Florida's soils are low in nutrients, which is reflected in the low mineral content of range forages. This investigation was designed to determine the contents of P, K, Ca, Mg, Fe, Mn, Zn, and Cu and the Ca: P ratio in creeping bluestem (Schizachyrium stoloniferum Nash.), a widespread, high-yielding native forage. The grass was cut at 10 and 20-cm heights during 70-day intervals from June to October 1976, August to December 1976, and October 1976 to February 1977. Height of cut did not have significant effect on mineral contents, but strong seasonal patterns occurred. Based on whole plant samples, the contents of K, Mg, P, Zn, and Cu and the Ca: P ratio were inadequate when compared to National Research Council requirements for dry, pregnant cows, but Ca, Fe and Mn may be adequate in the forage.
