Artificial N Sinks

 

In watersheds that generate elevated delivery of agricultural nitrogen (N), constructed wetlands or denitrifying bioreactors hold great promise in sustaining agricultural productivity while also protecting the water quality. These systems are positioned to intercept drainage waters or N-rich groundwater and promote denitrification, the conversion of nitrate to N gases.

Our project seeks to advance the adoption and strategic placement of appropriate bioreactor and constructed wetland designs.  This website and its accompanying International Atlas are our mechanisms to deliver guidance and synthesis materials, fact sheets, case studies, presentations, and other basic information about bioreactors and constructed wetlands. 

We also maintain a listserv for these artificial nitrogen sinks.  To be added to the listserv, email Kelly Addy.
