This applies to simple ammonium-nitrate based fertilisers which conform with the requirements of the Fertilisers Regulations 1991f1, and to composite fertilisers in which the nitrogen content as a result of the ammonium nitrate is more than 28 per cent in weight (a composite fertiliser contains ammonium nitrate with phosphate or potash, or phosphate and potash).
