An ozone system for agricultural applications generally includes a water flow line having an inlet for receiving a flow of clean water from a water source, an ozone injector suitable for producing a high concentration of ozone in oxygen, and a venturi injector for injecting the ozone gas into the water flowing through the flow line to produce an ozonated water stream. In addition, the system includes a degassing assembly for separating and removing undissolved ozone gas from the ozonated water stream and an ozone destruct assembly adapted to destroy the undissolved ozone. The entire system is motorized vehicle mountable to provide ease in applying the ozonated water stream from the system to agricultural crops.
