L. W. Greene, P. F. Hardt, D. B. Herd

Abstract


This project was conducted to compile mineral composition of Bermudagrass and native forage samples analyzed by the Texas A&M University Extension Soil, Water, and Forage Testing Laboratory.
Approximately 12,000 forage samples originating from either Bermuagrass or native pastures over a five-year period were analyzed for potassium (K), calcium (Ca), phosphorus (P), magnesium (Mg), sulfur (S), copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) content. Fertilization and other forage management practices pertaining to the samples are not known. The data suggest a widespread occurence of deficient levels of plant phosphorus, copper, and zinc for beef cattle grazing Texas forages. ...
