Features and benefits Urea is an organic compound that occurs naturally. Synthetic Urea is the most widely used nitrogen fertiliser in the world. The wide acceptance of Urea is due to its agronomic acceptability and its low relative cost. Granular Urea is tailored for easy handling, even spreading and blending.

1. Manufacture

Urea is made by combining ammonia and carbon dioxide. Granules of Urea are made by passing the liquid Urea through a fluid bed granulation system, creating a hard and evenly sized granule. Granulated Urea is harder than prilled Urea, therefore creating less fines and dust when handled and transported. Modern Urea products have a stabilising compound added – formaldehyde at between 0.3 and 0.5%. This additive reduces the critical humidity (the humidity level at which Urea absorbs moisture) and greatly improves its handling and storage qualities.

2. Uses

Plants take up nitrogen from the soil in the mineral forms of nitrogen, both ammonium and nitrate before converting it to plant protein nitrogen. Plants vary in their preference to utilise either form of nitrogen. Nitrate is considered the main source because it is mobile in the soil. On addition to the soil, Urea dissolves into the soil solution and is converted to ammonium and then to nitrate.
