Effects of Restoration Duration and Vegetation Type on Rhizosphere Soil Microbial Carbon and Nitrogen Cycling in an Open-Pit Coal Mine Spoil Heap in Western Inner Mongolia
Low-fertility reconstructed soils in spoil heaps cause slow and fluctuating soil carbon (C) and nitrogen (N) accumulation over time; identifying key drivers is vital. We used metagenomics to examine restoration age and vegetation-type effects on rhizosphere nutrients, aggregate structure, core microbiota, and C–N-cycli...
