Resumo: | It was evaluated the effect of different residue management systems in the plant nutrition status, nutrient contents in the litter and litter biomass yield, on Eucalyptus grandis plantation. Samples were taken on four residue management systems: (i) removal of all residues from previous harvesting and NPK fertilization; (ii) maintenance of all residues on soil surface and NPK fertilization; (iii) removal all at bark and commercial-size crop stems over 3 cm diameter and NPK fertilization; (iv) removal of all residues from previous harvesting, NPK fertilization and addition of industrial waste (15 t.ha-1 of pulp and paper sludge, C:N ratio 25:1 and 4 t.ha-1 of wood ash, C:N ratio 30:1). Results showed that the maintenance of the forest residues on site improved the nutritional status of trees and increased productivity. Addition of industrial waste allowed expressive increase of Eucalyptus sp growth. Possible excesses of Ca from the industrial waste used should be corrected, to avoid nutritional unbalance in the trees; independent of the treatment used, the amounts of K added to the soil are not enough to maintain appropriate tree nutritional status. Greater amounts of K should be added to correct soil nutritional deficiencies on this element. |

Neste trabalho foi avaliado o efeito de diferentes manejos de resíduos florestais no estado nutricionaldas árvores, no conteúdo de nutrientes na serapilheira e a biomassa de serapilheira produzida pelo Eucalyptusgrandis. Foram avaliados quatro sistemas diferentes de manejo de resíduo: (i) remoção de todo resíduo do sítioproveniente da colheita florestal e adubação NPK; (ii) manutenção no sítio de todos os resíduos da colheitaflorestal e adubação NPK; (iii) remoção do sítio de todo o resíduo da colheita com diâmetro superior a 3 cm eadubação NPK; (iv) remoção de todos os resíduos da colheita, adubação NPK e adição de 15 t.ha-1 de resíduocelulósico + 4 t.ha-1 de cinza de madeira (relação C:N igual a 25:1 e 30:1, respectivamente). Os resultados mostraramque a manutenção no sítio do resíduo da colheita florestal melhora o estado nutricional das árvores e aumenta aprodutividade; a adição de resíduo celulósico permitiu aumento expressivo de produtividade; as altasconcentrações de Ca no resíduo celulósico devem ser corrigidas com aplicações de K e Mg para evitar desequilíbrionutricional nas árvores; para todos os tratamentos, as quantidades de K acrescentadas não foram suficientespara manter as árvores adequadamente nutridas com este nutriente.Embrapa Florestas2010-03-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/60Pesquisa Florestal Brasileira; n. 56 (2008): jan./jun.; 31Pesquisa Florestal Brasileira; No. 56 (2008): jan./jun.; 311983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/60/60Bellote, Antonio Francisco JuradoDedecek, Renato AntonioSilva, Helton Damin dainfo:eu-repo/semantics/openAccess2017-04-28T14:07:52Zoai:pfb.cnpf.embrapa.br/pfb:article/60Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2017-04-28T14:07:52Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
