Resumo: | Plantation forests in Brazil cover 7 million hectares, which represents 1% of the country (68% of Eucalyptus and 25% of Pinus plantations). The aim of this study was to evaluate a Eucalyptus urograndis plantation. High levels of Ca and Mg in the soil suggest that limestone had leached into the soil profile. The soil resistance down to 60 cm depth in the row of planting was lower than the inter-row space, indicating that deep tillage had been effective. Soil resistance, down to 20 cm depth at an inter-row distance of 1 m from the planting row, was higher, likely by the increase in soil compaction during the site preparation. The canopy biomass differed amongst the DBH classes, justifying the use of an allometric equation based on a basal area for assessing the canopy biomass. The observed variation in DBH did not correlate with variation in wood density. The wood density of 0.37 g cm-3 was lower than those reported for 7-year-old plantation. The in situ removal of the bark increased nutrient availability by 8-11%. Harvesting of tree bole in 3-year old plantation didn’t result in a large nutrient export, indicating that proper plantation management can contribute to plantation forest sustainability. |

Estoques elevados de Ca e Mg no solo, sugerem uma lixiviação do calcário. A resistência do solo até os 60 cm de profundidade na linha de plantio foi menor do que na entrelinha, indicando que a subsolagem foi eficiente. Os valores de resistência do solo foram mais altos na entrelinha, distante 1 m da linha de plantio, até os 20 cm de profundidade, provavelmente pelo aumento da compactação na preparação da área. A biomassa da copa das árvores diferiu entre as classes de DAP, justificando o uso de equação para a sua estimativa. A variação observada para área basal não refletiu em diferenças de densidade da madeira. A densidade da madeira de 0,37 g cm-3 foi menor do que a de plantios com 7 anos. A remoção da casca no campo aumentou o suprimento de nutrientes entre 8% e 11%. A colheita da madeira aos 3 anos não resultou numa exportação significativa, indicando que o manejo apropriado dos plantios, pode contribuir para a sustentabilidade florestal.Embrapa Florestas2011-11-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/27310.4336/2011.pfb.31.68.331Pesquisa Florestal Brasileira; v. 31 n. 68 (2011): out./dez., Florestas Energéticas; 331Pesquisa Florestal Brasileira; Vol. 31 No. 68 (2011): out./dez., Florestas Energéticas; 3311983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/273/232Copyright (c) 2011 Guilherme de Castro Andrade, Itamar Antonio Bognola, Antonio Francisco Jurado Bellote, Luziane Franciscon, Maarten Johannes Waterloo, Leendert Adriaan Bruijnzeelhttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessAndrade, Guilherme de CastroBognola, Itamar AntonioBellote, Antonio Francisco JuradoFranciscon, LuzianeWaterloo, Maarten JohannesBruijnzeel, Leendert Adriaan2021-03-19T21:56:12Zoai:pfb.cnpf.embrapa.br/pfb:article/273Revistahttps://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:2021-03-19T21:56:12Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
