▶️Case 1: Fertilizer Blending Production (Henan, China)
- Background: A fertilizer manufacturer needed a functional additive to upgrade compound fertilizer with soil improvement benefits.
- Application: Added this prill at 8% ratio during compound fertilizer spray granulation (no production line modification).
- Results: Blended fertilizer sales increased by 22% (core selling point: «soil-friendly + nutrient retention»); farm trials showed soil CEC improved by 32%, and fertilizer utilization rate rose by 18%.
▶️Case 2: Corn Mechanical Fertilization (Heilongjiang, China)
- Background: 600-acre corn field with sandy loam soil (poor nutrient retention); required dust-free, mechanized soil amendment.
- Application: Applied 1000 kg/ha via fertilizer spreader (integrated with seeding machine).
- Results: Corn yield reached 8.5 tons/ha (+16% vs. control group); mechanical application reduced labor costs by 70%, transportation loss was only 0.7%.
▶️Case 3: Apple Orchard Soil Improvement (Shandong, China)
- Background: 12-year-old orchard with soil compaction (bulk density 1.48g/cm³) and declining fruit quality.
- Application: 0.8kg per tree (furrow application) in autumn, blended with organic fertilizer.
- Results: Soil bulk density decreased to 1.15g/cm³; fruit soluble solid content increased by 17%, and chemical fertilizer usage reduced by 20%.
▶️Case 4: Saline-Alkaline Soil Remediation (Inner Mongolia, China)
- Background: Rice field with severe salinization (pH 8.8, organic matter <1.2%); traditional yield <300kg/mu.
- Application: Applied 1200 kg/ha as base fertilizer (mechanical broadcasting), plowed into 25cm soil.
- Results: Rice yield reached 630kg/mu (+110% vs. control); soil pH dropped to 7.4, organic matter increased to 2.6%.
💬Q1: What’s this product’s core market differentiation vs. competitors?
✅Unlike loose granules/powders (high moisture/caking risk), our spray-granulated prill (≤10% moisture, ≥20kgf hardness) is purpose-built for fertilizer blending—this unique positioning lets clients avoid post-production quality issues, a key pain point in the fertilizer market.
💬Q2: How does the 40-50% humic acid content support market positioning?
✅This range is above the 30-35% industry average for insoluble humic acid products, enabling clients to position their blended fertilizers as «high-content soil-improving formulas»—a strong selling point for mid-to-high-end agricultural markets.
💬Q3: Which equipment does the INSOLUBLE HUMIC ACID PRILLS fit? Can it cut our market service costs?
✅It’s compatible with mainstream fertilizer granulators, spreaders, and seeding machines (no special equipment required). This eliminates the need for custom equipment guidance, reducing your after-sales service costs by ~15%.
💬Q4: Which brands have adopted this product? What’s the market feedback?
✅3 regional fertilizer brands (e.g., Henan Xinyuan Fertilizer) have launched products with this prill; their feedback includes: «no caking complaints» and «15-20% sales growth in target segments»—we can share detailed case materials for your marketing.
💬Q5: How much market premium can this insoluble humic aid prills bring to my fertilizer products?
✅Clients typically price blended fertilizers 10-15% higher than standard products (backed by the «45% humic acid + soil improvement» claim); in premium orchard markets, this premium can reach 20%.
💬Q6: What’s the supply lead time? Can it support peak-season market demand?
✅ Lead time is 7-10 days for bulk orders (100+ tons); we maintain 500-ton safety stock during peak seasons (March-June) to ensure you meet market order deadlines.
💬7. Does this product support custom packaging? Can it match our brand marketing?
✅Yes—we offer custom packaging (logo, product claims, design) to align with your brand identity. This helps maintain consistent market branding for your fertilizer lines.
💬Q8: How much marketing cost can we save vs. using humic acid powder?
✅Powder products require dust-proof packaging and additional dispersants (cost +10%); our prill eliminates these expenses, and its low-loss feature reduces sample/wastage costs for market promotions.
💬Q9: Is this product accepted in overseas markets? Are there relevant certifications?
✅It’s certified by CERES and meets EU 2019/1009 standards, so it’s widely accepted in European, North American, and Southeast Asian organic agricultural markets—we can provide certification documents for your export marketing.
💬Q10: What channel support policies do you offer for bulk buyers?
✅We provide free samples (for client market testing), customized product brochures (for your sales teams), and joint marketing case studies (to support your client acquisition efforts).
BENEFITS
- Low Moisture & Anti-Caking: Moisture content ≤10% (spray granulation advantage), ensuring compatibility with fertilizer production lines.
- High Hardness for Blending & Mechanization: Dense, hard granules (≥3kgf) resist breakage during mechanical mixing/transportation, ideal for fertilizer blending (5-15% addition ratio) and large-scale mechanical fertilization.
- Long-Lasting Soil Improvement: Insoluble humic acid releases gradually via microbial degradation (3-6 months), boosting soil CEC (≥180meq/100g), promoting aggregate structure, and reducing soil compaction/salinization.
- Enhanced Fertilizer Efficiency: Binds with nutrient ions (N/P/K) to reduce leaching loss, improving fertilizer utilization rate by 15-20% when blended with chemical/organic fertilizers.
- Eco-Friendly & Low Loss: Dust-free during application (protects operators/equipment), transportation loss ≤1% (vs. 5-8% for powder), aligning with green agricultural standards.
