Macro-element Water-Soluble Fertilizer 20-20-20 consists of uniform granular crystals with a pure texture free of impurities, and its colour can be customised on request. It is fully and rapidly water-soluble, dissolving completely without precipitation, residue or pipeline blockage, and is insoluble in conventional organic solvents. With stable physical and chemical properties and a moderate solution pH, it is a balanced full water-soluble fertilizer widely used for fertigation of field crops, vegetables, fruits and ornamental plants via drip irrigation, sprinkler irrigation and foliar spraying. It evenly supplies nitrogen, phosphorus and potassium, improves crop vigour and addresses weak or uneven seedlings, making it ideal for whole-cycle balanced fertilization and a high-quality raw material for compound liquid and customised formula fertilizers.
