Question

Can urea by universally used for all crops in all stages? Justify.

Answer 1

The agricultural industry widely uses urea, a white crystalline solid containing $46$ % nitrogen as an animal feed addictive and fertilizer. Here, we will focus on its role as a nitrogen fertilizer. In the past decade, urea has surpassed and nearly replaced ammonium nitrate as fertilizer.

Urea is a plant metabolite derived either from root uptake or catabolism of arginine by arginase. In agriculture, Urea nitrogen enters the plant either directly or in the form of ammonium or nitrate after urea degradation by soil, microbes. Hence, we can say that urea is universally used for all crops in all stages and it is essential for the growth of the plants.
