Title : The Pattern of Soil Properties and Plant Growth in Reclamation Area of Nickel Mining

Abstract :

Reclamation land is the final step of the nickel mining activity that needs the land management and selection of a suitable plant. Reclamation land has soil characteristics to meet the sufficient conditions in adaption and selection of the plant. So that, it is important to establish the pattern of soil properties and plant growth to guarantee the sustainability function of post-mining land reclamation. This research was the field experiment by conducting determination and observation of the plant growth in reclaimed plant blocks. Plants were observed for sengon (Albizia chinensis), acacia (Acacia mangium), monkeypod tree (Albizia saman), and nedun tree (Pericopsis mooniana). Samples data were collected from 10 trees on each block and observed of height and circular of the trunk. Soil composite samples were collected for soil volume weight (SWG) analysis, soil texture, permeability, pH, C-Organic, and P content. The result showed that (1) the soil characteristic changed the pattern of plant growth in the reclamation area by indicating different variation between plants, (2) the soil characteristic was more affected by chemical than physical properties as shown by plant growth, and (3) sengon and monkeypod trees followed the pattern of changed soil characteristic, while acacia and nedun tree did not change. However, of the four plants mentioned, sengon had the best plant performances in the soil physical and chemical properties at the study site, it could grow and adapt well to nickel ex-mining land even with limited organic matter content. With the results that the contribution to future research on the existence of a selected plant with a low dose of organic matter, can be used as the basis for the management of land reclamation of nickel ex-mining.
