Insoluble Humic Acid Round Granule Prill. Humic acid is formed by microbial degradation of dead biological substances, extracted from leonardite. It consists of humic acid (HA), fulvic acid (FA), and humin (HM). Our variations include 15%/50%/60% humic acid with NPK 14-0-1.
✅ Usage: Ideal as basal fertilizer or topdressing. It improves carbon sources in soil and enhances microbial populations. Suitable for field crops, organic farming, horticultural plants, landscape, and lawns.
✅ Nutrient Profile: Contains more than 12 kinds of nutrients including NPK, Organic Matter, Potassium, and Trace Elements (Ca, Mg, S, Zn, Fe, Cu).


1. Low moisture and dust; high free humic acid and organic matter.
2. Slow Release effect improves NPK utilization rates.
3. Increases Nitrogen utilization by 15% to 20%.
4. Enhances soil water holding capacity and remediation for sandy or salt-affected soils.
