Summary
Published in Geoderma in 2018, this paper by Gregorich and colleagues examines the connection between soil organic matter and the nutritional quality of food crops. It likely synthesises evidence on how SOM-mediated improvements in soil structure, microbial activity, and nutrient cycling may translate into enhanced mineral and phytonutrient density in harvested food. The paper contributes to an emerging body of literature linking soil health management to human dietary quality, though causal pathways remain complex and context-dependent.
UK applicability
Findings are likely applicable to UK arable and mixed farming systems where SOM depletion through intensive tillage is a recognised challenge; the paper's framing of SOM as a mediator of food nutritional quality is relevant to UK soil health policy debates, including those informed by the Environmental Land Management scheme and commitments to improving soil organic carbon.
Key measures
Soil organic matter content (%); crop nutrient concentrations (minerals, vitamins or phytonutrients, mg/kg); soil biological and chemical indicators
Outcomes reported
The study likely examines relationships between soil organic matter (SOM) levels and the nutrient composition of food crops, assessing how soil carbon and biological activity influence mineral, vitamin or phytonutrient concentrations in harvested produce. It may report correlations between SOM indicators and crop nutritional quality metrics across varying management systems.
