Summary
This 2024 review synthesises current understanding of selenium dynamics in agricultural plants, covering uptake mechanisms, transport processes, and toxicity thresholds. The authors evaluate sustainable agronomic and soil management strategies to enhance crop selenium content for biofortification whilst mitigating phytotoxic effects. As suggested by the title and journal scope, the paper bridges soil chemistry, plant physiology, and nutritional outcomes relevant to food systems.
UK applicability
Selenium bioavailability and crop uptake vary significantly with soil type and pH; UK soils are typically low in bioavailable selenium. The review's management strategies—including organic amendment, cultivar selection, and targeted fertilisation—may inform UK policy on micronutrient security and soil health, though local soil testing and agronomic validation would be necessary.
Key measures
Selenium uptake rates, translocation pathways, phytotoxicity thresholds, soil-plant transfer coefficients, and grain/crop selenium concentrations under varying management practices.
Outcomes reported
The study examines how plants uptake, transport, and accumulate selenium; identifies conditions under which selenium becomes toxic to crops; and reviews management strategies to optimise selenium content for human nutrition whilst minimising toxicity risk.
