Fermented Food Waste Can Benefit Crop Growth

Scientists at the University of California, Riverside, discovered that adding fermented food waste to growing systems can increase beneficial microbes that increase plant growth and make plants more resistant to pathogens. The scientists tested both the beer mash byproduct and mixed food waste from grocery stores and found that fermenting either waste and adding it to water that was used on plants caused the beneficial microbes in the system to increase two- to three-fold within a day. The scientists say the practice could reduce carbon emissions and reduce or replace synthetic chemical inputs, saving farmers money.
