“…Several indices have been proposed to assess soil quality, which were mostly microbial in nature and for agricultural soils (Sharma et al, 2005;Masto et al, 2007aMasto et al, , 2008aOzgoz et al, 2013;Sinha et al, 2009;Morugán-Coronado et al, 2013;van Leeuwen et al, 2015). Indexing involves three main aspects: (1) choosing appropriate indicators for a minimum data set, (2) transforming the indicators to scores, and (3) combining the scores into an index (Sinha et al, 2009). Soil quality indices are useful to differentiate between the degraded status of soils (Morugán-Coronado et al, 2013).…”

Abstract. Assessment of soil quality is one of the key parameters for evaluation of environmental contamination in the mining ecosystem. To investigate the effect of coal mining on soil quality, opencast and underground mining sites were selected in the Raniganj coalfield area, India. The physical, chemical, and biological parameters of the soils, and trace metals and PAHs (polycyclic aromatic hydrocarbons) in the soils were evaluated. Soil dehydrogenase (+79 %) and fluorescein (+32 %) activities were significantly higher in underground mine (UGM) soil, whereas peroxidase activity (+57 %) was higher in opencast mine (OCM) soil. Content of As, Be, Co, Cr, Cu, Mn, Ni, and Pb was significantly higher in OCM soil, whereas Cd was higher in UGM. In general, the PAHs contents were higher in UGM soils, probably due to the natural coal burning at these sites. The observed values for the above properties were converted into a unitless score (0-1.00) and the scores were integrated into an environmental soil quality index (ESQI). In the unscreened index (ESQI-1) all the soil parameters were included and the results showed that the quality of the soil was better for UGM (0.539) than the OCM (0.511) soils. Principal component analysis was employed to derive ESQI-2 and accordingly, total PAHs, loss on ignition, bulk density, Be, Co, Cr, Ni, Pb, and microbial quotient (respiration: microbial biomass ratio) were found to be the most critical properties. The ESQI-2 was also higher for soils near UGM (+10.1 %). The observed indicators and the ESQI results revealed that soil quality assessment for these coal mining soils is largely depended on soil PAHs and potentially toxic trace metals. The proposed ESQI may be further refined by incorporating specific parameters related to human exposure risks and exposure pathways.

“…A mine-soil quality index (SQI) has been used for a selection of tree species suitable for reclamation (Sinha et al, 2009;Mukhopadhyay et al, 2013). In a reclaimed coal mine spoil, SQI progressively increased with the age of reclamation.…”

“…If the high factor variables were not correlated with each other, then each was considered important and thus retained. Among wellcorrelated parameters, the parameter with the highest factor loading was chosen for the SQI (Bastida et al 2006;Masto et al 2008;Sinha et al 2009;C. Zhang et al 2011b).…”

“…If the factor loadings of the parameter in the PCA is "+" (meaning "more is better"), −2.5 was used as the slope value; otherwise ("-", meaning "less is better"), 2.5 was used as the b value (Bastida et al 2006;Masto et al 2008;Sinha et al 2009;C. Zhang et al 2011b).…”

“…A soil microbiological degradation index (MDI) based on five parameters (dehydrogenase activity, water-soluble carbohydrates, urease activity, water-soluble C and respiration) was proposed in a semiarid climate (Bastida et al 2006). Sinha et al (2009) determined that tree species with a higher rhizosphere soil microbial index (RSMI) could be used for revegetation in a degraded coal mining ecosystem. Recently, C. Zhang et al (2011a and2011b) introduced this approach into their evaluation of the impact of revegetation types on soil quality on the Loess Plateau, China.…”

Soil erosion has resulted in serious land degradation in Yuanmou dry-hot valley, Yunnan province, China. Vegetation restoration had been widely developed in this hot and arid area. In this work we investigate the quality of rhizosphere soils under four restoration species in the towns of Zuolin (gully bed) and Yuanma (slope area). [pH, soil organic matter, nitrogen (N), phosphorus (P) and potassium (K) contents], and microbial (microbial biomass and microbe quantity) properties and soil enzyme (catalase, protease and urease) activities were determined. Compared to the soils collected from other vegetation types, the soil under Leucaena leucocephala had the highest content of soil organic matter, total N, available N, total P, available P, available K, microbial biomass carbon (C), and the highest microbe quantity and enzyme activities. Five parameters (organic matter, pH, microbial biomass N, total K and protease activity), which had the greatest weight in the principal components analysis, were selected to calculate the soil quality index (SQI). The final SQI values implied that restoring Leucaena leucocephala greatly improved the soil quality, while restoration with Eucalyptus camaldulensis decreased the soil quality of the slope area. Plant recovery with Dodonaea viscosa and Heteropogon contortus on the gully bed affected the population of soil microbial communities but didn't improve the SQI values. It can therefore be seen that types of plants used for recovery in gully-developed regions in dry-hot valleys must be chosen cautiously: Leucaena leucocephala is a good choice for soil revegetation of the slope area, but the revegetation patterns on the gully bed still need further study.
