Nano-Fertilizers for Sustainable Crop Production under Changing Climate: A Global Perspective. Nanomaterials improve the productivity of crops and efficiently regulate the delivery of nutrients to plants and targeted sites, guaranteeing the minimal usage of agrochemicals. In conventional agriculture, an excess of fertilizer is applied directly into the soil or sprayed on the leaves, which surpass the nutritional need of the plant. This is because a very low percentage of fertilizer reaches its target site, due to leaching of chemicals, evaporation, drift, hydrolysis, run-off, and photolytic or microbial degradation. This excess of chemical fertilizer negatively affects the nutrient equilibrium of the soil, and causes contamination of local water supplies, due to the leaching of toxic materials into water bodies.
