(Specification Grades: 40%, 50%, 65%, 70%) Origin: Premium Xinjiang Lignite

NO.1: Key Advantages

Lignite Humic Acid Powder delivers transformative benefits through advanced technology:

1. High-Activity Extraction
   Utilizing Xinjiang lignite, our alkaline activation and thermal reaction process achieves 82.19% extraction efficiency. The uniformly distributed molecular structure features abundant carboxyl/phenolic groups, enhancing NPK utilization by over 20%.

2. Comprehensive Soil Reformation
   Significantly improves soil aggregation (10-20% water-stable clusters), reduces salinity pH, and traps heavy metals (Pb, Cd). Additionally, it boosts water retention capacity by 500-600%.

3. Plant Growth Synergy
   Stimulates root systems (30% more fibrous roots) while building environmental resilience. Crucially, it enhances photosynthesis and fruit expansion during critical growth stages.

4. Eco-Conscious Production
   Sourced from natural lignite and manufactured pollution-free, Lignite Humic Acid Powder meets NY 1106-2010 agricultural standards for sustainable farming.

NO.3: Application Guidelines

Maximize Lignite Humic Acid Powder‘s effectiveness with these methods:

1. Application Methods

   • Base Application: Blend with organic/compound fertilizers (30-75kg/ha; halve for high-concentration grades).

   • Fertigation: Dilute 200-500x; apply every 10-15 days during growth cycles.

2. Critical Timing
   For optimal results, apply during transplant recovery, bud differentiation, fruit swelling, and color-change phases alongside NPK fertilizers.

3. Dosage Reference
   Field crops: 15-45kg/ha • Fruit trees: 45-75kg/ha • Greenhouse vegetables: 30-460kg/ha

NO.4: Important Precautions

1. Temperature Sensitivity
   Apply at 18-35°C; effectiveness may decrease above 38°C.

2. Compatibility Notes
   Pre-test mixtures with strong acids or Ca/Mg fertilizers to prevent precipitation.

3. Storage Protocol
   Store sealed in darkness (2-year shelf life). Temporary clumping post-opening doesn’t affect performance.

NO.5: Production Excellence

Lignite Humic Acid Powder undergoes rigorous processing:

1. Raw material grinding (200-300 mesh; ≤7% moisture)

2. Alkaline activation (0.94mol/L NaOH, 65°C, 82min)

3. pH neutralization (NH₄OH to pH 7-9)

4. Nutrient fortification & granulation

NO.6: Technical Insights

1. Understanding Humic Acids
   Naturally occurring macromolecules from decomposed lignite with carboxyl/phenolic groups that enhance soil structure and plant vitality.

2. Stability & Shelf Life
   Retains potency for 3 years when sealed. Note: Clumping from humidity doesn’t degrade quality.

3. Fulvic vs. Humic Acids
   Fulvic acid (humic subset) has lower molecular weight (<1000 Da) and superior solubility for direct plant uptake.

4. Fertilizer Synergy
   Combine with 10-20% reduced chemical fertilizers; Lignite Humic Acid Powder minimizes nitrogen loss and phosphorus fixation.

5. Soil Regeneration
   Proven to form soil aggregates, sequester pollutants, balance pH, and feed microbes – increasing yields by 10-30% in degraded soils.
