Super Potassium Humate Flakes / Powder FAQ

Answer: No adverse side effects occur with proper dosage. Key notes for safe long-term use:
  1. It promotes beneficial soil microbial activity and improves soil structure over time, without causing compaction or nutrient imbalance.
  2. Avoid excessive application—overdosing may lead to overly vigorous root growth but slower above-ground plant development.
  3. For saline-alkaline or heavy-metal contaminated soils, combine with soil testing and apply in split doses to prevent potential heavy-metal accumulation.
  4. Follow recommended dosage ranges (base + topdressing) for sustained soil and crop health.
  • Flakes: Slower dissolution (10-15 mins stirring or overnight soaking for large-scale use), cost-effective, suitable for base application/soil incorporation.
  • Powder: Instant dissolution (5 mins), convenient for drip irrigation/foliar spraying. Choose based on application method: flakes for base fertilization; powder for topdressing (drip/foliar) or time-sensitive scenarios.
No. This product is not compatible with fertilizers (NPK, calcium/magnesium-based) or pesticides. Maintain a ≥72-hour interval between application and other agri-inputs. For blending needs, use our complementary product: Mineral source humic fulvic fertilizer (formulated for compatibility).
  1. Saline-alkaline soil: Increase dosage by 20-30% (base + topdressing) to enhance acid-adjusting and alkali-inhibiting effects;
  2. Sandy soil: Increase by 15-25% to maximize water-locking capacity;
  3. Clay soil: Reduce by 10-15% (avoids excessive moisture retention);
  4. Fertile soil: Reduce by 10-20% to prevent nutrient leaching.
  1. Soil improvement effects (loosening, water retention): Visible in 2-4 weeks (e.g., saline-alkaline soil EC value decreases by 15-20%);
  2. Crop growth effects (root development, vigor): 1-2 weeks for foliar spray/drip irrigation;
  3. Yield and quality improvement: Manifested in critical stages (flowering, fruit enlargement) or at harvest (yield +11.5-35%, sugar content +7-30%).
Yes. It fully complies with organic agricultural standards, with key certifications:
  • CERES EU/NOP (organic input certification);
  • ISO Quality Management System Certification;
  • EU REACH Compliance. It can be directly used in organic crop cultivation without violating certification requirements.
  1. Foliar spraying: Dilute 1:500-800 (w/v) with clean water (pH 6.0-7.5), spray on both leaf sides in early morning or late afternoon (avoid direct sunlight); 
  2. Drip irrigation: Dilute 1:200-300 (w/v), stir thoroughly until fully dissolved, filter with 120-150 mesh screen to prevent nozzle clogging;
  3. Key note: Flakes need pre-soaking (10-15 mins) before dilution.
Storage conditions: Keep in a dry, cool (15-25℃), well-ventilated area; avoid moisture, direct sunlight, and contact with strong acids/alkalis. Shelf life: 24 months in original sealed packaging. Open packages should be used within 3 months and resealed tightly after each use.
  1.  Higher humic acid content (65-70% vs. 50-60% for ordinary products);
  2.  Large molecular weight (2-3x stronger water-locking and soil improvement effects);
  3.  Strict organic certifications (CERES EU/NOP, REACH) for global market access;
  4.  Proven results (11.5-35% yield increase in domestic field trials, applicable to problematic soils like saline-alkaline/sandy soil).
  1. Avoid direct contact with crop roots (dig trenches/holes 15-20 cm away during topdressing) to prevent root burn;
  2. Wear gloves and a mask when operating, rinse with water immediately if it comes into contact with skin/eyes;
  3. Keep away from children and pets;
  4. Do not mix with strong acidic/alkaline substances (e.g., concentrated sulfuric acid-based fertilizers) to avoid flocculation.
