Estimasi Persentase Karbon Organik pada Tanah di Hutan Mangrove Alami, Perancak, Bali

Mangrove is one coastal ecosystems that play a role in taking and storing a number of carbon known as Coastal Blue Carbon. Soil storage (below-ground) in mangrove forests has a potential of 50% to 90% more than the total carbon stock of coastal ecosystem. This study was conducted at 3 plots in Perancak Mangrove Forest, Jembrana, Bali with the aim of estimating the percentage of organic carbon and to find out the percentage of vertical variation of organic carbon in the soil. Sampling time was conducted in June 2015. The data required to calculate the percentage of organic carbon in the soil is the depth of soil samples, depth and sub-sample intervals, and bulk density. The results found that the percentage of organic carbon in the soil in Perancak natural mangrove was 50.235% or 185.968 Mg/ha. Vertically the percentage of organic carbon in soils in Perancak natural mangrove forests was varies. The lowest value of bulk density depth of 0-15 cm was 0.07 g/cm3 plot 1 and the highest was 0.20 g/cm3 in > 100 cm depth plot 3. The lowest value of the percentage of organic in the depth > 100 cm was 47.899% plot 2 and the highest was 51.821% in the depth of 50-100 cm at plot 1. The lowest value of soil C was 17.361 Mg/ha in the depth of 0-15 cm and the highest was 62.962 Mg/ha in the depth of 50-100 cm plot 1.
