agricultural Research Results ARR-S (7): 1-30

The effects of season and precipitation on the crude protein, P, Ca, Mg, Na and K contents of native range grasses from sandy and red sandy loam range sites were determined and these data were used to determine the critical periods of protein and mineral deficiency in beef cattle. Grasses were sampled monthly from Sept. 1975-Aug. 1977; 15 grasses from the sandy site and 6 from the red sandy loam site. Livestock grazing the grasses from either site would probably need supplemental feeding of protein and K from Dec. through Feb. or early March. Year-round supplemental feeding of P, Mg and Na would be recommended on both sites.
