Summary
This global meta-analysis synthesises peer-reviewed evidence on the impact of soil amendments on soil acidity and crop yields in acidic soils. The authors aggregated results across multiple studies and geographic regions to characterise the efficacy of different amendment strategies, as suggested by the systematic scope and multi-author international collaboration. The findings are likely to inform soil management practice and policy in regions with acidic soil constraints.
UK applicability
The United Kingdom has extensive areas of naturally acidic soils, particularly in upland regions and on sandy parent materials, making amendment strategies relevant to UK arable and grassland management. However, applicability depends on whether the meta-analysis included temperate maritime climates and whether recommendations align with UK soil types and farming economics.
Key measures
Soil acidity (pH); crop yield; amendment type and application rate; effect sizes across studies
Outcomes reported
The study synthesised global evidence on how various soil amendments affect soil pH and crop yields in acidic soils. It quantified the effectiveness of different amendment types across diverse geographic and agronomic contexts.
