4. Present the perspective of Nano-Fertilizers for Sustainable Crop Production under Changing Climate in the country. (250 words)
Why the question:
Union Minister for Chemicals and Fertilizers Shri D.V. Sadananda Gowda said, by 2023 India will be self-reliant in the production of fertilizers as under “Atma Nirbhar Bharat” programme new fertilizer manufacturing units are being setup with an investment of Rs 40,000 crore in the country to reduce dependency on import.
Key Demand of the question:
Explain in detail the perspective of Nano-Fertilizers for Sustainable Crop Production under Changing Climate in the country.
Present – Weigh up to what extent something is true. Persuade the reader of your argument by citing relevant research but also remember to point out any flaws and counter- arguments as well. Conclude by stating clearly how far you are in agreement with the original proposition.
Structure of the answer:
Start by explaining about nano-fertilisers in general and their definition in specific.
Nanotechnology, which utilizes nanomaterial’s of less than 100 nm size, may offer an unprecedented opportunity to develop concentrated sources of plant nutrients having higher-absorption rate, utilization efficacy, and minimum losses. Nano fertilizers are being prepared by encapsulating plant nutrients into nanomaterials, employing thin coating of nanomaterials on plant nutrients, and delivering in the form of nano-sized emulsions. Nano-pores and stomatal openings in plant leaves facilitate nanomaterial uptake and their penetration deep inside leaves leading to higher nutrient use efficiency (NUE). Nanofertilizers have higher transport and delivery of nutrients through plasmodesmata, which are nanosized (50–60 nm) channels between cells.
Discuss how they may lead to higher crop production and sustainable agro systems amidst changing climates of the world.
Conclude with its importance and way forward.
