The study of nanotechnology has the potential to fundamentally alter how humans perceive and influence change in a variety of fields, including mass transfer, biomedicine, agriculture, and water management, among others. The word “Nano” refers to a type of technology that uses tiny particles that can be seen with the naked eye. Working at this size enables more successful creative solutions to special situations. For instance, employing zeolites and nanoclays to improve soil fertility and quality can increase fertiliser effectiveness. The development of intelligent seeds coated with nano-polymers and timed for germination under favourable conditions seems promising. Crops are often categorised according to their nutrient needs when precision farming inputs are used, and with the help of a Nano-biosensor and a satellite system, the distribution of nutrients may be tracked more precisely than with current techniques. This also highlights the creation of nano-herbicides to deal with weed control. Studies exist that show how efficient nano-fertilizers are in increasing the productivity and efficiency of the nutrients, lowering soli toxicity, and reducing potential contamination-related problems. Therefore, nanotechnology has great promise for sustainable agriculture, particularly in underdeveloped nations.
