A 500 ml bottle of nano urea contains 4% nitrogen (w/v). This is equivalent to approximately one bag (45 kg) of conventional urea, according to the government of india.

 A 500 ml bottle of nano urea contains 4% nitrogen (w/v). This is equivalent to approximately one bag (45 kg) of conventional urea, according to the government of india. To produce urea, including nano urea, ammonia and carbon dioxide are reacted. 

Here's a breakdown:

Nano Urea Composition:

A 500 ml bottle of nano urea contains 4% nitrogen (w/v), according to Vikaspedia and IFFCO. This means in 500ml of nano urea, there is 20 ml of nitrogen. 

Equivalent to Conventional Urea:

One 500 ml bottle of nano urea can replace at least one bag of conventional urea. 

Urea Production:

Urea is synthesized by reacting ammonia (NH3) with carbon dioxide (CO2). 

Ammonia and CO2:

To produce 1 ton of urea, approximately 0.73 tons of CO2 are needed, and about 1.5 tons of CO2 are emitted. 

In simpler terms: To make nano urea, you need ammonia and carbon dioxide. A 500ml bottle of nano urea contains enough nitrogen to be equivalent to a standard bag of urea.
