Abstract: RESUMOEste trabalho, realizado em um povoamento de Pinus taeda de 27 anos de idade no município de Cambará do Sul (RS) teve como objetivos: estimar a produção de biomassa, o estoque de nutrientes e avaliar o impacto nutricional de diferentes intensidades de remoção de biomassa com a colheita florestal. A biomassa foi estimada por meio do ajuste (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 madei… Show more

“…Although there is a greater removal of the nutrients from the stands with the increase of the biomass harvest intensity, in practice, the absolute nutrient depletion does not occur. When analyzing this behavior, we observe a transition from a level of productivity in one cycle, to a lower level of productivity in the next cycle, and so on (Schumacher et al, 2013).…”

“…The same order of distribution was found in four-year-old Eucalyptus spp. in Vera Cruz, RS, Brazil (Schumacher et al, 2011); in 18-month-old E. urograndis in Piratini, RS, Brazil (Viera et al, 2012); in the biomass in a clone of E. urophylla × E. grandis, at 5.5 years of age, in the southeastern region of Brazil (Ribeiro et al, 2015); and in the biomass of Eucalyptus spp. in Kenya (Kuyah et al, 2013).…”

“…Comparing the same components, the relative biomass distribution was the same as that found by Guimarães et al (2015) in a four-year-old stand of E. dunnii in the city of Alegrete, RS, Brazil. According to Schumacher et al (2011), the factors that affect the percentage distribution of the biomass in the different components of the trees are species, age, soil fertility and planting density. Therefore, since the genotypes were of the same age, and were planted at the same planting density in the same soil type, the species was the predominant factor that affected biomass distribution.…”

“…In spite of the fact that several studies have been carried out on biomass and nutrient exports in homogenous stands of Pinus (VIERA et al, 2011;SIXEL et al, 2015;CORRÊA;BELLOTE, 2011;SCHUMACHER et al, 2013;LIMA et al, 2016), no records have been found in up-to-date literature on studies of mixed plantings of species of the same genus. Therefore, the objective of this study was to quantify the biomass and nutrients of the aerial part of trees and to evaluate the effect of harvest residues management on the removal of nutrients from pure and mixed plantations of Pinus sp..…”
