Keep soil, nutrients out of area water
The pond in a jar demonstration prepared by Gratz is currently displayed in the window sill of the Green County Land and Water Conservation Department, 1627 4th Ave. West, Monroe. Seven jars of distilled pond water and duckweed were treated for three weeks, demonstrating the impact of substances like manure, fertilizer and phosphorous soil, and are available for public viewing.

The results of a "Pond in A Jar" clearly demonstrate the need for retaining nutrients and soil on the landscape rather than allowing runoff into surface waters. For the demonstration, jars were filled with distilled water and approximately an equal amount of duckweed. They were "treated" and the photo shows the results three weeks after treatment.
