HUMIC ACIDS- ▸ Agriculture: Soil amendment raising cation-exchange and water-holding capacity
- ▸ Drilling fluids: Fluid-loss-control and deflocculating additive for water-based muds
- ▸ Water treatment: Sorbent for metals and organics
- ▸ Foundry: Additive in green-sand systems
A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Humic acid (CAS 1415-93-6) is a UVCB humic substance typically derived from leonardite or lignite. It is used as an agricultural soil amendment that raises cation-exchange and water-holding capacity, as a fluid-loss-control and deflocculating additive in water-based drilling muds, and as a sorbent in water treatment.
Frequently Asked Questions
What is humic acid used for?
Humic acid (CAS 1415-93-6) is a UVCB humic substance typically derived from leonardite or lignite. It is used as an agricultural soil amendment that raises cation-exchange and water-holding capacity, as a fluid-loss-control and deflocculating additive in water-based drilling muds, as a sorbent in water treatment, and as an additive in foundry green-sand systems.
What does humic acid do in soil?
As a soil amendment it raises cation-exchange capacity and water-holding capacity, improving nutrient retention and soil structure. It is applied as a conditioning input rather than a direct nutrient source.
What is humic acid made from?
Industrial humic acid is typically extracted from leonardite or lignite — oxidized, low-grade coal sources rich in humic substances. As a UVCB material its exact composition varies with feedstock and processing.
What grades or forms of humic acid does RawSource supply?
Humic acid is supplied in bulk for agricultural, drilling-fluid, and water-treatment use; form and active content vary by source. Specify your application and required active percentage when requesting a quote, and a CoA will confirm the lot specification.
What bulk packaging and MOQ apply to humic acid?
RawSource supplies humic acid in bulk bags, drums, or totes depending on form. MOQ, lead time, and pricing are quote-based — request a bulk quote with your target volume and an SDS and CoA accompany the order.
