This study is a comprehensive global meta-analysis assessing the contribution of fertilization (with a wide set of nutrients) to the nutritional quality of food crops, an aspect little studied so far, compared to yield. It shows that fertilizer application improves crop yield and nutritional quality by varying degrees, depending on nutrient and crop species, with vegetables being the most responsive. It paves the way towards a quantitative understanding of nutrient management programs and responsible plant nutrition solutions that foster the sustainable production of nutritious and healthy crops for human consumption.
