Abstract: A water processing system is provided for providing plasma-catalytic enhanced water that contributes to improved yield and growth of plants. The system may include a plasma power supply configured to initiate the plasma and regulate the plasma discharge current of a plasma discharge, a plasma discharge reactor connected to the plasma power supply and configured to generate the plasma discharge, a pump connected to a water source and configured to deliver water to a nozzle configured to spray water into the plasma discharge, a compressor connected to a gas source and configured to deliver a gas for the plasma discharge, and collector to collect the water after the water has passed through the plasma discharge. Methods of making and applying the plasma-catalytic enhanced water are also provided.
