Summary
This global meta-analysis of 51 peer-reviewed studies systematically quantified the comparative effectiveness of microbial consortium inoculation versus single-species inoculation for enhancing plant growth and soil remediation. Consortium inoculations substantially outperformed single-species treatments, with synergistic effects between commonly used genera (Bacillus and Pseudomonas) contributing to this advantage. Although consortium efficacy was reduced in field settings relative to controlled greenhouse conditions, consortia maintained a more consistent advantage across varying environmental conditions.
UK applicability
The findings support adoption of microbial consortium inoculation as a soil amendment strategy in UK farming and contaminated land remediation contexts. The recommendation to optimise soil pH (6–7) and increase organic matter and available nitrogen and phosphorus aligns with UK soil management best practice, though field-level efficacy may require localised validation under UK pedoclimatic conditions.
Key measures
Percentage increase in plant growth and pollution remediation relative to non-inoculated controls; efficacy under greenhouse versus field conditions; soil pH, organic matter, available nitrogen and phosphorus content
Outcomes reported
The study compared the effects of single-species versus microbial consortium inoculations on plant growth (biofertilization) and pollution remediation (bioremediation) across 51 field and greenhouse soil studies. Plant growth increases and pollution remediation efficacy were quantified and compared between treatment types.
