Introduction

For buyers, “humic acid” describes a family of humic substances used in soil and fertilizer formulations. The product name alone is not enough to compare suppliers: source material, form, analysis method, moisture, solubility and packaging should be confirmed against the shipment-specific specification.

What does humic acid do in a fertilizer program?

Humic acid is used as an organic soil-conditioning component. Depending on the formulation and application program, buyers may evaluate it for soil organic matter improvement, nutrient retention, water-retention support and root-zone management. These are application considerations, not a substitute for a crop-specific agronomic program.

FAQ

Is humic acid the same as fulvic acid?

No. They are related humic substances, but they are not interchangeable product names. Compare solubility, formulation and the specification requested for the application.

What is the source of Leiyuan’s humic acid?

Leiyuan is located in Shanxi, China, and identifies natural weathered coal or leonardite as the relevant source advantage. Confirm the exact grade and shipment specification before ordering.

Which documents can a buyer request?

Ask for the agreed technical specification and shipment-specific COA. MSDS and export documents can be discussed according to the destination and shipment requirements.
