N-Ext Humic12 Liquid Humic Acid 0-0-1

High-Concentration Liquid Humic Acid for Soil Health and Nutrient Efficiency

N-Ext Humic12 delivers 12% humic acid, a concentration significantly higher than most DIY-available options. Humic acid is a fundamental driver of soil fertility, and Humic12 is the direct way to elevate it. The benefits are measurable across multiple dimensions of turf health: improved root mass, increased chlorophyll production, better nutrient uptake, enhanced soil structure, improved water retention, and more efficient mineral chelation.

Humic12 is part of the N-Ext Bio-Stimulant Package alongside RGS, Air-8, and MicroGreene, and is a core component of the RGS/Humic12 combo that builds root strength and soil carbon simultaneously. One gallon treats up to 21,300 square feet.
