Summary
This systematic review examines the mechanistic role of soil microbial activities in nutrient cycling and transformation, with specific focus on implications for soil fertility and crop productivity. The authors synthesise evidence linking microbial processes—including nitrogen fixation, phosphorus solubilisation, and organic matter decomposition—to nutrient availability and subsequent crop performance. The work contributes to understanding how microbial-mediated soil processes underpin agronomic outcomes, informing evidence-based soil management strategies.
UK applicability
Findings are likely applicable to UK temperate farming systems, particularly regarding management of soil microbial communities to enhance nutrient cycling efficiency and reduce synthetic fertiliser dependence. However, geographic specificity of microbial communities and climate-dependent activity rates may limit direct transfer of quantitative estimates.
Key measures
Nutrient transformation rates, soil microbial community composition and activity, soil fertility indices, crop productivity metrics
Outcomes reported
The study synthesised evidence on how microbial communities and their metabolic activities drive nutrient cycling processes (N, P, K transformation) and their downstream effects on soil fertility status and crop yield outcomes. Likely assessed mechanisms linking microbial diversity or function to nutrient availability and plant-available nutrient pools.
