| Abstract: | Effects of biochar on soil water-stable aggregates and total carbon were investigated with three biochar treatments in Granitic Laterite. Eighteen months later, results showed that, compared with the control, the biochar treatments of 0.5% and 1.0% significantly increased geometric mean diameter (GMD) of water-stable aggregates by 15.64% and 10.80%. Both treatments increased the contents of >5 mm water-stable aggregates by 98.75% and 88.37%, respectively. The biochar treatment of 1.0% increased the total carbon of 3~5 mm, 2~3 mm and 0.5~1 mm water-stable aggregates by 32.24%, 39.31% and 306.36%, respectively, and increased the distribution proportion of total carbon in >5 mm water-stable aggregates by 90.44% compared with the control. Therefore, biochar was beneficial for latosol to improve soil structure and increase soil total carbon. |
