China NPK 15-15-30+TE Water-Soluble Fertilizer Suppliers - High-Potassium Fertilizer from Trusted Factory
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.

Frequently Asked Questions (FAQ)
The high potassium content (30% K₂O) is specifically designed for fruiting, swelling, and ripening stages, enhancing fruit size, sugar content, color development, and overall market value.
Yes. It is manufactured with premium raw materials (MAP, MKP, Potassium nitrate) offering 100% complete water solubility with zero residue, ensuring safe application in drip and micro-sprinkler systems.
Chelated trace elements (Fe, Mn, Zn, Cu with EDTA, plus B and Mo) remain readily available for plant uptake across various soil pH levels, preventing nutrient deficiencies and physiological disorders like fruit cracking and blossom-end rot.
For fertigation and drip systems, a dilution ratio of 1000–2000 times is recommended, applied every 7 to 10 days during the peak fruit expansion and ripening periods.
Yes, its weakly acidic formula and high purity allow for rapid leaf absorption via foliar spraying, making it ideal for quick nutrient correction and feeding.
In addition to the standard 25 kg bags, full OEM and ODM customization is supported for bag design, weight specifications, and branding requirements.
