Increasing Productivity with solar cell-powered electrokinetic treatment

Abstract

In this study, an electrokinetic method using a 6 V solar cell was applied to saturated black soil mixed with cow manure compost (compost-mixing ratio was 47%), and a cultivation test of Japanese mustard spinach was conducted to confirm changes in productivity due to the application. As a result, the effect of oxidation reaction at the anode on the plant growth was extremely low. On the other hand, it was found out that the reduction reaction at the cathode significantly affected the plant growth. Specifically, the productivity in the soil within 40 cm from the anode was increased. In addition, the productivity in the soil around 20 cm from the cathode was affected by the reduction reaction. In the future, it is necessary to verify the effect of this technology under field conditions (drainage irrigation).
