Its utilization is increasing steadily, it being the preferred nitrogen fertilizer worldwide. It is used in solid fertilizer, liquid fertilizer, formaldehyde resins and adhesives.

Rouelle first discovered urea in urine in 1773. His discovery was followed by the synthesis of urea from ammonia and cyanic acid by Woehler in 1828. This is considered to be the first synthesis of an organic compound from an inorganic compound. In 1870, Bassarow produced urea by heating ammonium carbamate in a sealed tube in what was the first synthesis of urea by dehydration. The chemical formula of, NH2CONH2, indicates that urea can be considered to be the amide of carbamic acid NH2COOH, or the diamide of carbonic acid CO(OH)2.

Fertilizer is generally defined as “any material, organic or inorganic, natural or synthetic, which supplies one or more of the chemical elements required for the plant growth”. The main aim of the fertilizer industry is to provide the primary and secondary nutrients which are required in macro quantities. Primary nutrients are normally supplied through chemical fertilizers. They are chemical compounds containing one or more of the primary nutrients and are generally produced by chemical reactions. Whatever may be the chemical compounds, its most important ingredient for plant growth is the nutrient content. The primary nutrients are Nitrogen, Phosphorus and Potassium. However, their concentration in a chemical fertilizer is expressed as a percentage of total nitrogen (N), available phosphate (P2O5) and soluble K2O. The grade of a fertilizer is expressed as a set of three numbers in the order of percent N, P2O5 and K2O. If a nutrient is missing in a fertilizer, it is represented by a zero. Thus ammonium sulphate is represented by 20.6-0-0.

Plants & other vegetation are no doubt living beings & thus, they also requires certain foods to grow. The fertilizers are that materials which are added to the  soil, to  supply nutrients for the survival & formal growth of  plants. The fertilizers promote growth of plants. The fertilizers promote their growth fruitfully.  The elements that constitute these essential plant foods are as follows:-

i)   Nitrogen,

ii)  Phosphorous

iii) Potassium

iv)  Calcium

v)   Magnesium

vi)  Sulfur

vii) Iron

viii) Manganese

ix)  Copper
