ABSTRACT
Fertilizers are routinely applied to crops to enhance their quality and productivity. However, due to their poor nutrient use efficiency, an alternative approach was sought to minimize environmental impacts. Nanotechnology was identified as a promising interdisciplinary approach and has been augmented in agriculture to promote the slow and controlled release of fertilizers. Different types and forms of nanofertilizers (NFs) have enabled us to enhance the nutrient use efficiency of fertilizers. Mainly, NFs are found as macronutrients and micronutrients and are delivered either as a carrier, intercalated, or encapsulated products. Furthermore, their astonishing physicochemical properties and environmental conditions of nanoparticles (NPs) make NFs show different modes of release behaviors and kinetics. Therefore, this chapter mainly focuses on the application of NFs in crop productivity, highlighting their types, modes of delivery, and release behavior.
