Sampling soil is needed to quantified nitrogen-fixing bacteria, phosphate-solvent bacteria, soil’s macro and micro nutrient content, and also soil field capacity. Sampling method are using composites with 9 sampling points. Soil sample was taken diagonally with distance between points 4,5 meters on the sampling squares which has been made before. Sampling Soil on reclamation area 2004 and 2008 was done on convex, concave, and flat surfaces. Sample ring was used to ease the sampling process on 10-20 cm deep, although the soil was included in disturbed soil sample. After composited, the soil sample were wrapped using plastic bag and labeled, and stored on a cold storage. The soil sample immediately sent to the lab for examination and content analysis.
