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.

A aplicação de resíduos orgânicos em plantios florestais é uma alternativa a ser considerada. Este trabalho avaliou os efeitos da aplicação de lixo urbano e da adubação mineral em Eucalyptus grandis W. Hill ex Maiden sobre o acúmulo de nutrientes na serapilheira e na biomassa aérea das árvores aos 86 meses de idade, em Itatinga, SP, em Neossolo Quartzarênico Órtico típico. Verificou-se, nas pcarcelas experimentais com lixo urbano, maiores valores para biomassa arbórea (36,9 % de ganho com relação à testemunha) e maiores conteúdos de N, P, K e Ca no sítio antes do corte das árvores. Após a retirada de madeira (alburno e cerne), observou-se também que com a manutenção das outras partes da árvore nessas parcelas, houve uma maior disponibilização desses nutrientes no sítio, cujos valores foram entre 18 % e 49 % a mais dos conteúdos encontrados para a testemunha, que poderão contribuir para a manutenção da produtividade. Os resultados evidenciaram a importância de se manter a casca das árvores no sítio, pois o descascamento feito no local propiciou, em média, um retorno de 32 % do total de nutrientes acumulados na biomassa aérea. Também, na colheita da madeira, galhos, folhas, ponteiras e serapilheira, devem ser mantidos no campo como um meio de se aumentar o estoque de nutrientes das próximas rotações.Embrapa Florestas2011-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/207Pesquisa Florestal Brasileira; n. 53 (2006): jul./dez.
