This publication discusses the “blue dye” test, which is one way that Extension professionals can show homeowners how water and nutrients move through the soil following irrigation. The information should be useful for county agents to demonstrate basic irrigation and nitrogen management practices and their effects on nitrate-nitrogen (N) leaching. This 4-page fact sheet was written by George Hochmuth, Laurie Trenholm, Esen Momol, Don Rainey, Claire Lewis, and Brian Niemann, and published by the UF Department of Soil and Water Science, November 2013.
