Leaching of nitrogen from the rooting zone following urea fertilization and potential

impacts on surface water quality.

Cynthia M. Flint

Final words in Cindy’s thesis: “We conclude, therefore, that if forests are managed in a way that minimizes N runoff to stream water, managed forests are an essential part of maintaining a healthy Hood Canal watershed.”
