Summary
This narrative review examines the physiological and agronomic mechanisms governing zinc availability and accumulation in crop plants, and synthesises evidence-based strategies to enhance plant zinc content for sustainable agriculture. The authors likely discuss both plant-level factors (root uptake capacity, translocation efficiency, grain/fruit partitioning) and agronomic interventions (soil zinc fertilisation, organic amendments, crop selection) to address zinc malnutrition globally. The paper contributes to understanding how farming practices can improve micronutrient density in staple crops without dependence on mineral fortification.
UK applicability
UK soils are generally adequate in zinc for conventional agriculture, though marginal deficiencies may occur in some calcareous or heavily cropped soils. The review's emphasis on zinc bioavailability and sustainable enhancement strategies may inform UK organic and regenerative farming systems, particularly for nutrient-dense vegetable and cereal production, though direct field applicability would depend on UK-specific soil and climate conditions.
Key measures
Plant zinc concentration, zinc bioavailability, zinc uptake mechanisms, soil-to-plant zinc transfer rates
Outcomes reported
The paper likely reviews physiological mechanisms affecting zinc uptake, translocation and bioavailability in plants, and synthesises agronomic and breeding strategies to enhance plant zinc concentration. Specific metrics reported probably include zinc concentration (mg/kg dry matter) and bioavailability indices across different crop species and management interventions.
