The importance of increasing levels of Dissolved Oxygen
Dissolved oxygen (DO) refers to the amount of oxygen that is contained in solution. The amount of oxygen that can be held by water may be influenced by water temperature, salinity, and pressure.
The concentration of dissolved oxygen in water is expressed in milligrams per liter (mg O2/L), parts per million (ppm), or percentage saturation (%O2). Dissolved oxygen levels are considered most important and commonly employed measurement of water quality as well as ability to sustain plants or aquatic life.
Increased levels of dissolved oxygen in water will noticeably increase plant yields, benefit root growth allowing for nutrients to be more readily absorbed, and significantly reduce root diseases such as Pythium which typically thrive in oxygen-poor (anaerobic) environments.
