Humic Acid Soluble Powder – 60% Humic Acid + Naturally Occurring Fulvic Acid
Soil Conditioner • Nutrient Uptake Enhancer • Microbial Activator
Our Humic Acid Soluble Powder is a highly concentrated product containing 100% soluble humic acids, designed for easy mixing into water for soil drenches and foliar sprays.
Rich in both humic and fulvic acids, this powerful amendment improves nutrient availability, stimulates beneficial microbes, enhances soil structure, and supports healthier, more resilient plants—naturally. Perfect for regenerative agriculture and living soil systems focused on long-term soil health.
Key Benefits
🧲 Maximizes Nutrient Uptake
Helps chelate nutrients and improve their availability for plant uptake, increasing nutrient-use efficiency and reducing losses.
🌱 Boosts Soil Microbial Activity
Provides organic carbon and supports the biological activity responsible for nutrient cycling and soil vitality.
💧 Improves Water Retention
Increases the soil’s ability to hold water and nutrients, reducing leaching and supporting drought resistance.
🌾 Enhances Soil Structure & Aeration
Improves cation exchange capacity (CEC), soil porosity, and root development for healthier, more productive plants.
⚖️ Balances Nutrient Availability
Its high cation exchange capacity helps retain nutrients and buffer changes in soil chemistry, supporting more consistent nutrient availability.
🌿 Improves Germination & Rooting
When used at an appropriate rate, humic and fulvic acids can support seed germination, early root development and transplant establishment.
🔬 Contains Humic + Fulvic Acids
Humic acid supports soil structure, nutrient retention and cation exchange capacity, while the smaller, more mobile fulvic acid fraction helps complex micronutrients and supports their availability to plants.

Product Analysis
-
Soluble Potash (K₂O): 15.0%
-
Humic Acid: 60% — tested using ISO 19822
- Hydrophobic Fulvic Acid: 5.65% in representative ISO 19822 testing
The humic acid content is based on the product specification. The fulvic acid result is from representative testing of the naturally occurring mineral source and may vary slightly between production lots.
📖 Testing Method
Humic and fulvic acid content is measured using ISO 19822, an internationally recognized and HPTA-approved testing method developed specifically for humic-based fertilizers and soil amendments. This standardized analysis provides reliable measurements of both humic acid and hydrophobic fulvic acid, helping ensure accurate, transparent content claims.
