Summary
This paper investigates the comparative effectiveness of different zinc and selenium fertiliser forms for biofortification of wheat grain, published in the Journal of Plant Nutrition and Soil Science (2016, vol. 179, pp. 248–255). Cattani and colleagues likely assess whether foliar or soil applications of Zn and Se are more effective at elevating grain micronutrient concentrations, with implications for addressing dietary deficiencies through agronomic biofortification. The findings contribute to the evidence base on practical fertiliser strategies that can improve the nutritional quality of staple cereal crops without requiring genetic modification.
UK applicability
Although the study was likely conducted in Italy under Mediterranean or northern Italian soil and climate conditions, the principles of agronomic biofortification of wheat with Zn and Se are directly relevant to UK arable systems, where selenium deficiency in soils is well documented and UK wheat grain Se concentrations are frequently below nutritionally adequate levels.
Key measures
Grain Zn and Se concentration (mg/kg); fertiliser form (foliar vs soil-applied); possibly grain yield (t/ha) and nutrient use efficiency
Outcomes reported
The study likely measured grain zinc and selenium concentrations in wheat under different fertiliser application strategies, comparing foliar versus soil-applied forms and their relative effectiveness at increasing micronutrient accumulation in grain.
