ABSTRACT:
A method of root fertilization in cultivated plants, particularly in the field of hydrophonics is provided wherein water is finely impregnated with a gas mixture of carbon dioxide and pure oxygen, whereby the mixing ratio of the carbon dioxide and the pure oxygen corresponds approximately to the natural solution ratio of carbon dioxide and oxygen in normally clean water at atmospheric pressure and room temperature and whereby the individual gaseous phases, respectively their inflow to the gas mixture, can be controlled when required from the gas mixing area.
