Recent advancements in agricultural technology focus on improving fertiliser efficiency. Traditional fertiliser practices have raised concerns over sustainability. Excessive use of chemical fertilisers can harm soil health and the environment. Researchers are exploring biodegradable solutions to enhance nutrient use while minimising negative impacts. A notable development is the creation of a nanocoating material that optimises fertiliser performance.
What is Nanocoating?
Nanocoating involves applying a thin layer of nanomaterials to enhance product properties. In this case, the coating is made from biodegradable materials like chitosan and lignin. These materials are reinforced using nanoclay to create a hydrophobic layer. This layer controls the release of nutrients from fertilisers, ensuring they are available when crops need them.
Mechanism of Action
The hydrophobic nature of the nanocoating slows the release of nutrients. This means that chemical fertilisers interact less with the soil, water, and microbes. The controlled release aligns with crop requirements, reducing the risk of nutrient leaching and enhancing uptake by plants.
Benefits of Biodegradable Coatings
Using biodegradable materials for coating fertilisers offers several advantages. It reduces the environmental footprint compared to conventional fertilisers. The coated fertilisers maintain their effectiveness while being less harmful to the ecosystem. Moreover, they are designed to break down naturally, leaving no harmful residues.
Research and Development
The research conducted by scientists from the Institute of Nano Science and Technology (INST) marks the innovative coating process. They utilised a drum rotor method to ensure a uniform application of the coating. This method enhances the mechanical stability of the fertilisers, making them suitable for transportation and storage.
Impact on Agriculture
The introduction of slow-release fertilisers can impact agricultural productivity. By reducing the recommended fertiliser dose, farmers can achieve higher yields. This efficiency not only benefits individual farmers but also contributes to the national economy. Improved crop output from lower input costs can enhance the socio-economic conditions of farming communities.
Future Implications
The development of such nanocoating technologies points towards a sustainable future in agriculture. It opens avenues for further research into eco-friendly farming practices. As the world faces challenges like climate change and food security, innovative solutions like these are essential for sustainable development.

Answer Hints:
1. Examine the role of biodegradable materials in sustainable agriculture practices.
Biodegradable materials play important role in sustainable agriculture by reducing environmental impact and enhancing soil health. They minimize chemical residues and prevent soil degradation associated with conventional fertilizers. Using materials like chitosan and lignin for coating fertilizers ensures that nutrients are released in alignment with crop needs, promoting better uptake and reducing waste. Additionally, these materials break down naturally, enriching the soil without harmful effects. This aligns with sustainable practices, encouraging a healthier ecosystem while supporting agricultural productivity.
2. Critically discuss the impact of chemical fertilisers on soil health and ecosystem balance.
Chemical fertilizers, while boosting crop yields, can harm soil health and ecosystem balance. Their excessive use leads to nutrient leaching, soil acidification, and loss of microbial diversity. This disrupts soil structure and fertility, making it less resilient to pests and diseases. Additionally, runoff from fertilized fields can contaminate water bodies, leading to eutrophication and harming aquatic ecosystems. Thus, while they offer short-term benefits, long-term reliance on chemical fertilizers threatens sustainable agriculture and environmental integrity.
3. Analyse the significance of nanotechnology in enhancing agricultural productivity.
Nanotechnology enhances agricultural productivity by improving nutrient delivery systems, such as slow-release fertilizers. By utilizing nanocoatings, nutrients are released in a controlled manner, aligning with plant growth stages and reducing waste. This technology increases nutrient use efficiency, allowing for lower fertilizer doses while achieving higher yields. Furthermore, nanomaterials can improve soil health by promoting beneficial microbial activity. The integration of nanotechnology in agriculture not only boosts productivity but also supports sustainable practices, addressing concerns over environmental impact and resource management.
4. Point out the socio-economic benefits of adopting slow-release fertilisers for farmers.
Adopting slow-release fertilizers offers important socio-economic benefits for farmers. By reducing the recommended fertilizer dose, farmers can lower input costs while maintaining or increasing crop yields, enhancing their profitability. Improved nutrient efficiency leads to better soil health, ensuring sustainable production over time. Additionally, higher yields contribute to food security, benefiting local and national economies. This transition also supports environmental sustainability, potentially attracting eco-conscious consumers and markets. Overall, slow-release fertilizers can improve the livelihoods of farming communities while promoting agricultural resilience.
