Leaves of several tree species (Astronium urindeuva, Aspidosperma ramiflorum Muell, Tabebuia flavescens Grise, Terminalia catappa and Joannesia princeps Veill) have been analysed for N, R, K, Ca, Mg, Fe, Zn, Cu and Mn. Results indicated that the mean concentration of these elements are within the average; range of nutrients concentration determined, by several authors. Nutrients content have no regular variation among leaves of different ages, except for Terminalia catappa. Astronium urundeuva is considered a calcicolous plant and this caracteristic could be inferred by the nutrient contents of its leaves.No presente trabalho, foram determinados os teores de N, P, K, Ca, Mg, Fe, Zn, Cu e Mn em folhas de diferentes idades nas espécies: Astro...
