Frequently Asked Questions
What is the raw material source of this Humic Acid?
Our Humic Acid is derived from 100% natural, high-grade Leonardite, ensuring maximum biological activity and premium quality for agricultural applications.
How does Humic Acid improve soil water retention?
Humic Acid acts as a natural soil structure improver by promoting aggregate formation, which increases the soil's water holding capacity and reduces moisture evaporation.
Can this product be used with other chemical fertilizers?
Yes. Humic Acid enhances nutrient availability and reduces chemical inputs by chelating essential minerals, preventing nutrient leaching, and making them more accessible to plant roots.
What are the differences between the three specification options?
The options vary primarily by their Potassium (K2O) content, ranging from 5% to 12%, allowing you to select the optimal formulation based on your specific crop requirements and soil conditions.
What is the standard packaging and MOQ for orders?
Our Minimum Order Quantity (MOQ) starts at 1*20GP container (approx. 13 tons). We also support larger shipments of 1*40GP containers (approx. 18 tons) to meet commercial farming needs.
