A CONSTRUCTED VERTICAL MACROPHYTE SYSTEM FOR THE RETENTION FO NITROGEN IN AGRICULTURAL RUNOFF

摘要

Recent evidence for the importance of luxury rhizome accumulation of N by the common reed Phragmites australis opens the possibility for N retention in constructed vartical wetlands. The removal of nutrients (N and P) from agricultural runoff was investigatedin columns planted with P. Australis in a sand bed.
