Humic Acid Flakes – Standard Grade (K₂O 8–10%)
Reliable Humic Source for Soil Conditioning, Root Growth & Better Nutrient Uptake
Standard Humic Acid Flakes (K₂O 8–10%) are made from naturally oxidized leonardite through alkaline extraction.
This grade provides excellent soil-conditioning benefits, improves nutrient absorption, and enhances microbial activity at an economical cost.
Ideal for soil application, drip irrigation, basal application, and use in organic blends.
🌱 Key Benefits
Improves Soil Structure
• Enhances aeration, water retention & reduces compaction.
Promotes Root Growth
• Supports deeper, stronger roots for efficient nutrient uptake.
Enhances Nutrient Availability
• Natural chelating action improves NPK + micronutrient absorption.
Boosts Fertilizer Efficiency
• Minimizes nutrient leaching & volatilization losses.
Supports Microbial Activity
• Provides carbon source for beneficial soil microbes.
Improves Stress Tolerance
• Helps crops withstand drought, salinity & temperature variations.
Better Yield & Crop Quality
• Supports uniform growth & healthy plant development.
💧 Application & Dosage Table
| Application Method | Dose | Purpose / Benefit |
|---|---|---|
| Soil Application (Basal) | 1–2 kg/acre | Improves soil carbon & long-term soil health |
| Drip Irrigation / Fertigation | 500–750 g/acre | Enhances root activity & nutrient transport |
| Foliar Spray | 1–2 g/L | Quick nutrient chelation & stress recovery |
| Seed Treatment | 4–6 g/kg seed | Better germination & strong root initiation |
| Root Drench / Nursery | 1–2 g/L | Boosts early seedling vigor |
