Water Soluble Fertilizer Supplier

Water-soluble NPK fertilizers are crystalline or powder products engineered for complete dissolution in water, with water-insoluble residue typically below 0.05%. They contain nitrogen (as nitrate and/or ammonium), fully water-soluble phosphate (MAP or potassium phosphate-based), and potassium (as potassium nitrate, potassium sulphate, or potassium chloride — with low-chloride grades the standard for high-value crop programs). Trace element (TE) grades include chelated or sulphate forms of iron, zinc, manganese, boron, copper, and molybdenum at agronomically relevant levels.

Standard grades in international trade cover the full crop nutrition cycle: high-P, moderate-N starter grades (e.g. 10-52-10, 13-40-13, 18-18-18) for transplant establishment and root development; balanced growth grades (19-19-19, 20-20-20) for vegetative phases; high-K flowering and fruit grades (12-12-36, 15-5-30, 9-9-27+3MgO) for reproductive stages; and calcium or magnesium-supplemented grades for deficiency-prone crops and crops with high Ca/Mg demand. Grades with sulphate-S (e.g. 15-5-30+3MgO) are popular in programs where both potassium and sulphur are required simultaneously.

We work with buyers to identify the correct grade and program for their crop system, climate, and irrigation infrastructure. Technical support in grade selection, dilution rates, pH management, and irrigation compatibility is available from our sourcing team.
