Our nitrogen fertilisers contain ammonium (NH₄) and nitrate (NO₃) with both nitrogen forms being directly taken up by the plants. In arable soils, particularly with low soil temperatures and low mineralization rates, ammonium is converted into nitrate.  This instant accessibility of nitrogen makes nitrate fertilisers the best choice for growers. 

Furthermore, nitrate fertilisers provide growers with the flexibility to optimize both application rates and application timing, thereby increasing nitrogen use efficiency across all crops.
