“…SOC has also been used as the most dominant attribute in the 0-10 cm depth for assessing soil quality with different land use and management practices and has been classified as an important attribute for monitoring soil quality in agroecosystems (Shukla et al, 2006). Soil organic C was also reported as the most powerful soil attribute by Brejda Bodlák et al (2012) concluded that SOC content is an appropriate tool for evaluating the soil quality in a reclaimed post-mining landscape. The RMSIs obtained using the PCA were presented in Fig.…”

“…The soil organic carbon (SOC) as a 'trigger' of the soil's physical structure, nutrient cycling, and biological functions [14], plays an essential role in the early stages of pedogenisis and ecological restoration in reclaimed mine soils [15,16]. Research has shown that coal mining may lead to a rapid decrease in the SOC content; the decrease in the SOC pool can reach 70-81% [17].…”

Soil organic carbon (SOC) plays an essential role in the early stages of pedogenisis and ecological restoration in reclaimed mine soils. Dynamic changes in the SOC content are essential for assessing the quality of reclaimed mine soils and the effect of ecological restoration. To objectively assess the carbon dynamics of reclaimed soils, we selected the surface (0-20 cm) soil of farmland under agricultural use (soybean-wheat rotation) from a reclamation chronosequence (R4: 4 years of reclamation, R7: 7 years of reclamation, R10: 10 years of reclamation and R13: 13 years of reclamation) in the Dongtan Mining Area, Shandong Province, China. The adjacent normal, unaffected farmland was used as a control (CK). The results showed that the SOC content gradually increased with the reclamation age until it reached 7.98 g·kg −1 for R13, which accounted for 76% of that of the CK. However, the total carbon contents of the reclaimed soils did not significantly differ from and even appeared higher than that of the CK. This is mainly because the inorganic carbon contents of the reclaimed soils ranged from 2.98 to 12.61 g·kg −1 , all of which were significantly higher than the 0.87 g·kg −1 obtained for the CK. The microbial biomass carbon (MBC) content and the microbial quotient significantly increased with the reclamation age of the soil, and both parameters were markedly higher for R13 than for the CK. The dissolved organic carbon (DOC) content and its ratio to the SOC were significantly higher for R4-R13 than for the CK and DOC/SOC gradually decreased with the reclamation age. Both the reclamation age and the temperature had positive effects on the soil basal respiration (SBR). The SBR rate constantly increased with the reclamation age and was markedly higher at 25 • C than at 15 • C. The temperature sensitivity (Q 10 ) of the SBR showed a clearly decreasing trend for the reclamation chronosequence, but its value remained higher for R13 than for the CK (2.37). The metabolic quotient constantly decreased with the reclamation age, which suggests that the survival pressure imposed on soil microbes by the soil environment gradually decreased. These results indicate that it takes a long time for organic carbon to accumulate in reclaimed mine soil and that rational agricultural use contributes to sustained improvement of the quality of reclaimed soil.

“…This is because SOM influences most soil functions, and it is strongly correlated to the overall soil quality and its capacity to sustain plant biomass production (Lal, ). Ideally, the use of mineral fertilizers and/or manures also can help to improve soil fertility and the reestablishment of the vegetation (Bodlák et al, ; Mukhopadhyay, Maiti, & Masto, ). The efficiency of fertilization can be favored by using fast‐growing intercrops, which roots can help to reduce erosion rates and further strengthen C inputs to the soil (Li, ; Pérez‐Fernández, Calvo‐Magro, & Valentine, ).…”

Mining activities cause severe impacts to soil, the restoration of which requires specific management, and proper evaluation and monitoring. In this research, our objectives were to study recovery strategies and integrate indicators for monitoring the reclamation of an agricultural soil after bauxite mining. Distinct fertilizations (nonfertilized control [CT], poultry litter [PL], chemical fertilization [CF], and PL + CF combined) and intercrops (bare soil with no intercrops [NI], grass [G], legume [L], and G + L combined) treatments were used as recovery strategies to restore soil capacity to sustain a coffee plantation. We selected 27 quality indicators to compare the premining condition, postmining (reconfigured topsoil), and 19 months after the application of fertilization/intercrops treatments. We used univariate statistics to select soil quality indicators and multivariate analyses to group the selected indicators into organic, chemical, physical, and microbiological properties. From each group, one representative attribute was selected, and its averaged weight was summarized into a soil quality index (SQI). In postmining, the estimated SQI was approximately 65% lower than in premining. The SQI recalculated 19 months after the application of fertilization (PL or PL + CF) and intercrops (G, L, or G + L) was 23% higher than in postmining and showed strong correlation with coffee bean yield (at 27 months). Coffee bean yield was highest in plots with L or G + L receiving PL or PL + CF. We conclude that organic amendments and intercrops are suitable approaches to recover soil following bauxite mining, and soil indicators can be integrated to properly monitor the land reclamation progress.
