ABSTRACT:
A method and apparatus for causing earthworms to come to the surface of soil in which electric pulses are applied to the soil. The pulses are characterized by high power during a brief burst followed by a relatively long rest period. The method requires a small power supply and may therefore be put into practice with portable equipment.
