Subsurface Bioreactors for Nitrate Removal from Tile Drainage
Subsurface bioreactors are designed for edge-of-field treatment of nitrate-containing tile-drainage. These reactors are packed with carbonaceous material such as corn cobs or wood chips, and are colonized by soil bacteria capable of converting nitrate to nitrogen gas while deriving carbon and energy from the carbonaceous material. We are evaluating existing and novel bioreactor designs to improve performance and reliability of these reactors in the tile-drained landscapes of Iowa. This project is being conducted in partnership with the Iowa Soybean Association.
