Kimiadaran Kavir proudly announces the successful localization of triple superphosphate (TSP) fertilizer production with an annual capacity of 100,000 tons. TSP—commonly referred to as “black fertilizer”—is among the most phosphate-rich chemical fertilizers available, providing an efficient and high-quality solution for modern agricultural needs. The production process involves two stages. In the first stage, sulfuric acid reacts with phosphate rock to produce phosphoric acid. In the second stage, gypsum is separated and the acid is concentrated, then reapplied to phosphate rock to synthesize TSP. The final product is manufactured in granular form (GTSP), enabling uniform field application. This domestically produced TSP contains more than 46% available P₂O₅, with 90% of the phosphorus being water-soluble, allowing for rapid plant uptake. It is also enriched with essential nutrients, including 15% calcium, 2% sulfate, and 1% iron—enhancing plant strength and increasing resistance to pests and diseases. Crucially, the product is free from hazardous heavy metals—especially cadmium and arsenic—which are commonly found in imported alternatives. This ensures greater environmental safety and compliance with international agricultural standards. TSP is suitable for all types of crops, including field, horticultural, and vegetable products. It can be applied using two primary methods: Broadcast application with soil incorporation: Typically used for general field distribution. Band placement near seeds during planting: A more efficient method that significantly improves phosphorus availability and uptake. The facility currently operates under a production license for 100,000 tons per year, with the ability to scale up output to 200,000 tons. By localizing the production of this strategic fertilizer, Kimiadaran Kavir has successfully reduced the need for 250,000 tons of annual imports, resulting in over $37 million in savings of foreign exchange each year. This milestone highlights Kimiadaran Kavir’s ongoing commitment to research and development, industrial self-reliance, and the sustainable advancement of Iran’s agricultural sector.
