▶️ Case 1: Smallholder Strawberry Yield Enhancement
- Application: JFHA-HA-1 Powder (450 kg/ha) mixed with sheep manure (1:3) as base fertilizer.
- Results: Yield increased by 18%, fruit sugar content rose from 16% to 19%, and soil organic matter reached 2.2% (1 growing season).
- Key Driver: Fine particle size ensured uniform distribution in manually applied fields, accelerating nutrient activation.
▶️ Case 2: Seedling Substrate Improvement for Vegetable Nurseries
- Application: 8% (volume) JFHA-HA-1 Powder added to seedling substrate.
- Results: Seedling survival rate improved by 32%, root dry weight increased by 25%, and transplant shock was reduced significantly.
- Key Driver: High CEC (≥200 meq/100g) stabilized substrate pH and retained moisture for young roots.
▶️ Case 3: Saline-Alkaline Soil Remediation for Orchards
- Application: JFHA-HA-2 Powder (1,500 kg/ha) broadcast along drip lines, mixed with 750 kg/ha gypsum.
- Results: Soil pH dropped from 8.2 to 7.3 in 6 months, organic matter increased from 1.2% to 1.8%, and tree vigor improved by 28%.
- Key Driver: Organic matter (80% min) and humic acid (50% min) promoted salt leaching and soil aggregate formation.
▶️ Case 4: Organic Fertilizer Enhancement for Compost Blends
- Application: 10% (weight) JFHA-HA-1 Powder mixed with chicken manure compost.
- Results: Blended fertilizer’s organic matter content increased from 45% to 52%, organic carbon from 26% to 30%, meeting high-standard organic farming requirements.
- Key Driver: High-purity humic acid (60% min) directly boosted organic carbon and matter without diluting nutrient density.
💬1. What makes your insoluble humic acid powder stand out from competitors?
✅Our powder features a precise 80-100 mesh fineness (95% pass rate) for maximum soil contact, high humic acid content (50-60% dry basis), and strict heavy metal limits (compliant with AAPFCO/ISO standards). It’s cost-effective for smallholders and delivers faster results (1-2 weeks) than coarser alternatives.
💬2. Can I use this powder for foliar spraying or hydroponics?
✅No. It is 100% water-insoluble and designed exclusively for soil application (including seedling substrates and fertilizer blending). For foliar use, please explore our soluble humic acid product line.
💬3. How flexible is the mixing ratio with organic/NPK fertilizers?
✅The recommended 1:3 ratio (powder:organic fertilizer) is optimal, but it can be adjusted between 1:2 to 1:4 based on soil fertility. When blending with NPK, mix 5-10% powder by weight of chemical fertilizer to enhance nutrient retention.
💬4. Is the powder suitable for all soil types, including acidic soils?
✅Yes. While it excels in saline-alkaline/neutral soils (pH 6.0-8.5), it also benefits acidic soils (pH 4.0-6.0) by improving soil structure and nutrient availability. For acidic soils, reduce dosage by 10-15% and monitor pH after application.
💬5. How should I store the powder to maintain quality?
✅Store in sealed, moisture-proof woven bags (with inner PE film) in a cool, dry warehouse (temperature 5-30℃). Avoid direct sunlight, acidic substances, and high humidity. Clumping due to dampness is normal—crush before use to restore efficacy.
💬6. Does this product qualify for organic farming certification?
✅Yes. It is derived from 100% natural weathered coal/lignite, free of synthetic additives, and compliant with USDA Organic, EU Organic, and China Organic Agriculture standards. We provide certification documents upon request.
💬7. Can I use this powder to enhance homemade compost?
✅Absolutely. Add 5-10% powder by weight to compost piles during the thermophilic stage. It accelerates decomposition, increases organic matter/carbon content, and reduces nutrient loss (e.g., nitrogen volatilization).
💬8. What is the difference between JFHA-HA-1 and JFHA-HA-2 Powder?
✅JFHA-HA-1 has higher purity (85% min organic matter, 60% min humic acid) for high-value crops/soil remediation. JFHA-HA-2 (80% min organic matter, 50% min humic acid) is a cost-effective option for general farming and fertilizer blending.
💬9. Do you provide third-party test reports for international trade?
✅Yes. We offer test reports compliant with AAPFCO, ISO 19822, and GB/T 11957-2001 standards, covering humic acid content, heavy metals, CEC, and particle size. Reports are issued by SGS, Intertek, or CTI upon order.
💬10. How long does the powder’s effect last in soil?
✅The primary effect lasts 1-2 growing seasons (6-12 months) for soil structure improvement. For long-term benefits, apply annually at 50% of the initial dosage to maintain organic matter levels and soil health.
BENEFITS
- 80-100 mesh fineness: Maximizes soil contact for fast (1-2 week) structure improvement.
- Budget-friendly: Lower unit price, perfect for manual smallholder application.
- Fast nutrient release: Ideal for short-cycle crops (strawberries, broccoli) needing quick vigor boosts.
- Versatile mixing: Easily blends with fertilizers/substrates (1:3 with organics; 5-10% in seedling mixes).
- Low-dust, moisture-proof packaging for easy storage.
