Explore the innovative use of nano fertilizers like nano DAP in modern agriculture, their benefits, and their impact on crop productivity and the environment.
What does 'nano' refer to in nano DAP fertilizers used in agriculture?
Explanation: 'Nano' in nano DAP means particles smaller than 100 nanometers, which enhances absorption by plants. Natural minerals and organic manure are traditional materials, not specific to 'nano' technology. Large granular pellets describe conventional fertilizers, not nano forms.
What is one main advantage of using nano DAP over conventional DAP fertilizers?
Explanation: Nano DAP offers higher efficiency, allowing farmers to use less fertilizer for similar or better crop yields. Nano DAP does not eliminate the need for irrigation, control weeds, or provide full disease resistance.
How can using nano DAP contribute to environmental protection in agriculture?
Explanation: Nano DAP's higher uptake efficiency reduces the excess fertilizer lost to runoff, protecting water sources. It does not make fertilizers non-biodegradable or increase heavy metals, and it does not replace pest control.
How do plants most efficiently absorb nutrients from nano DAP fertilizers?
Explanation: Nano-sized particles can be absorbed more efficiently by both leaves and roots. Traditional fertilizers are usually absorbed mainly by roots, and neither stems nor whole pellets are direct routes of nutrient uptake.
Which potential challenge is associated with the widespread adoption of nano fertilizers like nano DAP?
Explanation: The long-term impact of nano fertilizers on the environment and soil health requires more research. Zero cost, permanent fertility, and lack of regulation are unrealistic or incorrect statements.
