Amycolatopsis acidiphila sp. nov., a moderately acidophilic species isolated from coal mine soil

Revegetation with fast-growing N-fixing leguminous plants can be an alternate for reclamation of degraded coal mining areas. Selection of appropriate plant species is an important factor in deciding the success in the remediation of mine spoil. Thus, this study was carried out in greenhouse conditions to evaluate the effect of two N-fixing leguminous plant seedlings, soybean (Glycine max) and shrub lespedeza (Lespedeza bicolor), on the available N and other soil nutrients (P, K, Ca, and Mg) of the experimental coal mine soil. Four treatments, including T0—non-fertilized non-inoculation (control), T1—fertilization, T2—bacterial inoculation, and T3—combination of fertilization and bacterial inoculation with three replications were applied to both plants. Concentration of NH4+-N and NO3−-N increased significantly in the soil at different treatments for both soybean and shrub lespedeza, as compared to control, but apart from control no significant difference was observed between other treatments of increased NH4+-N for soybean and increased NO3−-N for shrub lespedeza. The highest number of nodules and dry weight of nodule per plant (g) was recorded 5.73 and 1.8, respectively in soybean, and 7.77 and 2.76, respectively, in shrub lespedeza with bacteria-inoculated treatment (T2), whereas fertilized treatment (T1) produced the lowest number of nodule and dry weight of nodule in both plants. Increasing of available P and K was significantly high when NPK fertilizer was applied to the plants but decreased at other treatments. Therefore, it can be concluded that soybean and shrub lespedeza have a significant role in changing soil nutrient status in coal mining soil through fertilizer application and biological N fixation.

Compost Quality

The purpose of this study was to determine the nutrient content of bokashi fertilizers that matched the SNI compost quality standards and the best bokashi and chrysanthemum mixture dosages and the effect of increasing the best chemical status on post-coal mine soil. This research was conducted for two 2 months. The land for this research was taken from post-coal mine land in the Loa Bakung area, Samarinda. The place for conducting research is carried out on Jl. Jakarta Blok BN No 36. Loa Bakung, Samarinda. The method used in this study is descriptive and comparative. This research has 2 stages, namely the first stage of making bokashi kiapu and krinyu mixture and the second stage of the incubation process of post-coal mine soil with a treatment dose that is soil without bokashi, soil with a dose of bokashi 17.5 g polybags, 20 g polybags and 22.5 g polybags, each repeated 3 times. Then analyzed at the Soil Science Laboratory, Mulawarman University Faculty of Agriculture, with parameters pH, C/N ratio, C-organic, N, P, K. Bokashi analysis data based on 2004 SNI Compost Quality Standards and soil analysis data based on soil chemical review status which was developed by the Bogor Soil Research Center in 2009. The results of this study showed that the bokashi mixture of kiapu and krinyu had an effect on increasing soil chemical properties in post-coal mine land, the status of bokashi according to SNI, 22.5% organic C had not matched the quality standard, pH 8.87 not yet according to quality standards, N 1.86% according to quality standards, C/N 12.11 according to quality standards, P 0.98 ppm according to quality standards, and K 2.11 ppm according to quality standards. The best application is at a dose of 22.5 g polybags with a rise at week 4, namely pH 4.94 with acidic status, organic C 2.71% with moderate status, N 0.16% with low status, C/N ratio 16 , 08 with high status, P 31.85 ppm with high status, and K 120.41 ppm with very high status.
