ABSTRACT
Micronutrients are required in a very low amount compared to macronutrients, such as nitrogen and phosphorous, but are critical for the plant productivity, growth and development. Furthermore, it is important to note that the requirement of micronutrients for both humans and plants is complementary, thus, an adequate amount of micronutrient fertilization in the agriculture could also help to meet the necessary nutrient requirements of the human diet. Because of high surface area to volume size ratio, nanomaterials require less volume compared to their bulk material. Therefore, nanoparticles consisting of micronutrient elements are increasingly being tested for crop fertilization.
