Humic Land™ Case Studies Results

What Is Humic Land™ ?

Increases Yields | Improves Nitrogen Uptake | Reduces Watering Costs

Humic Land™ is an organic soil amendment that increases your soil's ability to cycle nutrients to relieve your fertilizer dependence.

Unlike other Humic Acids available on the market that originate from Lignite or Leonardite, Humic Land™ comes from Black Peat.  A vital disctinction, as not all Humic Acids are made equal. Humic Land™ is made from peat, using cavitation and fine grinding without any chemicals used in the production process.

The resulting product is a peat gel that is 100% Organic which restores soil health and prevents Nitrogen Leaching.

Rebuild your soil with Humic Land™ directly at the rhizosphere where it matters most by improving nitrogen retention. When nutrients are readily available as your crops needs them... yields increase.
