PLANT YIELD INCREASING METHOD Russian patent published in 2003 - IPC

FIELD: agriculture. SUBSTANCE: method involves creating potential difference not in the excess of 15 V per running meter of soil surface. Potential difference is created by watering plants with colloidal solution charged with negative charge particles, with watering being performed at least in each 1-3 days. Colloidal solution is, for example, rosin colloidal solution. Method enhances natural plant growth promoting process by creating and regulating homogeneous soil electric fields with relatively constant current density value over the entire volume. Method allows plants to be cultivated in open ground as well as in greenhouses. EFFECT: increased yield and simplified method. 2 cl
