Summary
This paper argues that sustainable agricultural productivity requires integrated management of crop nutrient demand, soil elemental stoichiometry (C:N:P balance), and microbial-driven nutrient cycling. The authors present a conceptual framework showing how soil microbiomes regulate nutrient availability and recovery, whilst depending on balanced elemental resources and appropriate management practices. The work identifies specific interventions to improve nutrient use efficiency, reduce environmental losses, and maintain soil fertility and resilience.
Regional applicability
The paper does not specify a particular geography, so applicability to UK farming is inferred from the international author composition and the universal principles of soil microbial ecology and nutrient cycling. The framework should be relevant to UK arable and mixed farming systems, though implementation would require adaptation to UK soil types, climate, and existing management practices.
Key measures
Soil C:N:P ratios, microbial biodiversity metrics, nutrient recovery efficiency, environmental nutrient losses, soil fertility and resilience indicators
Outcomes reported
The paper proposes a framework integrating soil stoichiometry, microbial biodiversity and crop nutrient demand to improve nutrient recovery and reduce environmental losses. It identifies management interventions to synchronise crop demand with soil C:N:P balance and microbial nutrient cycling.
