AB  - It is urgent to restore the ecological function in open-pit mining areas on 
      grassland in Eastern China. The open-pit mines have abundant of mining associated 
      clay, which is desirable for using as a soil source for ecological restoration. 
      The mining associated clay in Hulunbuir district, Inner Mongolia was selected and 
      mixed with a sandy soil at a ratio of 1:1 (S_C soil). Also, effects of arbuscular 
      mycorrhizal fungi (AMF) inoculation on soil functions were studied. The 
      aboveground and underground biomass of maize in S_C soil was 1.49 and 2.41 times 
      higher than that of clay soil, respectively. In the topsoil and S_C soil, the 
      growth hormone (IAA) and cytokinin (CTK) levels of maize were higher than that of 
      clay, while abscission acid (ABA) levels were lower. The inoculation with AMF 
      could significantly improve the biomass of maize and enhance the stress 
      resistance of plants. Through structural equation model (SEM) analyses, it was 
      found that the soil type and AMF inoculation had the most direct impact on maize 
      growth and biomass content. These finds extend our knowledge regarding a low-cost 
      method for physical and biological improvement of mining associated clay, and to 
      provide theoretical support for large-scale application in the future.
