Urea is the most popular and economical of all nitrogen-based fertilisers used worldwide. It is exceptionally versatile and can be used in a range of environmental conditions on a wide variety of crops. Urea is also a major raw material for industrial products, including melamine.
AMMONIA AND PHOSPHATES
Ammonia is the chief raw ingredient in the production of urea and is used in the manufacture of other fertiliser products. It may also be applied directly to moist soils to provide high nitrogen content for growing wheat, barley and oilseed rape. Besides its agricultural uses, ammonia is important as a raw material in a number of industrial applications, such as the manufacture of synthetic materials.
