Description: The productivity of different useful tropical plants is compared with respect to their biomass production. Furthermore, analyses of nutrient contents serve to explain the interrelationship between nutrient supply and primary production. The biomass and nutrient contents from three to six month old plants from Bertholletia excelsia H.B.K. (castanha-do-Brasil), Cedrela odorata L. (cedro vermelho), Dipteryx alata (cumaru), Theobroma grandiflorum (Spreng.) K. Schum. (cupuacu), Elaeis guineensis Jacq. (dende), Swietenia macrophylla King (mahogany), Sclerobium paniculatum Vogel (taxi branco) and Bixa orellana L. (urucum) within the different plant fraction were determined. The elements Ca, Mg, K, Na, Fe, Al, Zn, Cu, and P were analysed with the inductively coupled argon plasma with optical-emission-spectrometry (ICP-OES) method. Compared to plants of temperate regions, the mineral content is distinctly higher than that for tropical plants, but most values still lie within the range of existing data. Extremely high values were found for aluminium and iron.
