Development of Performance Curves for Subsurface Bioreactors

Subsurface Bioreactors are emerging as a potential best management practice for reducing nitrogen loads form tile drained fields. They are attractive because their use requires no modification of current agro technical practices, they do not necessitate taking land out of production, they can be designed to ensure that their use does not result in a decrease in drainage effectiveness, and they require but little maintenance. However, there is a lack of performance data that can be used to develop design standards for this practice.
