Categories

Granular urea is one of the most widely used nitrogen-based fertilizers, containing 46% nitrogen. It plays a crucial role in modern agriculture by providing essential nutrients to crops, boosting yields, and enhancing soil fertility. Manufactured in granular form with particle sizes ranging from 1 to 4 mm, it offers excellent solubility, ensuring rapid absorption by plants.

Beyond its agricultural applications, granular urea is also widely used in industrial sectors, including chemical manufacturing, animal feed production, and energy generation. Its high efficiency, cost-effectiveness, and ease of storage make it a preferred choice in global markets.
