News:

Scientists have developed a biodegradable, hydrophobic nanocoating material that can slow the release of chemical fertilisers, boosting their efficiency and promoting sustainable agriculture.

This innovation aims to improve nutrient use efficiency, reduce fertilizer doses, and mitigate environmental impacts associated with excessive chemical fertiliser use.

It is developed by the Institute of Nano Science and Technology (INST), Mohali.

Mechanism of the Nanocoating:

1. Hydrophobic Properties: By adjusting the hydrophobicity of the coating, researchers can control the release rate of nutrients to match the specific growth phases of crops.
2. Stable Coordination Bonds: The coating employs anionic clay as a reinforcement, forming stable coordination bonds that enhance mechanical stability and prevent premature nutrient release.
3. 3D Nanostructure Advantage: The 3D structure of the natural polymers in the coating, including self-assembling amyloid fibrils, provides durability, biodegradability, and efficient nutrient encapsulation.
