Leonardite-derived potassium humate for soil structure and nutrient uptake. Ferti-Organic Soluble Humic Acid 0-0-7 is an OMRI Listed potassium humate derived from leonardite mineraloid with a minimum 60% humic content including fulvic acids. It improves soil aggregation, cation exchange capacity, microbial activity, and nutrient availability — delivering 7% soluble potash as a bonus nutrient input.

Optimized for Soil Biology and Structure

Humic acid from leonardite provides a concentrated source of biologically active carbon that feeds soil microbes, improves water retention, and enhances the availability of phosphorus and micronutrients. The soluble formulation allows precise application via fertigation or foliar spray.
