Research shows the
benefits of humic materials

Our goal is to help educate our partners on the most recent innovations in humic acid technology and the benefits of adding humic to your soil health program.

Our Resource

Our deposit of humalite – a weathered type of sub-bituminous coal found only in Alberta and used exclusively for Black Earth Products. Black Earth humics are guaranteed to contain at least 80% humic acid (Colorometric), many of which are certified organic.

High in humic and fulvic acids yet low in ash and toxic metals, our humalite is superior to lignite and leonardite. By harnessing its chemical and physical potential we develop innovative, highly effective products for a wide range of applications in the agricultural, environmental and industrial sectors.

Testing Method

All humiZen products use the “HPTA” testing method to report humic & fulvic acid content. Most suppliers report content using a simple analysis called the “colorimetric” method. This method shows a higher result but is less accurate and is easily deceived by non-humic additives. We hold the humiZen brand to the highest standards and have chosen the highest standard of analysis.

Applied Research

A significant amount of research has been completed to substantiate various claims of the use of humus materials.

Our company has completed numerous projects with major institutions and companies, such as Agriculture Canada, Alberta Agriculture, Alberta Research Council, Guelph Turf Grass Institute, University of Saskatchewan, University of Manitoba, Dalhousie University and National Water Research Institute. Dr. Morris Schnitzer, a notable world class scientist in humic substances, was involved in several of our projects. Together with results obtained by others, research shows the many benefits of humic substances contained in humus materials:

  • They improve soil texture and water retention.
  • Humic substances are similar to auxin growth hormone, improving living cell metabolism / growth.
  • They perform similarly to chelating agents and surfactants.
  • Humic substances provide available carbon to microorganism.
  • Humic substances are generally safe to the environment and all living organisms.
