Biomassa e estoque de nutrientes em plantios clonais de Eucalyptus saligna Smith. em diferentes idades

Abstract: ResumoO presente trabalho teve por objetivo, quantificar a biomassa e o estoque de nutrientes de um clone de Eucalyptus saligna em quatro idades no município de Telêmaco Borba -PR. O trabalho foi realizado em povoamentos com idades de 1,1; 3,6; 5,5 e 6,7 anos. As árvores foram separadas nos componentes: folhas, galhos, casca e madeira do tronco, coletando-se uma amostra representativa de cada fração. A biomassa total encontrada foi de 37,35; 190,03; 227,12 e 249,49 Mg ha -1 nas idades de 1,1; 3,6; 5,5 e 6,7 a… Show more

“…In average terms, for the relative partition of the total biomass, the wood represents 66% of the tree biomass, and when considering only the aboveground biomass this condition rises to 76%. The distribution of the biomass between the respective components presented the same tendency being wood > root > branch > bark > leaf, which corresponds to the one verified by several authors [7,16,17,18]. .…”

“…The amount of nutrients in the bark and canopy (branches, leaves and tree tops), expresses the importance of the presence of these components in the post-harvest site. In the present study, it was observed that the removal of only wood from the trunk reduces the export of nutrients from the system, mainly in areas of low fertility, contributing to the maintenance and productive capacity of the soil [7,18,27].…”

“…point out to soil type and nutrient availability as the main factors affecting yield potential on commercial forest stands Salvador et al (2016). obtained 289,49 Mg ha -1 of total above-soil biomass, at a 6,7-years-old Eucalyptus saligna stand, considerably higher than the value found at the SPA.…”
