Bioreactors and Water Table Management
In some locations, the use of control structures and bioreactors can work hand in hand with water table management to further reduce nutrient loading and provide water management during drought conditions. Water Table Management makes use of a control structure that can be used to manage the level of water above the tile line.
Controlled drainage can be used to raise or lower the water table, depending on the time of year and water needs. This practice can be used to raise the water level after harvest, reducing nitrate loading into surface waters. It can also allow higher water levels to be present if needed during dry growing seasons.
