Humic acid has been used in agriculture for decades, but most products are inconsistent in concentration and solubility. Here's how OA-Ag's FPT Humic Powder differs — and what it actually does in the soil.
Humic acid products have a reputation problem. Decades of inconsistent formulations — varying concentrations, poor solubility, and unverifiable source material — have made many growers skeptical. OA-Ag's FPT Humic Powder was formulated to solve those problems: concentrated, 100% water-soluble, and designed specifically for fertigation injection into drip and micro-irrigation systems.
In soil, humic acids bind to positively charged nutrient ions — calcium, magnesium, potassium — and hold them in forms that roots can access. This is cation exchange capacity at work. By improving CEC over time, FPT Humic makes every fertilizer dollar more efficient: nutrients you apply stay available longer instead of leaching past the root zone. Combined with the +30% carbon addition from OA-Ag's full product system, FPT Humic is the biological activation layer that makes everything else work better.
"The carbon-based program changed how our soil holds water. We're applying the same amount but seeing better uptake — the humic is doing exactly what it should." — Idaho Potato Grower, Potato Operations
FPT Humic is included in all three OA-Ag program tiers. Request a product spec sheet, or start with a free soil analysis to see what your current humic baseline looks like and where you have room to improve.
