Summary
This systematic review examined the influence of chemical fertiliser and manure-based inputs on soil health properties, an area comparatively understudied relative to crop performance and environmental outcomes. The authors conclude that chemical fertilisers can enhance soil organic matter and health when application rates do not exceed plant utilisation capacity, whilst manure inputs contribute to soil organic carbon; however, inconsistent application bases (nutrient versus carbon) complicate direct product comparisons. The review identifies beneficial effects of nutrient inputs on soil health but highlights the need for more focused research into mechanisms and optimal practices.
Regional applicability
The review's global scope suggests findings are potentially applicable to United Kingdom farming systems; however, applicability depends on whether the reviewed studies included UK-representative soil types, climate conditions, and crop systems. UK practitioners should note that conclusions regarding optimal fertiliser application rates and manure incorporation practices may require contextualisation to UK soil and weather conditions.
Key measures
Soil organic matter, soil organic carbon, soil health metrics (not further specified in abstract), nutrient use efficiency
Outcomes reported
This review synthesised literature on how chemical fertiliser and manure-based nutrient inputs influence soil health properties, including soil organic matter and soil carbon. The authors identified research gaps and conclusions regarding optimal application rates and differential effects of input types on soil health metrics.
