Nanofertilizers towards sustainable agriculture and environment

Precise nutrient management of crops and soil fertility will be a major challenge worldwide in the coming decades because current agricultural practices rely predominantly on chemical fertilizers. The use of conventional fertilizers suffers from low crop nutrient efficiency, negative impacts on the environment, and high loss of water bodies. Nano-biotechnology is emerging as a promising alternative technique and has the potential to revolutionize agricultural systems by delivering nutrients to crops in a controlled release manner. Engineering nanoparticles-based nanofertilizers offer benefits in crop nutrition management by enhancing abiotic stress tolerance and improving agricultural productivity. This review focuses on the design, contribution, and interaction of nano-enabled fertilizers with edible plants based on very recent studies. Also, the review conveys the role of macronutrient, micronutrient-based nanofertilizer as well as nano-biofertilizer towards the development of smart and sustainable future agriculture.
