Soil organic carbon stores in the mangrove forest restoration of ex-ponds in the Salo Palai Village of Kutai Kartanegara

Abstract

Abstract Mangrove forests in the Mahakam Delta have traditionally been used by people for a variety of purposes, including fuel, hut construction, and charcoal production. Such use is still acceptable as long as it does not reach commercial scale. Where mangrove forests have greater potential for carbon absorption when compared to dry land. In this study, several analyses of bulk density, soil carbon (%), total soil organic carbon (g/cm2), total soil organic carbon (tonnes/ha) were analysed from 3 points with 3 depths (0-50.50-100.100- 150). Then an analysis was carried out using the t test to test whether there was a very significant difference or not. The results of this study showed that ponds without rehabilitation had a total bulk density value of 7.16 g/cm2 with a total soil organic carbon store of 0.34 tons/ha. In the former ponds the rehabilitation area has a total bulk density value of 8.64 g/cm2 with a total soil organic carbon store of 1.01 tons/ha. Based on the results of the t test analysis, it shows that t count > t (0.01) so that it can be said that rehabilitated former ponds provide a very significant difference to carbon storage.
