The Science Behind Humic Acid Powder

This humate powder is extracted from Leonardite, a natural deposit formed over millions of years, far more concentrated and stable than peat-based sources. Rich in short- and medium-chain humic acids, it acts as a bio-stimulant, soil detoxifier, and chelator.

• Nutrient Chelation – Unlocks bound-up nutrients like phosphorus, calcium, and magnesium
• Soil Detox – Binds herbicide/pesticide residues, heavy metals, and excess salts
• Microbial Support – Provides carbon and substrate for beneficial bacteria and fungi
• Water Retention – Improves soil porosity and reduces evaporation
• pH Buffering – Helps stabilise soil pH in both acidic and alkaline soils
• Structure Repair – Encourages soil crumb formation and reduces compaction
