Considerable is known concerning the immediate effect on root growth of excess carbon dioxide and shortage of oxygen in the soil. The ecologic importance of soil atmosphere in relation to root growth has also been studied. Very little work has been done on the formative and metabolic effects of continuous liberal soil aeration on plants so grown. A preliminary report is herewith presented of the formative effects of optimal air supply upon root and top growth in several types of plants whose roots differ in their oxygen requirements.
