A chemical or natural substance added to soil or land to increase its fertility is known as Fertilizer.

The fertilizers are classified on the basis of the nature of nutrient elements like Nitrogen, phosphorus, potassium (NPK) present chemically in the compounds. There are various nitrogenous chemical fertilizers like ammonium sulphate, calcium ammonium nitrate, basic calcium nitrate, calcium cyanamide (nitrolium), urea etc.  Obviously these fertilizers supply nitrogen to the soil.
