Extensively used nitrogenous fertiliser is A. ammonium nitrate B. Urea C. ammonium sulphate D. nitro-lime

ammonium nitrate
Urea
ammonium sulphate
nitro-lime

The correct answer is A. ammonium nitrate.

Ammonium nitrate is a common nitrogenous fertilizer that is used to increase crop yields. It is a white, crystalline solid that is soluble in water. Ammonium nitrate is produced by the reaction of ammonia with nitric acid. It is a relatively inexpensive fertilizer and is easy to apply. However, ammonium nitrate can be explosive if it is not handled properly.

Urea is another common nitrogenous fertilizer. It is a white, crystalline solid that is soluble in water. Urea is produced by the reaction of ammonia with carbon dioxide. It is a more expensive fertilizer than ammonium nitrate, but it is less likely to be explosive.

Ammonium sulfate is a common nitrogenous and sulfurous fertilizer. It is a white, crystalline solid that is soluble in water. Ammonium sulfate is produced by the reaction of ammonia with sulfuric acid. It is a relatively inexpensive fertilizer and is easy to apply. However, ammonium sulfate can be acidic and can damage plants if it is not used properly.

Nitro-lime is a mixture of calcium nitrate and calcium carbonate. It is a grayish-white powder that is soluble in water. Nitro-lime is produced by the reaction of calcium nitrate with calcium carbonate. It is a relatively expensive fertilizer and is not as easy to apply as ammonium nitrate or urea. However, nitro-lime is less likely to be explosive and is less likely to damage plants.
