Energy capacity of black wattle wood and bark in different spacing plantations PFB - Pesquisa Florestal Brasileira
Eloy, Elder; Silva, Dimas Agostinho da; Caron, Braulio Otomar; Souza, Velci Queiróz de.
The study aimed at the energetic description of wood and bark biomass of Acacia mearnsii De Wild. in two spacing plantations: 2.0 m × 3.0 m × 1.0 m and 1.5 m, during 36 months after the planting. The experiment was conducted in the municipality of Frederico Westphalen, state of Rio Grande do Sul, Brazil. Biomass (BIO), calorific value, basic density, ash content, volatile matter and fixed carbon content and energy density (ED) of wood and bark were determined. The smallest spacing plantation presented the highest production per unit area of BIO and ED of wood and bark.

Organic carbon contents of three tree species in different spacing PFB - Pesquisa Florestal Brasileira
Behling, Alexandre; Sanquetta, Carlos Roberto; Caron, Braulio Otomar; Schimidt, Denise; Elli, Elvis Felipe; Corte, Ana Paula Dalla.
This study aimed to evaluate the content of organic carbon in plant parts (leaves, wood, twigs and bark) of forest species Acacia mearnsii De Wild, Eucalyptus grandis Hill and Mimosa scabrella Benth, under different spacing between trees (2.0 m x 1.0 m, 2.0 m x 1.5 m, 3.0x1.0 m and 3.0 m x 1.5 m), one year after planting. It was also aimed to verify if the conversion factor of 50% can be applied. To determine the organic carbon it was used a carbon analyzer(C-144). The carbon content varied depending on the species, spacing and the part of the plant component used. It was observed that the factors: species, spacing, and parts of the plant are not independent. So, the carbon content measurements should be determined for each species and for each biomass...
