Description:
1. High-Efficiency Nutrition: 13% N + 46% K₂O; promotes growth, photosynthesis, fruit sugar/water content, and quality.
2. Enhanced Stress Resistance: Enhances drought, cold, lodging, pest/disease resistance; reduces premature senescence; ensures stable yields.
3. Suitable Crops: Suitable for chlorine-sensitive crops such as tobacco, tomatoes, grapes, citrus, apples, watermelons, melons, cowpeas, chili peppers, potatoes, etc.
4. Application Timing: Mid-to-late stage topdressing, especially during fruit expansion (e.g., grape veraison, late apple growth). Foliar spray remedies N/K deficiencies and enhances disease resistance.
5. Caution: Excessive use during the coloring period (e.g., tomatoes, apples) may hinder proper fruit coloration; use with caution
6. Residue-Free: Fully water-soluble; no soil pollution.
Packaging: 25kg/bag, 50kg/bag, 1 ton/bag, 1.2 tons/bag.
