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.

Understanding the movement and alteration of carbon nitrogen elements in soil is crucial for addressing ecological restoration coal mining subsidence areas. However, migration process mechanisms these during natural remain unclear. This study analysed fluctuating variations formation TC TN content profiles at different times Initially, both contents decreased followed by an increase process. Soil compaction effects, variation C/N ratio, enzyme activity were considered as predominant factors controlling element cycles collapsed profiles. will provide valuable insights into understanding behind recovery while establishing a scientific basis

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

Plant Cell & Environment, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 17, 2024

The application of microbial inoculants holds promise for the sustainable restoration abandoned mine sites by affecting soil nutrients and communities. However, responses plant communities to in remain largely unknown. To bridge this knowledge gap, we conducted a 4-year field experiment at an carbonate site assess impacts on soil-plant microbiome. Our findings revealed that significantly changed roots, fine root bacterial fungal Further, no significant correlations were observed between nutrient content (Z-score) alpha diversity. positive correlation was found relative abundance keystone ecological cluster (Module #1) content. also increased complexity, albeit decreased stability microbiome networks, alongside reduction stochastic assembly. Conversely, they complexity but accompanied increase Notably, number specifically enriched functional traits roots nodules under inoculant treatments surpassed control.
