“…In the evidence of this, several studies either from mined or un-mined areas showed that the amount of exchangeable cations in the soil can be positively influenced by the tree species composition (Van Breeman et al, 1997; Finzi et al, 1998a;Mohr et al, 2005) or parent materials of the problem sites (Vimmerstedt et al, 1989;Wali 1999). Moreover, this has mainly been attributed to differences in the pH values (Finzi et al, 1998a), leaf chemistry (Filcheva et al, 2000) and decomposability of the plant materials (Mohr et al, 2005). In our study, however, pH was consistent in all plantations with respect to spoil depth even in UPD site; therefore, attribution by pH might be same.…”

Present study was conducted to investigate spoil characteristics under 5-yr old high-density plantations of three native trees (Albizia lebbeck A. procera and Tectona grandis) and one fast growing woody grass (Dendrocalamus strictus) species on coal mine spoils and same age unplanted mine spoil dump at the same area. We examined physical characters such as soil bulk density, water holding capacity, soil texture (sand, clay and silt) and chemical characters such as pH, total nutrients (C, N and P) and exchangeable cations (Ca, Mg, K and Na) in chronosequence of spoil depth (0-50 cm) at 10 cm interval under planted stand of each selected species and unplanted dump. A significant effect of plantations on physico-chemical characteristics (except soil bulk density) of mine spoils was found. Among species, A. lebbeck exhibited substantial improvement in mine spoil soils followed by D. strictus, A. procera and T. grandis plantation. Although, chemical characteristics especially total concentrations of soil C, N and P and their ratios were significantly different due to species and spoil depth, indicating plantations of all species have abilities to improve soil chemical qualities at young stage of establishment. Compared to unplanted dump, plantation of A. lebbeck showed highest concentrations of total nutrients (C, N and P) and exchangeable cations with respect to spoil depth followed by D. strictus, A. procera and T. grandis, which confirms that some species have suitable qualities for the modification of spoil characteristics during rehabilitation process.

“…The restoration of lands affected by surface coal mining is an increasingly important concern in many countries (e.g. Filcheva et al 2000;Bell 2001;Shrestha and Lal 2006;Pietrzykowski and Krzaklewski 2007). Large portions of these areas are reclaimed for forestry (Smith 2002).…”

Abstract:It is not clear to what extent trees growing on anthropogenic sites change their growth and biomass allocation to different organs. We assessed the aboveground biomass in a chronosequence of six Scots pine monocultures (between 6 and 20 years old) to examine how precisely the site-specific or control allometric equations may reflect the value of biomass accumulation and allocation in stands growing in harsh site conditions on the overlayer spoil heap made as a result of opencast brown coal mining. The site is characterized by poor edaphic and water conditions and nutrient deficiency. The control equations were developed from Scots pine stands growing on post-agricultural lands in the close vicinity of the spoil heap. We found that equation type significantly influenced results of predicted biomass accumulation for all biomass components studied (although results were only marginally significant for total aboveground biomass, P=0.08). Total aboveground biomass in younger stands (6-9 years old) estimated using site-specific equations was >40% higher and for older stands (17-20 years old) from 7 to 27% lower than estimated using equations developed for the control sites. Our study revealed that under harsh environmental conditions in spoil heaps, biomass of young Scots pine stands significantly differ from values calculated based on control equations developed for more fertile soils with better water conditions in the same region. The control biomass equations may not be suitable to estimate biomass accumulation in stands growing on infertile habitats with poor water conditions, if the control equations are developed for nearby stands but growing under better site conditions.

“…Given that members of the Bacillus genus exhibit PGP activities [24,32], we used 13k/19k to co-inoculate the seeded substrates. The co-inoculum caused an increase in the total number of microorganisms in 100% OS from 2.45x10 6 to 3.12x10 6 CFU/g (oat) and from 2.02x10 6 to 3.12x10 6 CFU/g (lettuce) (Fig. 3).…”
