“…The results of Pearson correlation analysis indicated that there were significant relationships among the SOC, SOCD, TN, and TND in the top 20 cm soils in both periods ( p < 0.01; Table 2 ). Consistent changes in the SOC and TN levels in many different wetlands have been reported by the majority of researchers 4 9 11 . Significant positive correlations between pH values and soil C and N indicated that higher pH ranges (i.e., medium alkaline) prohibited soil C and N decomposition through influencing microbial activity 48 .…”

“…Therefore, the accurate estimations of soil organic carbon (SOC) and total nitrogen (TN) are essential for the detection of potential carbon and nitrogen sequestrations and emissions in wetlands 8 . Some researchers have focused on SOC and TN contents and stocks in different ecosystems including wetlands 9 10 11 . It is estimated that 20–30% of the earth’s soil carbon pool of 2,500 Pg is stored in wetlands because wetlands provide an optimum natural environment for the sequestration and long-term storage of carbon 12 .…”

Changes in the sources and sinks of soil organic carbon (SOC) and total nitrogen (TN) in wetland soils as indicators of soil quality and climate change have received attention worldwide. Soil samples were collected in 2007 and 2012 in the coastal wetlands of the Yellow River Delta and the SOC and TN were determined to investigate a five-year change in their content and stock in these wetlands as affected by flow-sediment regulation. Our results revealed that the soils in 2007 exhibited greater electrical conductivities, SOC content and density, and ammonium nitrogen (NH4+-N) levels in the top 10 cm soils (p < 0.05) compared with the soils in 2012. In general, the SOC and TN contents decreased with increasing soil depth. However, the highest ratios of soil organic carbon and total nitrogen (molar C/N ratios) were observed in the 30–40 cm soil layer. A significant SOC loss occurred (p < 0.05) in top 10 cm soils, but only a small change in SOC in the top 50 cm soils. Comparatively, TN levels did not show significant differences in the study period.

“…The belowground C pools of the mangrove forest transects were greater at 315, 428, and 818 Mg/ha for the seaward, interior, and landward zones, respectively [23]. In the study of Eid and Shaltout [59] soil organic carbon was higher in the surface soil where most carbon inputs occur and decreases with depth, this supported by some previous studies such as [60,61,62]. According to Girmay and Singh, [63] variation in SOC content distribution with depth are the result of interaction of complex processes such as decomposition, biological cycling, leaching, illuviation, soil erosion, weathering of minerals and atmospheric deposition.…”

Carbon dioxide (CO2) once emitted to the atmosphere, takes centuries for natural removal. Every 4 giga tones of carbon (GtC) emitted to the atmosphere results in a rise of one ppm of CO2 in the atmosphere. Mangroves growing near the coast play an important role in carbon sequestration by acting as sink for carbon, thereby receiving considerable international attention. In India Mangroves occupy 4740 sqkm, about 3 % of the world’s mangrove cover. Sundarbans in India is the largest mangrove site in the world, colonized with many threatened animal species. The paper attempts to highlight the Carbon storage in Mangrove living biomass and sediments particularly of South Asian and Indian regions. Reviews suggest that C storage in mangroves at different climatic regions, sites, stands and different depths of soils store more carbon per unit area. All the reviews suggest that mangroves are a globally significant contributor to the carbon cycle.

Ekosistem mangrove memiliki kemampuan untuk menyerap dan menyimpan karbon. Beberapa penelitian memperlihatkan besarnya kemampuan penyerapan dan penyimpanan karbon oleh ekosistem ini. Namun demikian, kapasitas penyimpanan ini akan menurun karena deforestrasi dan konversi lahan. Tujuan penelitian ini adalah menganalisa dampak alih fungsi lahan mangrove terhadap sifat sedimen serta kemampuannya dalam menyimpan karbon. Penelitian dilakukan di empat lokasi yaitu di Kabupaten Berau - Kalimantan Timur dan Karimunjawa-Jawa Tengah yang mewakili daerah alami serta, Kabupaten Pati - Jawa Tengah dan Kabupaten Indramayu – Jawa Barat yang mewakili mangrove yang pernah mengalami alih fungsi lahan dan telah direhabilitasi. Sedimen diambil minimal sampai pada kedalaman satu meter dengan menggunakan soil auger. Sebanyak empat sampel diambil pada setiap core sediment pada interval kedalaman 0-15, 15-30, 30-50 dan 50-100 cm. Mangrove yang pernah mengalami alih fungsi lahan memiliki nilai bulk density yang lebih tinggi serta konsentrasi CN (%) dan simpanan karbon (MgCha-1) yang lebih rendah dibandingkan dengan lokasi yang alami. Hasil penelitian ini menunjukkan bahwa alih fungsi lahan mangrove menurunkan kemampuan penyimpanan karbon ekosistem dan diperlukan waktu untuk meningkatkan nilai simpanan karbon sedimen pada daerah yang pernah mengalami alih fungsi.
