This study investigates the status of soil organic matter in mangrove areas dominated by Avicennia marina and Excoecaria agallocha in Tambak Oso Village, Sidoarjo Regency, Indonesia using purposive random sampling across different vegetation densities (low, medium, high), the research analyzed soil pH, redox potential, organic carbon, and total nitrogen. Results indicate that Avicennia marina areas had higher soil organic carbon due to faster litter decomposition and humification, attributed to lower lignin content. In contrast, Excoecaria agallocha soils contained higher total nitrogen, especially under medium vegetation density, likely due to slower litter decomposition providing sustained nitrogen release. Furthermore, vegetation density influenced soil pH and redox potential, where higher density increased pH (towards neutral) and decreased redox potential, promoting anaerobic conditions favorable for carbon stabilization. The dominant soil texture was sandy clay loam, aiding moisture and organic matter retention. These findings highlight the differential contributions of mangrove species and vegetation density to soil nutrient dynamics and have implications for sustainable mangrove restoration and management strategies.
