The mineral structure and its dynamics in forest ecosystems have been undertaken by a number of workers. Such studies are meagre for tropical grassland. The purpose of this study was to ascertain the nutrient structure for the producer components, and to estimate the annual uptake, retention and release for N, P, K and Ca. Data for these elements are given for plant and soil. The soil contains many more times nutrient than held by plant biomass. Inventory of the minerals indicates that, of the four elements i.e. N, P, K and Ca studied, annually about 58, 16, 18 and 38 kg/ha, respectively are taken up by the grassland, of which 29, 7, 6 and 23 kg/ha are released and about 29, 9, 12 and 14 kg/ha are retained in the vegetation compartments.
