The rising population is increasing food demand, yet actual crop production is limited by the poor efficiency of classical fertilizers. In particular, only about 40–60% of fertilizer nitrogen, 15–20% of phosphorus and 50–60% of potassium are used by crop plants, the rest ending polluting the environment. Nanofertilizers are promising …

Fe nanofertilizers (Fe-NFs) Fe is an essential cofactor for enzymes involved in diverse biological processes in plants. Plants do not have access to an enormous amount of Fe because it is present in insoluble forms in soil. Using very stable and slow-release NFs is a promising strategy to make Fe available to plants.
