Humic Acid Fertiliser (Potassium Humate)
HS3824.99.96Standard
Humic Acid Fertilisers derived from leonardite and lignite improve soil structure, enhance nutrient use efficiency, stimulate root development, and increase microbial activity. SFERA LLC supplies potassium humate in powder, flake, and granule forms with guaranteed humic acid content of ≥70% (dry basis) and fulvic acid of ≥15%. Russian leonardite deposits — particularly in Siberia and the Urals — are among the world's richest sources of high-quality humified organic matter. These products are widely adopted in precision and regenerative agriculture, fertigation systems, and organic-certified programmes. Full laboratory analysis confirms humic acid, fulvic acid, K₂O, pH, moisture, and solubility on every batch.
