Triple Super Phosphate (TSP) is a popular source of phosphate nutrient in legumes (peas, lentils and beans), which do not require additional nitrogen fertilisation.
TSP is a highly concentrated and water soluble greyish, granular phosphate fertiliser with a P2O5 availability of more than 46%. To produce TSP, rock phosphate is mined and treated with sulfuric acid. The result is phosphoric acid which reacts again with the rock phosphate to obtain the high concentration of P2O5 in the fertiliser. The active ingredient of TSP is (mono-) calcium phosphate. We can offer different qualities from different origins to meet all customer requirements.

Mono ammonium phosphate (MAP) is used as a complex fertiliser containing nitrogen (11%) and phosphate (52%). Due to its composition it is also called 11-52-0.
MAP is a water soluble mineral phosphate fertiliser, which is used either as a raw material for several complex fertilisers (like NP and NPK) or for direct application. Together with DAP it is the most commonly applied phosphate fertiliser globally. Both are derived from rock phosphate. Rock phosphate is mined mainly in opencast mining. It provides a low water solubility in its natural form, therefore it is unavailable for plants. With the reaction of rock phosphate and sulphuric acid, phosphoric acid is formed. The phosphoric acid is reacted with ammonia to create several ammonium phosphate fertilisers, such as MAP. We trade with all kinds of MAP from different origins, concentrations and in different colours.

Diammonium phosphate in the form of hydrogen phosphate is used in the agricultural sector, where it is used as a compound fertiliser. Because of its nutrient composition, DAP is also called 18-46-0 in the trade.
Diammonium phosphate (DAP) is a highly water-soluble nitrogen phosphate used in a number of multi-component fertiliser mixtures as well as in directly applied compound fertilisers. Aside from monoammonium phosphate (MAP), it is the world’s most commonly used phosphate fertiliser. Phosphates are mined as rock phosphate. Phosphates react with sulphuric acid to produce phosphoric acid, which in turn reacts with ammonia. This process converts poorly water-soluble rock phosphate into a water-soluble phosphate fertiliser 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.
