ABSTRACT Global‐scale mining activities have had significant deleterious impacts on local ecosystems and the overall environment, which will necessitate robust restoration efforts. A practical approach includes combining microbial inoculants with technology of external soil spray seeding. This holds potential for sustainable abandoned mine site by enhancing plant growth through modulation nutrients communities. Nonetheless, detailed effects specific aspects community functions their complex interactions remain underexplored, particularly in context To bridge this gap, we performed a four‐year field study at an carbonate location, using metagenomic sequencing to evaluate influence functionality. Our research revealed that introducing greatly enhanced essential parameters notably increased biomass. Additionally, these altered functional gene makeup community, significantly boosting relative abundance processes such as nitrogen fixation, nitrification, denitrification, assimilatory nitrate reduction (ANRA), dissimilatory (DNRA), organic phosphorus mineralization. Conversely, there was decrease carbon degradation, regulation, transport processes. We observed strong correlations between cycles Crucially, affect biomass initially altering properties subsequently coordinating cycles. These findings provide valuable insights into role offer theoretical foundation broader application.
