Summary
This 2023 review examines the gap between laboratory-demonstrated benefits of plant growth-promoting bacteria and their inconsistent performance in field conditions. The authors synthesise evidence on barriers to PGPB efficacy—including soil environmental stress, microbial competition, formulation stability, and farmer adoption challenges—and propose practical mitigation strategies. The paper contributes to understanding how microbial inoculants can be optimised for real-world agricultural deployment.
UK applicability
The findings are likely relevant to UK farming systems seeking to reduce synthetic inputs through biological amendments; however, soil temperature, moisture variability, and clay-heavy soils in many UK regions may present distinct PGPB application challenges requiring region-specific validation.
Key measures
Qualitative assessment of PGPB field application barriers; proposed solutions and best-practice recommendations
Outcomes reported
The study identifies practical constraints limiting the effectiveness of plant growth-promoting bacteria (PGPB) at farm scale and proposes evidence-based strategies to enhance their field performance and adoption.
