“…However, although the country has been promoting soil restoration in open-pit mines in arid and semi-arid areas, there are still such phenomena as “high cost” and “reliance on artificial irrigation” [ 8 ]. The cause of formation is that under dry climate conditions, the topsoil used for mulching features a large particle size and a lack of nutrients, so there is no suitable soil environment for microorganisms to survive, which in turn leads to non-decomposition of litter, discontinuous ecological processes, low soil function, and difficulty in vegetation survival and propagation [ 9 , 10 ]. Therefore, a topsoil remediation material that can neutralize salinity and improve soil quality is urgently needed to provide a place and nutrients for microbial activities and build a good soil environment for the normal development of native plants.…”

Open-pit mining causes soil damage and affects the health of the ecosystem. In the arid grassland mining areas, the soil is severely sanded, water-starved, and saline, thus making it difficult for plants and microorganisms to survive. Water-jet loom sludge can be used to improve the quality as it contains a lot of clay and is rich in organic matter, which provides a material basis for microorganism activity. To explore the effects of microbial agent-modified water-jet loom sludge on the restoration of degraded soil in grassland mining areas, four pot trials were set up, i.e., for untreated soil, the application of a microbial agent alone, the application of water-jet loom sludge alone, and the combined application of water-jet loom sludge and the microbial agent. The results show that (1) microbial agent-modified sludge can improve soil water-holding capacity and aggregate stability; (2) the nutrient content of the restored soil fraction increased significantly, and the pH of the original saline soil decreased from 9.06 to 7.84; (3) this method significantly increased plant biomass and microbial biomass carbon and enhanced the abundance and diversity of fungi and bacteria. The three treatments had different results in different soil properties, and the effect of the combined water-jet loom sludge and microbial agent treatment on soil remediation was significantly better than the individual application of either.
