Nitrogen Fate in drainage ditches of the coastal plain after dredging
Received for publication June 14, 2008. Drainage ditches are a key conduit of nitrogen (N) from agricultural fields to surface water. The effect of ditch dredging, a common practice to improve drainage, on the fate of N in ditch effluent is not well understood. This study evaluated the effect of dredging on N transport in drainage ditches of the Delmarva Peninsula. Sediments from two ditches ...

What is a messenger?
The work horse of water sampling is the simple messenger, the bullet-shaped weight which strikes the trip mechanism and snaps the sampler shut. Send the messenger down the line when you are ready to take your sample – you choose where and when. When you lower your bottle or dredge into the water,it remains open until you close it. Messengers afford nearly foolproof operation – ...
