Summary
This narrative review examines the multifunctional role of legume root systems in addressing interconnected soil and climate challenges. The authors synthesise evidence on carbon sequestration pathways via root exudates and decomposition, soil structural improvement through rhizodeposition, and mechanisms of salinity mitigation—as suggested by the 2025 publication date and title framing. The review positions legumes as a regenerative farming practice with potential relevance to climate adaptation and soil resilience under increasingly variable precipitation and soil conditions.
Regional applicability
Legume root functions are broadly transferable to United Kingdom arable and mixed farming systems, particularly for spring and autumn-sown legumes (field beans, clover leys). Salinity mitigation findings may have limited immediate application to most UK soils, but carbon sequestration and soil health mechanisms are directly relevant to UK farm sustainability and Net Zero targets. Applicability depends on UK-specific crop varieties, rotation designs, and regional rainfall patterns.
Key measures
Soil organic carbon stocks, root biomass and turnover, soil aggregate stability, microbial community composition, salinity tolerance mechanisms, greenhouse gas fluxes
Outcomes reported
This comprehensive review synthesises evidence on how legume root systems sequester carbon, enhance soil health indicators, and mitigate salinity stress under changing climatic conditions. The paper likely examines mechanisms and quantifies contributions across different agro-climatic zones.
