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.

1. A method for treating an agricultural crop, the method comprising the steps of:providing a flow of substantially ozone-free water;generating an ozone-containing gaseous stream;forming a substantially continuously flowing ozonated water stream by introducing the gaseous stream into the flow of substantially ozone-free water, the forming step being conducted such that substantially no ozonated water is recirculated to the forming step; anddirectly applying the ozonated water stream to at least a portion of the agricultural crop;the steps of generating, forming and directly applying being performed by means of a transportable water processing system. 2. The method of claim 1 wherein the step of forming comprising introducing the ozone-containing gaseous stream into the flow of substantially ozone-free water no more than once, such that substantially no ozonated water is returned to the ozone-containing gaseous stream prior to the step of directly applying. 3. The method of claim 1 wherein the step of forming comprises forming an ozonated water stream having an ozone concentration of about 0.5 ppm to about 2.5 ppm. 4. The method of claim 3 wherein the step of forming comprises forming an ozonated water stream having an ozone concentration of about 1.0 ppm to about 2.5 ppm. 5. The method of claim 4 wherein the step of forming comprises forming an ozonated water stream having an ozone concentration of about 1.5 ppm to about 2.5 ppm. 6. The method of claim 1 wherein the agricultural crop is an agricultural crop that is generally less than about two feet in height above a ground level. 7. The method of claim 6 wherein the agricultural crop is an agricultural crop that is generally less than about 1 foot in height above a ground level. 8. The method of claim 1 wherein the agricultural crop is an agricultural crop selected from the group of agricultural crops consisting of leafy vegetable crops, cole crops, legume crops, annual fruit crops, and perennial fruit crops. 9. The method of claim 1 wherein the agricultural crop is a leafy vegetable crop. 10. The method of claim 9 wherein the leafy vegetable crop is a crop of lettuce plants. 11.
