There are various types of nano-fertilizers currently being researched and developed. Some examples include:
Carbon-based Nanomaterials: These include carbon nanotubes and graphene oxide, which can enhance nutrient delivery and improve soil health. Silica Nanoparticles: These nanoparticles can be used to deliver micronutrients like zinc and iron to plants. Nano-encapsulated Nutrients: Nutrients can be encapsulated in nanomaterials to protect them from environmental degradation and ensure their gradual release. Polymer-based Nano-fertilizers: These involve using biodegradable polymers to encapsulate and release nutrients in a controlled manner.
