Abstract
The invention provides a method of supplying dissolved carbon dioxide to plants in an aqueous medium characterized by electrolyzing the water in the aqueous medium by electrodes disposed in the aqueous medium and supplied with electric current. At least one of the electrodes is a carbon electrode which acts as a positive electrode. The current density is supplied to the electrodes at or below the level at which no, or substantially no, gaseous oxygen is formed at the positive carbon electrode.
