HGS BioScience Expands Capabilities with Two Strategic Acquisitions
Earthgreen and Menefee Mining Assets Strengthen Product Development
HGS BioScience, a global provider of extracted humates in granule and liquid forms, has announced the acquisition of Earthgreen Products, Inc. and Menefee Mining Corporation, two companies recognized for their contributions to soil health and plant productivity. The acquisitions will allow HGS BioScience to offer an expanded range of humic and fulvic acid products, leveraging raw material quality and advanced formulation technologies.
The addition of the Menefee mine in New Mexico provides access to high-grade freshwater humates, which are known for their elevated levels of humic and fulvic acids and are widely regarded for their biological activity and consistency.
“Humates mined from New Mexico’s Menefee Formation are known to be among the world’s highest quality natural humate deposits,” said Mike Steffeck, CEO of HGS BioScience.
HGS BioScience’s Enhanced Portfolio with Flexible Formulations
Granules, Liquids, and Powders to Meet Grower Needs
Following the acquisitions, HGS BioScience now offers one of the industry’s most comprehensive portfolios of extracted humate products, including patented granules, powders, and liquids. A flagship product in the lineup is HumiK ONE, a humic acid granule that delivers the power of a liquid formulation in a dry form, compatible with nutrients, biologicals, and biostimulants.
The updated portfolio also includes:
- Low-use rate products
- Mixable dry formulations for liquid blending
- A full line of humic and fulvic acid-based liquids
These products are designed to rapidly solubilize, integrate easily with fertilizer systems, and support soil structure improvement and nutrient use efficiency.
