Abstract
A system for agricultural irrigation water oxygenation for enriching soil oxygen level comprises a source of compressed oxygen (and not compressed air) coupled to a water line feeding an irrigation system, such as a drip irrigation system. The coupling system may include a pressure sensor for measuring the pressure in the water line, a solenoid safety valve, a control valve, a flow meter and a controller that controls the flow of oxygen from the source of compressed liquid oxygen to the water line using the components of the coupling system, without using a special cavitation valve and using off-the-shelf components while achieving the same benefits as a system incorporating the special cavitation valve.
Claims21
A system for agricultural water oxygenation comprising:
- a source of compressed liquid oxygen coupled to a stream of water for irrigation of crops;
- a pressure sensor coupled to the stream of water for irrigation of crops, the pressure sensor measuring a pressure of the stream of water for irrigation of crops;
- and
- a control device coupled electronically to the pressure sensor such that the control device shuts off a flow of oxygen from the source of compressed liquid oxygen when the pressure sensor detects measures a pressure of the stream of water for irrigation crops that is less than a threshold, and wherein the system injects oxygen into the water without using any compressor, and the source of compressed liquid oxygen provides oxygen at a pressure greater than the pressure of the stream of water for irrigation of crops merely by the change in state from liquid oxygen to oxygen gas.
