Before you head to the fields to harvest alfalfa or corn silage, take some time to clean your forage wagons, as well as upright silos and bunkers in which you store your forages.

“Silos and forage wagons should be cleaned before filling,” says Limin Kung, professor of ruminant nutrition and microbiology at the University of Delaware. Likewise, remove moldy and spoiled silage from your bunkers or upright silos so that they don’t contaminate fresh forage.
