Carbonized biomass could be used as a mechanism for long-term storage of C in soils. However, experimental results are variable. Objective of this study was carried out to evaluate the effect of carbonized biomass made from soybean residue on soil organic carbon and seed yield during soybean cultivation. The carbonized biomass was made by field scale mobile pyrolyzer. Pyrolyzer was performed in a reactor operated at 400~500°C for 2 hours using soybean residue. The treatments consisted of four levels as the control without input and three levels of carbonized biomass inputs as 357 kg ha<SUP>-1</SUP>, C-1 ; 714 kg ha<SUP>-1</SUP>, C-2 ; 1,428 kg ha<SUP>-1</SUP>, C-3. It was appeared that seed yield of soybean was 2,847 kg ha<SUP>-1</SUP> for control, 2,897 kg ha<SUP>-1</SUP> for C-1, 2,946 kg ha<SUP>-1</SUP> for C-2 and 3,211 kg ha<SUP>-1</SUP> for C-3 at the end of experiment. It was shown that the contents of SOC were 5.21 g kg<SUP>-1</SUP> for C-1, 5.93 g kg<SUP>-1</SUP> for C-2, 7.00 g kg<SUP>-1</SUP> for C-3 and 4.73 g kg<SUP>-1</SUP> for the control at the end of experiment. Accumulated SOC contents linearly significantly (P < 0.001) increased with increasing the carbonized biomass input. The slopes (0.00162) of the regression equations suggest that SOC contents from the soil increase by 0.162 g kg<SUP>-1</SUP> with every 100 kg ha<SUP>-1</SUP> increase of carbonized biomass rate. Consequently the carbonized biomass for byproducts such as soybean residue could increase SOC. It might be considered that the experimental results will be applied to soil carbon sequestration for future study. More long-term studies are needed to prove how long does SOC stay in agricultural soils.
