Q. Which of the following is/are the benefits of Liquid Nano Urea over conventional urea?
1.Liquid urea reduces the subsidy burden of government.
2.Nano Urea has a higher concentration of Nitrogen than the conventional urea.
3.Liquid nano urea has a higher shelf life than conventional urea.
Select the correct answer using the codes given below;
Statements 1 and 3 are correct.
The advantages of Nano urea over conventional urea are,
Higher Efficiency: While conventional urea has an efficiency of about 25%, the efficiency of liquid nano urea can be as high as 85-90%.
Gets Directly absorbed by plant: Conventional urea fails to have the desired impact on crops as it is often applied incorrectly and the nitrogen in it is vaporized or lost as a gas. On the other hand, liquid nano urea is sprayed directly on the leaves and gets absorbed by the plant.
Higher Shelf Life: Liquid nano urea has a shelf life of a year and farmers need not be worried about “caking” when it comes in contact with moisture.
No Burden of Urea Subsidy: Liquid nano urea produced by IFFCO comes in a half-litre bottle priced at Rs 240, and carries no burden of subsidy currently. By contrast, a farmer pays around Rs 300 for a 50-kg bag of heavily subsidized urea.
However, Chemically packaged urea is 46% nitrogen which means a 45 kg sack contains about 20 kg of nitrogen. Contrastingly, Nano Urea sold in 500 ml bottles has only 4% nitrogen (or around 20 gm).
