The Effects of Burning on Mineral Contents of Flint Hill Range ForagesUmoh, J. E.; Harbers, L. H.; Smith, E. F. (Society for Range Management, 1982-03-01)The mineral status of Flint Hills bluestem forage was assessed monthly between 1975 and 1976. Results indicated that magnesium, potassium, and manganese were adequate for optimum performance of range cattle during spring and summer, but that magnesium and potassium were low in late fall and winter. Concentrations of calcium, iron, and zinc, highest in spring, were higher throughout the year than established nutrient requirements. Burning significantly decreased phosphorus and iron and increased magnesium. The low levels of phosphorus and potassium during fall and winter do not affect animal performance.
