Summary
This 2025 meta-analysis synthesises quantitative evidence on the regulation of soil microbial biomass phosphorus across agroecosystems, examining biotic, abiotic and management controls on this critical component of soil nutrient cycling. The authors identify modifiable agricultural practices—tillage, fertilisation regimes, crop rotation and organic matter inputs—as potential levers to enhance MBP status and phosphorus bioavailability. The findings suggest evidence-based farm management strategies to support soil health, though the magnitude and consistency of practice effects across contrasting agroecosystems warrant site-specific validation.
UK applicability
The findings on tillage, organic matter management and crop rotation are directly relevant to UK farming policy and practice, particularly as soil health and nutrient cycling have become central to agricultural strategies. However, the global scope of the meta-analysis means UK-specific soil types, climates and management intensities should be considered when applying the results to particular regions or farm types.
Key measures
Soil microbial biomass phosphorus (MBP) concentration; biotic, abiotic and management factors affecting MBP; effect sizes of agricultural practices on MBP
Outcomes reported
The meta-analysis synthesised quantitative evidence on factors controlling soil microbial biomass phosphorus (MBP) across diverse agroecosystems, and assessed the effects of modifiable agricultural practices on MBP status. The study examined how tillage, fertilisation regimes, crop rotation and organic matter inputs influence MBP and phosphorus bioavailability.
