nvestigation, prospects, and economic scenarios for the use of biochar in small...
John, Vinicius; Braga, Ana Rita de Oliveira; Sousa, Heiriane MartinsThis study investigates the production and economic feasibility of biochar for smallholder and family farms in Central Amazonia, with potential implications for other tropical regions. The costs of construction of a prototype mobile kiln and biochar production were evaluated, using small-sized biomass from acai (Euterpe oleracea Mart.) agro-industrial residues as feedstock. The biochar produced was characterise...

Characterization of biochar produced in a mobile handmade kiln from small-sized...
John, Vinicius; Braga, Ana Rita de Oliveira; Danielli, Criscian Kellen Amaro de Oliveira; Sousa, Heiriane Martins; Danielli, Filipe EduardoSoil amended with biochar is considered a significant response to climate change, remediation of degraded soils, and agronomic improvements. An artisanal mobile pyrolysis kiln was developed for small-sized biomass inputs. Approximately 190 kg of biochar was produced in 21 carbonisation processes using acai residues (Euterpe oleracea Mart.) as raw material, as they are among the most abundant agro-industrial res...

Yield modeling in sawing logs of Manilkara spp. (Sapotaceae) in sawmill in the ...
Danielli, Filipe Eduardo; Gimenez, Bruno Oliva; Oliveira, Criscian Kellen Amaro de; Santos, Joaquim dos; Higuchi, NiroThe aim of this study was to estimate the yield of sawing Manilkara spp. logs, to quantify the wood by products generated, to evaluate differences in the yield between the diameter classes and to adjust models to estimate the yield in lumber and to estimate the volume of the hollow part of the logs. Seventy-one logs were sampled and grouped into diameter classes. Log volumes were determined by the Smalian metho...
Volume equations for merchantable timber species of Southern Roraima state
Gimenez, Bruno Oliva; Danielli, Filipe Eduardo; Oliveira, Criscian Kellen Amaro de; Santos, Joaquim dos; Higuchi, NiroEight volume models were tested to fit observed data from merchantable tree species of Southern Roraima; four simple entry models with DBH as independent variable and four double entry models with DBH and merchantable height (Hc) as independent variables. Among those, the best model was compared with the one which uses form factor equal to 0.7. Additionally, the same models were tested with diameter at stump he...
