Agronomic biofortification of crops to fight hidden hunger in sub-Saharan Africa

This article in the Global Food Security journal discusses the effectiveness of agronomic biofortification – the application of mineral micronutrient fertilizers to soils or plant leaves to increase micronutrient contents in edible parts of crops – and it’s potential to fight hidden hunger. There is evidence that agronomic biofortification can increase yields and the nutritional quality of staple crops, but there is a lack of direct evidence that this leads to improved human health. »
