Abstract

The present study was conducted in Tebing Tinggi Village, Pulau Punjung Sub-district, Dharmasraya District was motivated by a desire to exploit land resources, especially open access land that was formerly a gold mine by cultivating oil palm plants. The objectives of this study were to determine the characteristics of soil chemical properties, the soil fertility level, and the level of mercury (Hg) contamination in former gold mining land by compared with the soil chemical fertility of oil palm plantations. The research method was a survey by purposive sampling. The Soil sampling for analysis of soil chemical properties was carried out by drilling of 0-40 cm deep with 12 sample points divided into 4 locations, where 3 locations in the former gold mine area that were grouped into three segments, namely segments 1, 2 and 3 and one location was in oil palm land. The parameters of soil chemical properties observed were pH, Al-dd, C-organic, C / N Ratio, N, P, K and Hg (Mercury). The results of this research, shows that the characteristics of soil chemical properties in the former gold mining area have decreased the level of soil fertility, characterized by the very low pH value and C-organic content, ​​so that the nutrients contained in the land are very limited when compared to the soil fertility in oil palm land. This is indicated by the fact that the oil palm land has a high C-organic content and a moderate level of N-total content. The utilization of the land resources of the former gold mine, it is necessary to do land improvementsin terms of soil physically, chemically and biologically.

Abstract

Land damage caused by gold mining activities is mainly due to soil contamination by Mercury (Hg). Ex-gold mines are soils that have poor chemical, biological, and physical properties, resulting in a very low level of soil fertility. The objective of this study was to determine the effect of rubber leaf litter compost and biochar of oil palm empty fruit bunches to obtain the best dose recommendation in improving the ex-gold mining soil on the growth of rubber seedlings (Hevea brasiliensis Muell. Arg.). This study was designed by a completely randomized design consisted of 7 treatments and repeated 3 times. The treatments were rubber leaf litter compost at a dose of 10 tons/ha and 20 tons/ha, biochar of oil palm empty fruit bunches at a dose of 10 tons/ha and 20 tons/ha, combination of rubber leaf litter compost and biochar of oil palm empty fruit bunches at a dose of 10 tons/ha and 20 tons/ha, respectively. The results showed that the combination treatment of rubber leaf litter compost and biochar of oil palm empty fruit bunches at a dose of 20 tons/ha resulted in a soil pH value of 4,85, Al-dd 0,42 cmol/kg, C-organik 0,92%, N-total 0,053%, C/N 11,25, P-available 122,69 ppm, K-dd 0,40 cmol/kg, and reducing soil mercury by 0,01 ppm. The growth of shoot height and leaves number of rubber seedlings was obtained by the application of biochar of oil palm empty fruit bunches at a best dose of 20 tons/ha. In addition, the treatment of rubber leaf litter compost at a dose of 20 tons/ha was able to increase the leaf width of rubber seedlings (h. brasiliensis Muell. Arg.).
