The results showed that AGC stocks were significantly lower than SOC, normally ranging from to tons ha-1 . Using the Walkley-Black method, the total SOC was estimated at the range of to tons ha-1 (with an average of ± tons ha-1 ), which indicated a strong relationship between tree density and SOC. In addition, using the IDW interpolation method, this study estimated that the total CO2 absorbed by mangrove forests was 1,631,834 tons in Bang La and Dai Hop. |
