Resumo: http://dx.doi.org/10.5902/198050989278This study was conducted in a 27 year Pinus taeda stand in Cambará do Sul, Rio Grande do Sul state and aimed to estimate the biomass production, nutrient stock and to evaluate the nutritional impact in different forest harvesting intensities. Biomass was estimated through regression equation adjustments, with the cut of 15 trees distributed in 5 diametric classes. Nutrients stock was obtained through the product between the average content of nutrients in each biomass component and the number of trees per diametric class per hectare. Pinus taeda above ground biomass was estimated in 266.08 Mg ha-1, being 69.1% of wood, 17.1 of live branches, 6.7% of bark, 3.8% of dead branches and 3.4% of needles. Nutrients stock in biomass (kg ha-1) was estimated in: 511.96 of N, 44.39 of P, 174.27 of K, 310.77 of Ca, 103.80 of Mg, 115.36 of S, 2.94 of B, 0.62 of Cu, 17.34 of Fe, 36.70 of Mn and 4.46 of Zn. Nutrients stock relative distribution in Pinus taeda biomass components showed the following sequence: wood (43.6%), live branches (24.8%), needles (19.0%), bark (8.7%) and dead branches (3.9%). Total above ground biomass harvest, when compared to only wood removal, leads to nutrients export increase that can vary from 58.0% to 127.4%, depending on the chemical element, while biomass removal increases 40.8%.

A biomassa foi estimada por meio do ajuste de equações de regressão, com coleta de 15 árvores distribuídas em 5 classes diamétricas. O estoque de nutrientes foi obtido pelo produto entre o conteúdo médio de nutrientes em cada componente da biomassa e o número de árvores por classe diamétrica por hectare. A biomassa de Pinus taeda, acima do solo, foi estimada em 266,08 Mg ha-1, sendo composta por: 69,1 % de madeira do tronco, 17,1 % de galhos vivos, 6,7 % de casca do tronco, 3,8 % de galhos secos e 3,4 % de acículas. O estoque de nutrientes na biomassa, em kg ha-1, foi estimado em: 511,96 de N; 44,39 de P; 174,27 de K; 310,77 de Ca; 103,80 de Mg; 115,36 de S; 2,94 de B; 0,62 de Cu; 17,34 de Fe; 36,70 de Mn e 4,46 de Zn. A distribuição relativa do estoque total de nutrientes nos componentes da biomassa de Pinus taeda apresentou a seguinte sequência: madeira do tronco (43,6 %), galhos vivos (24,8 %), acículas (19,0 %), casca do tronco (8,7 %) e galhos secos (3,9 %). A colheita de toda biomassa acima do solo, quando comparada com a retirada apenas da madeira do tronco, acarreta uma elevação na exportação de nutrientes que pode variar de 58,0 % a 127,4 %, dependendo do nutriente, enquanto a remoção de biomassa aumentou 40,8 %.Universidade Federal de Santa Maria2013-06-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/927810.5902/198050989278Ciência Florestal; Vol. 23 No. 2 (2013); 321-332Ciência Florestal; v. 23 n. 2 (2013); 321-3321980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/9278/pdfSchumacher, Mauro ValdirWitschoreck, RudiCalil, Francine NevesLopes, Vicente Guilhemeinfo:eu-repo/semantics/openAccess2017-04-17T14:10:43Zoai:ojs.pkp.sfu.ca:article/9278Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-17T14:10:43Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
