Summary
This 2025 review in Soil and Tillage Research synthesises current knowledge on how legume root systems enhance multiple soil health parameters and support climate adaptation. The authors examine legume-driven carbon sequestration pathways, mechanisms of soil structure improvement, and potential for salinity mitigation—as suggested by the title—across diverse agroecological contexts. The paper positions legumes as a multifunctional component of climate-resilient farming systems, though the extent of direct empirical evidence supporting each claim requires examination of the full text.
UK applicability
UK temperate farming systems routinely integrate pulses and nitrogen-fixing crops into rotations; findings on carbon sequestration and soil structure improvement are likely transferable to British conditions, particularly in mixed and organic systems. However, salinity mitigation mechanisms may have limited direct applicability except in coastal or salt-affected soils in the south-east and East Anglia.
Key measures
Carbon sequestration rates, soil organic matter, soil microbial diversity, soil structure indicators, salinity tolerance metrics, root biomass and exudate production
Outcomes reported
This comprehensive review synthesises evidence on how legume root architecture and function contribute to soil carbon stocks, microbial community health, and salinity tolerance in agricultural systems facing climate change. The paper examines mechanisms linking belowground legume biology to above-ground agronomic and environmental outcomes.
