Resumo: | Large quantities of organic wastes are produced mainly in big cities, annually. There is urgent demand for safe and possible economic practices for its use on forest plantations. This study evaluated the effects of the application of urban waste and mineral fertilizers on Eucalyptus grandis W. Hill ex Maiden plantation growing on Neossolo Quartzarênico, analyzing nutrient contents in the litter and in the above ground biomass of trees at 86 months old. The results showed that those plots that received organic wastes presented biomass increments of 36.9 % and largest contents of N, P, K and Ca, 86 months after the establishment. After harvesting, largest nutrient pools remained on those same plots (18 % to 49 %), contributing significantly to maintain forest productivity. This study emphasized also the importance of keeping tree bark on site. Debarking tree on field accounted to an average of about 32 % of total nutrients present in the above ground biomass of the trees. Large quantity of nutrients in the canopy tree and litter highlights the importance to conserve this organic matter to contribute to the sustainability of the forest productivity.
