Leguminous crops as a nature-based strategy to restore the functionality of reclaimed soils in coal mine agroecosystem
Long-term cultivation of leguminous crops as a nature-based strategy (NbS) has potential for restoring the functionality of reclaimed soils in coal mine agroecosystems. However, the impacts of leguminous crop planting on the physicochemical properties and microbial community structure of reclaimed soil remain poorly understood. To address this issue, a decade-long situ leguminous crop experiment was conducted in a coal mine reclamation agricultural area. The results revealed that, compared with the control, the soybean treatment did not significantly alter the soil field water capacity. However, the soil bulk density and the proportions of solid- and liquid-phases were significantly lower, whereas the gas-phase proportion increased significantly (p < 0.05), and significantly decreased the soil three-phase structure distance (p < 0.05). The soil organic matter, total nitrogen, and inorganic nitrogen contents decreased significantly, whereas the total phosphorus, easily oxidized organic carbon, available phosphorus, and available potassium contents increased significantly (p < 0.05). The key bacterial phyla included Proteobacteria, Acidobacteriota, and Actinobacteriota, while the dominant fungal phyla were Ascomycota, Mortierellomycota, and Basidiomycota. The alpha diversity of both bacteria and fungi under GLY treatment was significantly lower than that in the control, with notable differences in β diversity (p < 0.05). Furthermore, bacterial community network complexity was more pronounced than that of fungal, with the soybean treatment group harboring significantly more bacterial key species than fungal species. Soil bulk density, three-phase structure distance, total phosphorus, and total nitrogen are the primary regulators of soil microbial communities. These findings underscore the efficacy of leguminous crop planting as an NbS for enhancing soil physicochemical properties and optimizing microbial community structure of reclaimed soil. In conclusion, this study highlights the critical role of leguminous crops in sustaining multifunctional reclaimed soils in coal mine ecosystems and the use of leguminous crops for soil reclamation as already a long-established practice.
