Read source ↗ All evidence

Summary

Published in Agronomy (2022), this paper by Reyns et al. synthesises evidence on how irrigation practices affect the bioavailability and uptake of selenium and zinc in cereal crops — two micronutrients of critical importance to human dietary sufficiency. The review likely identifies irrigation as a modulating factor in grain mineral density, potentially through mechanisms including soil leaching, dilution effects, and altered root-zone chemistry. The findings contribute to the growing literature linking agronomic water management with nutritional quality outcomes in staple food crops.

UK applicability

While the review draws on international evidence, the findings are broadly applicable to UK arable systems where supplemental irrigation of cereals is practised, particularly in drier eastern regions; the results may inform discussions around soil selenium deficiency and agronomic biofortification strategies relevant to UK dietary Se shortfalls.

Key measures

Grain selenium concentration (µg/kg or mg/kg); grain zinc concentration (mg/kg); irrigation water volume or regime; soil Se and Zn availability

Outcomes reported

The study examined how differing irrigation regimes influence the uptake and accumulation of selenium (Se) and zinc (Zn) in cereal grains. It likely reports grain mineral concentrations under contrasting water management conditions, with possible reference to yield-dilution or soil bioavailability effects.
