Rosier produces straight nitrogen and phosphate fertilisers. Calcium ammonium nitrate, or more simply CAN, is an effective nitrogen fertiliser suitable for use with all sorts of plants and on all types of soil. It is an easy-spreading product. Another straight N fertilizer is ASN. Next to 26 % Nitrogen, it contains 14 % S. Triple ( T.S.P.) and Single Super Phosphates ( S.S.P.) are both straight phosphate fertilisers. Phosphate is extremely soluble, so both these granular fertilisers are fast-acting. On request we can produce them with extremely low cadmium content.
