Project Type: Experimental
Language: English
Summary: A constructed wetland is a marsh built to filter water contaminants. Some wetlands are designed to filter nitrates. Unfortunately, the input of nitrates into a wetland environment results in the release of nitrous oxide. The purpose of this experiment was to construct a greenhouse gas efficient, nitrate-filtering constructed wetland model.

This project is a continuation of last year's experiment. Click here to view the Managing Greenhouse Gas Exchange in a Constructed Wetland Model Part 1 VSF web page.
