Basics of Quantifying N Sources and Fates on the University of Florida Campus

John Cisar, a professor of Environmental Horticulture at the University of Florida's Fort Lauderdale Research and Education Center, is studying how turfgrass and other landscape plants can help prevent nitrogen from leaching through the soil into groundwater, Wednesday - Aug. 13, 2003. He said three years of research have shown that turfgrass is most effective in reducing nitrogen leaching and should be used in Florida landscapes. Other plants require more time to become established and slow nitrogen leaching through the soil.Landscapes, recreational areas, and sports fields are important parts of the University of Florida campus that receive nitrogen (N) fertilization to maintain the health and quality of their plants. However, nitrogen can be lost from the landscape through runoff in storm water or leaching into groundwater, both fates leading to pollution of the receiving water bodies. Human activities can also cause losses of nitrogen. Therefore, educating people about nitrogen cycling in the urban environment is critical for the development of solutions to the environmental problems caused by nitrogen loss. This 5-page fact sheet discusses nitrogen mass budgets, land uses in a major university, and nitrogen sources and fates associated with different land uses on campus.
