Product Features
1. Complete Water Solubility
The fertilizer is fully soluble in water, dissolves quickly, and leaves no residue, making it suitable for efficient fertilization methods such as drip irrigation, spray irrigation, and foliar spray, with high nutrient absorption efficiency.
2. Wide Applicability
Suitable for various crops, including vegetables, fruits, flowers, grain crops (e.g., wheat, corn), and cash crops (e.g., cotton, rapeseed), and adaptable to different soil types.
3. Promotes Growth and Increases Yield
The balanced nutrient supply supports healthy crop growth, enhances photosynthesis, improves yield and quality, and boosts crop resilience (e.g., drought and disease resistance).
4. Environmentally Friendly and Safe
Free of chloride ions, sodium ions, and heavy metal residues, it meets the standards for green agriculture and non-polluting agricultural products, making it soil- and environment-friendly.
5. Flexible Application
Can be used as base fertilizer, top dressing, or foliar spray to meet the nutrient needs of crops at different growth stages.

Application&Fertilization Methods
Suitable Crops
1. Grain Crops: Apply during the tillering and jointing stages for wheat and rice to promote tillering and sturdy stems; apply during the bell stage for corn to promote ear development.
2. Fruits and Vegetables: Apply during the flowering and fruiting stages for tomatoes and cucumbers to promote fruit expansion; apply before flowering and during fruit expansion for apples and grapes to improve fruit quality.
3. Cash Crops: Apply during the budding and bolling stages for cotton to increase boll setting rate; apply during the bolting stage for rapeseed to enhance branching and oil content.
Fertilization Methods
1. Base Fertilizer Application
Evenly apply NPK19-19-19 water-soluble fertilizer to the soil before planting to provide long-term nutrient support, promoting root development and seedling growth.
2. Top Dressing Application
Apply during vigorous growth stages (e.g., tillering, flowering, fruiting) to supplement nutrients, promoting healthy growth and increased yield.
3. Foliar Spray
Dilute and spray on crop leaves to quickly replenish nutrients, especially suitable for correcting nutrient deficiencies or during critical growth stages.
4. Drip Irrigation/Fertigation
Dilute and apply through drip irrigation systems, suitable for large-scale farmland or facility agriculture, improving fertilization efficiency.
