Abstract: An apparatus, method and system for eradicating soil-borne pests in soil utilizing leading and trailing rows of shanks, a source of electricity and a mechanism to determine the condition of the soil being treated. The leading row has ripper shanks that open a path through the soil and the trailing row has specially configured electrically conductive stinger shanks, connected to the source of electricity, that discharge electricity into the soil to electrocute pests. The soil condition determination mechanism comprises one or more soil probes in a probe row disposed between the leading and trailing rows. The soil probe reads the condition of the soil in the path cut by the ripper shanks and transmits a signal to a voltage controller that is connected to the source of electricity to adjust the output thereof to the stinger shanks to automatically compensate for changing soil conditions to effectively and efficiently eradicate pests.
