Impact of root exudates on soil reconstruction and bacterial community resumption in open-pit coal mines
Open-pit coal mine reconstructed ecosystems are ecologically fragile. Retained early stage topsoil is usually not enough to maintain plant growth. For this purpose, we used root exudates to fertilize the reconstructed soil and improve the functioning of the soil microorganism ecology. The roots’ exudates increased the concentration of organic matter and total nitrogen by 16–39%. Within a certain c
