CaseHigh-Yield Wheat Cultivation in Saline-Alkaline Soil (Gaotang, Shandong)
Location: Gaotang County, Liaocheng City, Shandong Province (concentrated saline-alkaline soil area) Crop: Winter Wheat Application Scheme: Apply high-purity potassium humate (65-70% humic acid) as base fertilizer, supplemented with the same type of product for topdressing. Uniformly spread before sowing, plow 15-20 cm deep for soil mixing; apply via drip irrigation during the wheat regreening stage for topdressing. Core Results: Broke the “low-yield curse” of saline-alkaline soil—wheat yield reached 746 kg per mu (≈11.2 tons/ha), an increase of 100 kg per mu compared to traditional fertilization. The wheat growth cycle returned to normal, with robust plants and plump ears, effectively alleviating the “early maturity and low yield” caused by saline-alkaline stress. Core Value: Leveraging the acid-adjusting and alkali-inhibiting properties of high humic acid content, it improves soil structure, enhances water and nutrient retention capacity, and strengthens wheat stress resistance—achieving a win-win for saline-alkaline soil remediation and high crop yield.

FAQ
1. Is there any side effect with long-term continuous use, and how to avoid it?
- It promotes beneficial soil microbial activity and improves soil structure over time, without causing compaction or nutrient imbalance.
- Avoid excessive application—overdosing may lead to overly vigorous root growth but slower above-ground plant development.
- For saline-alkaline or heavy-metal contaminated soils, combine with soil testing and apply in split doses to prevent potential heavy-metal accumulation.
- Follow recommended dosage ranges (base + topdressing) for sustained soil and crop health.
2. What’s the difference between flakes and powder? How to choose?
- 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.
3. Can it be mixed with chemical fertilizers or pesticides?
4. How to adjust dosage for different soil types (saline-alkaline/sandy/clay)?
- Saline-alkaline soil: Increase dosage by 20-30% (base + topdressing) to enhance acid-adjusting and alkali-inhibiting effects;
- Sandy soil: Increase by 15-25% to maximize water-locking capacity;
- Clay soil: Reduce by 10-15% (avoids excessive moisture retention);
- Fertile soil: Reduce by 10-20% to prevent nutrient leaching.
5. How long does it take to see results after application?
- Soil improvement effects (loosening, water retention): Visible in 2-4 weeks (e.g., saline-alkaline soil EC value decreases by 15-20%);
- Crop growth effects (root development, vigor): 1-2 weeks for foliar spray/drip irrigation;
- Yield and quality improvement: Manifested in critical stages (flowering, fruit enlargement) or at harvest (yield +11.5-35%, sugar content +7-30%).
6. Is this product suitable for organic farming? What certifications does it have?
- 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.
7. What are the dilution ratios and operation key points for foliar spraying and drip irrigation?
- 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);
- Drip irrigation: Dilute 1:200-300 (w/v), stir thoroughly until fully dissolved, filter with 120-150 mesh screen to prevent nozzle clogging;
- Key note: Flakes need pre-soaking (10-15 mins) before dilution.
8. What are the storage conditions and shelf life?
9. What makes this product different from ordinary potassium humate?
- Higher humic acid content (65-70% vs. 50-60% for ordinary products);
- Large molecular weight (2-3x stronger water-locking and soil improvement effects);
- Strict organic certifications (CERES EU/NOP, REACH) for global market access;
- Proven results (11.5-35% yield increase in domestic field trials, applicable to problematic soils like saline-alkaline/sandy soil).
10. Are there any safety precautions during application?
- Avoid direct contact with crop roots (dig trenches/holes 15-20 cm away during topdressing) to prevent root burn;
- Wear gloves and a mask when operating, rinse with water immediately if it comes into contact with skin/eyes;
- Keep away from children and pets;
- Do not mix with strong acidic/alkaline substances (e.g., concentrated sulfuric acid-based fertilizers) to avoid flocculation.
