USDA agricultural research service scientists have found that dried distiller’s grains (DDGs) have potential as organic fertilizer and for weed control. If this idea takes off, it may impact future DDG price and availability in some areas.
In greenhouse and field studies, researchers found that DDG-treated plots of Roma tomatoes yielded 226 total pounds of fruit, versus 149 pounds from untreated plants. And in turfgrass trials, the DDGs stopped annual bluegrass and other weed seeds from germinating in stands of Kentucky bluegrass.
However, more ethanol plants are using dry-grinding methods, so research is under way to determine how that impacts DDG biochemical and physical properties. And whether that shift in methodology changes the potential uses of DDGs.
