This study aims to analyze Nitrogen and Carbon contents in the soil of a mangrove forest in Tongke-Tongke, East Sinjai. The stations were determined by purposive sampling based on the age of mangroves. As a comparison, one station was selected from the outside of mangrove areas (non-vegetation station). There were six stations: Non-vegetation, 1-years-old, 5-years-old, 10-years-old, 27-years-old, and 30-years-old stations. Each stations consist of two substations. Purposive sampling also employed to decide the soil and sediment sample from the mangrove forest. The sample were collected to find out textures and content of Nitrogen and Carbon. 200g sediments (1m x 1m) were taken from each stations used a spade and put them in the labelled plastics. The sample analyzed in laboratory. The result showes that the value of organic Nitrogen is around 14.40 ton ha-1 th-1 to 28.80 ton ha-1 yr-1. Organic carbon content value ranged from 30.36 ton ha-1 to 31.14 ton ha-1. © Published under licence by IOP Publishing Ltd.
