Q. Consider the following statements:
1.Nano-urea is applied to the soil.
2.Nano-urea is a liquid fertilizer developed by IFFCO (Indian Farmers Fertilizer Cooperative Limited) in India.
3.Nano-urea reduces greenhouse gas emissions and groundwater pollution.
How many of the statements given above are correct?
Answer: B
Notes:
Explanations –
Statement 1 is incorrect. Nano-urea is not applied to the soil like conventional urea. Instead, it is sprayed directly onto the leaves of plants at specific stages of growth, as this method is believed to make nitrogen more bioavailable to the plants.
Statements 2 and 3 are correct. Nano-urea is a liquid fertilizer developed by IFFCO in India as a technological innovation aimed at reducing conventional urea usage and improving nitrogen efficiency. Nano-urea has the potential to reduce greenhouse gas emissions (e.g., nitrous oxide) and groundwater pollution caused by the overuse of conventional urea, as it requires smaller quantities for application.
