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.
