Ever since the fermentation of silage has been studied and discussed the question of the agent causing the fermentation has been ill controversy. Some investigators have made the statement, based on evidence more or less incomplete, that microorganisms are solely responsible for the changes undergone by the ensiled forage.

Still other writers have sometimes taken sides on the subject without presenting any new data bearing on the problem.
