TSP is a highly concentrated and water soluble greyish, granular phosphate fertilizer 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 gets reacted again with the Rock Phosphate in order to obtain the high concentration of P2O5 in the fertilizer. The active ingredient of TSP is (Mono-)Calcium Phosphate. HELM offers different qualities from different origins to meet all customer demands.

Examples of applications

Until the 1960s, TSP was the most common fertilizer in the US. Since then, Nitrogenphosphate fertilizer (i.e. MAP and DAP) became more and more popular on the American market. TSP is a highly concentrated phosphate fertilizer, which is used either in direct application or as a raw material in the production of complex fertilizers and blends with a high concentration of P2O5. Over 90% of the total P in TSP is water soluble, so it becomes rapidly available for plant uptake.
