NPK 12-03-43 is a high-potassium, fully water-soluble fertilizer designed to support fruit development, sugar accumulation, and crop quality during mid to late growth stages. This formulation provides 13% nitrogen, 3% phosphorus, and 43% potassium, along with complete solubility and low salt content. It is made from high-purity raw materials and is free from chlorine, sodium, and carbonates, making it safe for crops and fertigation systems.
High potassium content promotes fruit expansion and ripening
100% water soluble with low insoluble residue
Free from chloride, sodium, and carbonates
Crystalline form with uniform particle size (0.1–1.0 mm)
Safe for drip irrigation and foliar spray
Compatible with most modern fertigation systems
Supports higher yield and improved crop quality
Widely used on crops requiring high potassium during fruiting and ripening stages, including:
Grapes, bananas, mangoes, tomatoes, cucumbers, citrus, melons, apples, papayas, pomegranates, and leafy vegetables.
Suitable for fertigation (drip and soil irrigation) and foliar spray. Dissolves quickly without residue and can be absorbed efficiently by roots or leaves. Do not mix with calcium or magnesium-based fertilizers to avoid precipitation.
