Understanding and Improving Fermentation in Alfalfa and Grass Baleage

The ancient Egyptian and Carthaginians are believed to be the first conserve forage by ensiling it in the absence of oxygen. Though the technique has been refined in the 3500 years since, the basic fermentation process has not changed. Populations of naturally-occurring bacteria on the plant surface can consume some of the readily available carbohydrates and produce organic acids. These organic acids lower the pH of the forage material and prevent fungal deterioration of the product. Fermentation has been used for millennia as a natural method for preserving food. Similar bacterial fermentation occurs when one makes yogurt, sour cream, or pickles
