Humuson 400

Humuson 400 is the concentrated version of our sapropel-based liquid fertilizer, formulated to deliver a higher dose of humic and fulvic acids per application than Humuson 200. It's built for operations that need to treat larger areas efficiently without sacrificing the soil-biology benefits that make the Humuson line effective.

How It Works
The same humic and fulvic acid complexes found in Humuson 200 are present here at a higher concentration, allowing growers to cover more ground per gallon while still feeding soil microbiology, improving nutrient cycling, and increasing the soil's water-holding capacity.

Who It's For
Humuson 400 is designed for larger-scale agricultural operations, commercial growers, and any application where maximum efficiency per gallon matters — whether that's reducing application frequency or covering more acreage with the same volume of product.

Key Benefits
- Higher concentration of humic and fulvic acids per application
- Reduces application frequency on larger operations
- Improves nutrient uptake and soil water retention
- Supports long-term soil restoration and microbial health
- Compatible with organic and regenerative growing practices
