Technical Abstract: Non-point source water pollutants resulting from agricultural areas have been implicated as a source of water quality degradation in south Florida. The nutrient loading from agricultural and urban areas has increased nutrient concentrations, particularly phosphorus at the Everglades National Park. It is reported that nutrient-enriched waters affect vegetation type and patterns. The objective of this study is to investigate the movement of phosphorus and Atrazine in the soils in south Florida. Three typical soils from the region were selected and used for this study. A rainfall simulator was used to study phosphorus and Atrazine transport in surface runoff and leaching through soils. The results indicate that there is a significant interaction between differnt soil type on the movement of agro-chemicals.
