How Fertilizer Made from Food Waste Can Help Drought-Stricken Farms

Our latest investment, California Safe Soils, has an innovative process for turning food waste into soil-enhancing liquid fertilizer

This California strawberry field is fertilized with H2H.

The U.S. industrial farming system has largely left natural fertilizers behind in favor of chemical-based fertilizers in the search for more efficiency and higher yields.
