Biofortification of Fe and Zn in wheat grain on acid and calcareous soils

Wheat (Triticum spp.) is the most important bread grain and an important source of food and essential minerals and vitamins for humans, especially in developing countries where bread is the basic or the most common type of food. Low concentrations of Fe and Zn in wheat grain leads to many health problems and even deaths, mostly of young children and women. The lack of these micronutrients in human diet highlights the need to increase their levels in grain. The simplest and fastest way is biofortification of wheat, the application of Fe and Zn in the form of fertilizers in the soil and foliar or a combination thereof, but their content is determined by the influence of a large number of grain genotype, soil conditions, physical and soil chemical properties, types of fertilizers, and partly with their content and availability in the soil where they are grown. In acidic soils, heavy metals are more soluble and mobile and available to plants than in calcareous soils, therefore, the concentration of Fe and Zn in wheat grain are greater in more acidic than in alkaline soils.
