UREA
More than 90% of the world urea production is allocated for agricultural use as nitrogen fertilizer. Urea is either applied directly as straight fertilizer to the soil, or as an ingredient for various tailor made bulk blends. Alternatively urea is also a valuable raw material for compound fertilizers, as well as in solutions for fertigation. Another very important application of urea is the production of chemical compounds, such as formaldehyde resins and adhesives, widely used in the chipboard and furniture industry. Very high technical quality urea is used automobile system for reduction of the nitrogen oxides in the exhaust gases

DAP
Diammonium phosphate (DAP) is a highly water-soluble nitrogen phosphate used in a number of multi-component fertilizer mixtures as well as in directly applied compound fertilizers. Aside from monoammonium phosphate (MAP),it is the world’s most commonly used phosphate fertilizer, with annual production reaching almost 50 million mt. Phosphates are mined in the form of rock phosphate. Phosphates react with sulphuric acid to produce phosphoric acid, which in turn reacts with ammonia. This process converts the poorly water-soluble rock phosphate into a water-soluble phosphate fertilizer that is easily assimilated by plants. DAP is a grey or beige-grey granular substance. DAP is sometimes impregnated with a dust-suppressant oil, giving it a dark brown colouring. To ensure the availability of the best possible product range for global distribution, HELM markets a range of different quality grades and colours from different sources.
