Biofortification of staple crops with zinc is a strategy for overcoming human zinc deficiency. Agronomists Wang et al. calculated the cost of agronomic biofortification of wheat with zinc in China. Results show that the price is high when zinc is sprayed alone. Whereas the cost is cheaper, from US$ 41 to US$ 108, when zinc is combined with routine pesticide management to reduce labor cost.
