project to quantify nitrate-N and phosphorus leaching under a variety of circumstances. The research has been completely funded through the Florida Department of Environmental Protection. Sites and researchers include Dr. John Cisar at the Ft. Lauderdale Research and Education Center, Dr. Jerry Sartain (phosphorus) and Dr. Laurie Trenholm (nitrate-N) at the Plant Science Research and Education Unit in Citra, and Dr. Bryan Unruh at the West Florida Research and Education Center in Jay. The research is broken down into various


projects, most of which were conducted at 2 or 3 of the sites. Some of the projects included are:


 nitrate-N leaching due to nitrogen (N) rate and irrigation from newly planted turfgrass;


 nitrate-N leaching due to N rate and sod production soil (muck vs. sand);


 nitrate-N leaching due to N rate and irrigation on established turfgrass;


 nitrate-N leaching due to N source;  nitrate-N leaching due to N rate in the winter in north Florida;


 phosphorus leaching due to phosphorus (P) application rate. Each project was conducted for a period from


2-4 years per site. Here is a brief synopsis of results from some of the main projects in Gainesville.
