Description
NPK RAW Humic Acid is a highly concentrated biostimulant containing 59% humic acid derived from leonardite, making it one of the most water-soluble sources on the market.
Humic acid binds minerals and increases their availability for root absorption, stabilizes pH in acidic or alkaline conditions, and enhances cation exchange capacity to stimulate beneficial microbes and promote robust root systems.
It increases the voltage potential across plant cell membranes, helping plants move essential trace elements like iron, manganese, and copper more effectively.
Most effective when paired with RAW Kelp at a 5:2 humic-to-kelp ratio.
