Triple Super Phosphate (TSP)
Triple Super Phosphate is a popular source of Phosphate nutrient used in the commercial production of legumes (peas, lentils and beans) which do not require additional Nitrogen fertilization.
TSP is a highly concentrated and water soluble greyish, granular phosphate fertilizer with a product label of 0-46-0. To produce TSP, Rock Phosphate is mined and treated with Sulfuric Acid. HELM offers different qualities from different origins to meet all customer demands.
Until the 1960s, TSP was the most common fertilizer in the US. Since then, Nitrogen-phosphate fertilizer (i.e. MAP and DAP) production gradually displaced TSP production in the US market. TSP is a highly concentrated phosphate fertilizer that is used either in direct application or as a raw material in the production of complex fertilizer. Over 90% of the total P in TSP is water soluble, so it becomes rapidly available for plant uptake.
