The Science of RainGrow

Humic substances are natural compounds that are present in most fertile soils. These substances have been identified as having the most positive effects on soil properties. Benefits include but are not limited to an increase in water and nutrient holding capacity, aeration, and support for microorganisms.

Using our comprehensive understanding of the physical, chemical, and biological properties of humic substances, RainGrow has developed an innovative technology that separates these organic compounds into the fractions of our choosing. This revolutionary process affords us the luxury of selecting fractions based on their distinctive attributes, many of which are ideally suited for environmental bioremediation and the restoration of soil health.

The fundamentals of this patented process are performed at the molecular level. In the current industry, the extraction of humic substances, specifically fulvic acid, is achieved using harsh chemicals in a base-acid reaction. This process is both costly and introduces high levels of contaminants as a consequence of the chemical process itself. By comparison, our physical separation method removes the need for residue-adding extractants thereby producing exceedingly pure, concentrated and environmentally friendly products.

Fractions which we are proficient at isolating and collecting include humin, humic acid, and low molecular weight humic substances (LMWHS), or simply light humics (LH). These fractions represent our Remediation Products. The use of LH plays an important role in our bioremediation methodology. This fraction is the most biologically active fraction of humic substances and includes the more commonly known fulvic acid.

By using our innovative process in the separation of humic substances, we are able to select fractions for their specific uses in bioremediation and site rehabilitation. This practice ultimately reduces both costs and the time to project completion.
