Microbial inoculants modify the functions of soil microbes to optimize plant growth at abandoned mine sites.

Mining activities have caused significant land degradation globally, emphasizing the need for effective restoration. Microbial inoculants offer a promising solution for sustainable remediation by enhancing soil nutrients, enzyme activities, and microbial communities to support plant growth. However, the mechanisms by which inoculants influence soil microbes and their relationship with plant growth require further investigation.

Microbial Inoculants Drive Changes in Soil and Plant Microbiomes and Improve Plant Functions in Abandoned Mine Restoration.

The application of microbial inoculants holds promise for the sustainable restoration of abandoned mine sites by affecting soil nutrients and microbial communities. However, the responses of plant microbial communities to microbial inoculants in mine restoration remain largely unknown. To bridge this knowledge gap, we conducted a 4-year field experiment at an abandoned carbonate mine site to assess the impacts of microbial inoculants on the soil-plant microbiome.
