Abstract

In open mining system, all layers of soil that are above the mining material are peeled so that the mining material can be extracted. As a result, topsoil and subsoil layers containing organic matter are lost. Organic matter is one component of soil which is very important in creating soil fertility. Therefore, research on soil organic matter content at various ages in post-mining coal reclamation. The method used in this research is survey and analysis methods in the laboratory and uses a Randomized Block Design (RBD). Where the treatment in this study is based on field conditions in the form of age of land reclamation denoted by R, which consists of 5 levels of treatment R0 ( 3 months), R1 (3 years), R2 (4 years), R3 (5 years) and R4 (10 years). With soil sampling done intentionally (purposive sampling) at a depth of 0-30 cm and repeated 5 times. Soil sampling is done by composite. Thus, in this study there were 25 main sample points, where the test sample points were taken from 5 composite sample points originating from around the main point. The results showed that the increasing age of land reclamation could quantitatively increase each soil organic matter, soil pH value and soil N-total. Key words : land reclamation, soil organic matter, soil pH and soil N-total.
