what is nano fertilizer and it’s advantage

Nano Fertilizer :

Nano-sized fertilizers by combining components such as ammonium humate, ammonia, peat, plant wastes, and synthetic fertilizers. One method is the deposition of urea onto calcium cyanamide to produce a nano-sized nitrogen (N) fertilizer. It is water soluble fertilizer  and it also used in  fertigation.

Advantage of Nano Fertilizer :

1. Nano fertilizers provide crop plants with nutrients in a controlled and gradual manner, unlike chemical fertilizers, which release nutrients rapidly and spontaneously.
2. Nanoparticles exhibit significantly increased uptake due to their ability to freely pass through nano-sized pores, molecular transporters, and root exudates.
3. Within the plant, nanoparticles may pass through plasmodesmata that results in effective delivery on nutrient to sink sites.
4. Because nano fertilizers experience minimal losses, they can be applied in smaller quantities compared to synthetic fertilizers, which are typically used in larger amounts
5. Nano-fertilizers are more efficacious in terms of nutrients absorption and utilization owing to considerably lesser losses in the form of leaching and volatilization.

Limitation :

1. Laws and regulations concerning nano-fertilizers and managing associated risks are the main issues limiting their use.
2. Producing and making nano-fertilizers available in the right amounts is challenging. They also tend to be more expensive, making it difficult to widely adopt them for crop production in different environmental conditions worldwide.
3. Another big problem with nano fertilizers is that there aren’t recognized ways to make them or set standards for their production. This means the same nanomaterial might have different effects in different environments.
