Short-term effectiveness of drain-blocking in suppressing enzymic peat decomposition and DOC export
Report
enzymic peat decomposition and DOC export

It has become evident that there is a general problem of increasing colour in the water draining from areas of accumulated peat in upland Britain. It was agreed in early 2007 to set up a preliminary investigation into the causes of change in colour u...
