NPK 15-15-30+TE Water-Soluble Fertilizer from China Suppliers & Factory for High-Yield Crop Production
Product Overview
NPK 15-15-30+TE Water-Soluble Fertilizer is a high-potassium formula developed for fruiting and quality improvement stages. With elevated potassium content, it plays a key role in fruit enlargement, sugar accumulation, and color development, making it widely used in high-value crops and intensive farming systems.
Manufactured using high-purity raw materials such as monoammonium phosphate (MAP), monopotassium phosphate (MKP), and potassium nitrate, the product ensures complete water solubility, fast dissolution, and zero insoluble residue, allowing safe and efficient use in drip irrigation, foliar spraying, and fertigation systems.
The formula is enriched with chelated trace elements (EDTA-Fe, Mn, Zn, Cu, plus B and Mo), supporting balanced plant nutrition and reducing the risk of physiological disorders caused by nutrient deficiencies.
With its mildly acidic solution, this fertilizer improves nutrient availability and uptake efficiency, contributing to better crop performance, improved fruit quality, and higher market value.
