Artificial N Sinks

Advancing constructed wetlands and denitrifying bioreactors to abate edge-of field nitrogen losses

new plantings in constructed wetland


Through this integrated research, extension and education project, we seek to advance the adoption and strategic placement of appropriate constructed wetland and denitrifying bioreactor designs, tailored to spatial/geographic conditions and climate regimes while understanding limitations and uncertainties, to remove offsite losses of N from agriculture lands
