For the proper development and natural growth of plants they require adequate supply of essential nutrients. Nitrogen, phosphorus and potassium are regarded as essential plant nutrients and are consumed in large quantities. To overcome the deficiency of these nutrients in soil additional materials containing N, P and K are added to it in the form of manures. Manures are of two types

(ii) Artificial
Artificial fertilizers are the chemical substances which are added to the soil as to make up the deficiency of essential elements are called fertilizers.

NH2COONH4 → NH2CONH2 + H2O
Out of all, urea is having highest nitrogen content (46.6%). It does not even alter the pH of soil. It can be used for all type of crops.
