“…In this sense, the use of nitrogen fixing bacteria as an important way to make this nutrient available after the establishment of symbiosis with legumes has been intensively studied. Numerous studies have shown that symbiosis increases N accumulation for many legumes (Calheiros et al, 2013;Moura et al, 2016).…”

The intense exploitation of coal deposits in Southern Brazil has caused severe degradation problems in extensive areas. In order to recover such areas, the use of revegetation with species adapted to disturbed environments and with the capacity to establish mutual relationships with microorganisms have been of great value. The objective of this study is to characterize plant-root symbioses in two grass-legume (Calopogonium mucunoides with Brachiaria decumbens and Vicia sativa with Brachiaria decumbens) consortia inoculated with soil of the Carboniferous Basin in the state of Santa Catarina. Areas evaluated were at different stages of land reclamation and the influence of those consortia on the occurrence of rhizobia, arbuscular mycorrhizal fungi, and in the community of endophytic bacteria were evaluated. The study was done in two independent experiments in a completely randomized design, with five replications; done under greenhouse condition. There were seven treatments-five inoculated (with soil obtained from areas of 2, 4, 6 and 12 years of recovery, and a reference area) and two control treatments without inoculation (with low and high concentrations of mineral nitrogen). After 50 days of implantation, soil and plant material were collected to characterize root symbioses by nodule counting, nitrogen fixing bacteria isolation, mycorrhizal occurrence (%), and characterization of root endophytic bacterial communities. Only the calopogonium-brachiaria consortium was able to nodulate with rhizobia from the recovering coal mining areas. Arbuscular mycorrhizal fungi (AMF) and endophytic bacteria occur in the vetch-brachiaria and calopogonium-brachiaria consortia regardless of the time of recovery. The microbial communities present in soils with different stages of recovery are more efficient in promoting plant growth in the calopogonium-brachiaria consortium and this behavior may be associated with the calopogonium's ability to associate with autochthonous rhizobia.

“…Use of quick growing N-fixing plant species in revegetation for restoring degraded coal mine soil could be an effective method by enhancing nutrient cycling, reducing soil erosion, and increasing C assimilation in the soil [5]. N is one of the most important nutrients required for plant growth and development [6].…”

This study was conducted to evaluate the effect of fertilization and nitrogen fixing (N-fixing) bacterial inoculation on the vegetative growth of alder (Alnus sibirica) plant species while grown in coal mine soil. The study was conducted in a greenhouse of the Forest Science Department, Chungbuk National University, South Korea, during the period of May 2019 to July 2019. A completely randomized design (CRD) comprising of four treatments, including T0—non-fertilized non-inoculation (control), T1—fertilization, T2—bacterial inoculation and T3—fertilization along with bacterial inoculation with three replications were used in the study. The results of the study showed that maximum growth of all studied parameters of alder were observed in fertilization along with bacterial inoculation treatment (T3) and this treatment had significant effect on the growth of these parameters as compared to control, except root dry weight and shoot/root ratio. Fertilization treatment (T1) showed significant increase of stem height, shoot fresh and dry weight, plant dry weight, canopy spread, number of leaves, branches and nodes per plant, leaf area and leaf area index of alder in coal mine soil, as compared to control. Bacterial inoculation treatment (T2) also had positive effect on the vegetative parameters of plants comparing to control, excluding root length, root dry weight, shoot/root ratio, and canopy spread. Therefore, it can be summarized that fertilizer application and bacterial inoculation to the soil have a significant role in improving the vegetative growth of alder in coal mine soil.

“…However, coal mining leads to the elimination of topsoil and vegetation cover, discarding of mine fire, overburden materials, etc. ; this kind of activities cause adverse effects on the physical, chemical, and biological properties of the environment, threatening biodiversity and natural resources [2]. Along with severe land deterioration, coal mining often had detrimental effect on ecosystems [3].…”

“…The association between legume species and symbiotic N-fixing bacteria can improve the potentiality of legume species for use in revegetation programs. Their association stimulates increased accumulation of N, decreasing the ratio of soil C/N, which helps mineralization and nutrient cycling, in addition to developing soil organic matter, an essential condition for reclamation of degraded soils [2].…”

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.
