Current Competitive Grant

Reconnecting Iowa riparian buffers with tile drainage

Project ID: E2010-01

This 3-year grant for $39,881 was awarded in 2010.

Location: Story county

This project will quantify the removal of nitrate from tile drainage by redirecting a fraction of the tile drainage as interflow through riparian buffers. The researchers are testing whether the buffers will allow for the removal of nitrates through the denitrification and sequestration processes, thereby improving water quality in the receiving stream.
