Urea is the most important nitrogenous fertiliser in the country because of its high N content (46%N). Besides its use in the crops, it is used as a cattle feed supplement to replace a part of protein requirements. It has also
numerous industrial uses notably for production of plastics. Although urea often offers farmers the most nitrogen for the lowest price on the market, special steps must be taken when applying urea to the soil to prevent the
loss of nitrogen through a chemical reaction.
