The regulatory role of mine soil properties in the growth of revegetation plants in the post-mine landscape of East Kalimantan

The growth of revegetation plants in post-mining areas is determined by the mine soil quality, which strongly depends on physical and chemical properties original soil. Visual observation two ex-coal mining East Kalimantan, i.e. Lati Sambarata sites, showed a clear difference growth. This research aims to study role rate so that it can be used develop sustainable ex-mining land reclamation strategy. plots each were grouped into (0–2), (2–4), (4–6), (6–8), (8–10), (10–12) years since revegetation. In group, sampling was carried out at depth 0–30 cm for analysis properties. Observations also made development plant better site compared those indicated composition stand structure, stem diameter, height. Both sites have similar texture, dominated silt, slightly higher bulk densities site. Hence, not but chemistry played regulatory plants. Here, exchangeable cations Ca2+ Mg2+, whereas Al3+. Linked with high base saturation, pH, organic C, total N, available P2O5 quality more favourable Thus, activities areas, improvement using lime, rock phosphate, compost indispensable increase fertility establish fast
