Soil carbon on various land uses of Mangrove, Derris and Nypa ecosystems in Segara Anakan – Central Java

Mangrove is one of the essential ecosystems that absorb carbon most productively and efficiently compared to other ecosystems. Carbon is important to maintain the balance of mangrove ecosystem. However, mangrove carbon content varies depending on the formation of sediment, thickness, and plant composition. The objectives of this study are to assess soil carbon content at various types of mangroves communities and land use in Segara Anakan. Fifty-Eight plots (size of 30 x 10 m2) were selected to determine the carbon storage in the dense mangrove (M1), moderate mangrove (M2), planted mangrove (MT), Derris (D), Nypa (N), Rice fields (S), Shrub (LT), and Terrestrial vegetation (V). Mangrove substrates were taken using an auger in the plots at five ranges of depth. The results showed that the highest carbon and water content wereas found in planted mangroves, followed by dense mangroves. The lowest water content was in paddy fields and terrestrial vegetation, while for carbon content the lowest was found in the shrub. The carbon content of the dense mangrove and planted mangrove were in the range of 4.57 ± 0.85 - 6.07 ± 1.18% and 5.02 ± 0.80 - 7.45 ± 0.61%, respectively.
