RAW Humic Acid is a highly concentrated, water-soluble biostimulant derived from leonardite (59% humic acid). Rather than acting as a fertilizer, humic acid enhances nutrient efficiency by improving availability, buffering soil pH, and supporting root and microbial activity.
Humic acid builds the foundation for productive growth by improving how plants interact with nutrients and water at the root zone. It supports healthier soil structure, stronger roots, and more efficient fertilizer use, giving growers better results from the same inputs.
Key Benefits:
Nutrient Uptake Support: Humic acid binds minerals and increases their availability for absorption at the roots.
“Battery Effect”: As agronomist Harley Smith explains, humic (and fulvic) acids increase the voltage potential across plant cell membranes. This helps plants move essential trace elements like iron, manganese, and copper more effectively—improving nutrition and stress tolerance.
pH Buffering: Stabilizes acidic or alkaline soils, creating a more balanced root environment.
Proven Combination: Most effective when paired with RAW Kelp in the Virginia Tech–verified 5:2 humic-to-kelp ratio, shown to amplify nutrient uptake and microbial activity.
RAW Humic Acid is fully soluble and easy to integrate into soil, coco, or hydroponic systems.
