Abstract The nutrients loading from agricultural and urban areas have increased nutrient concentrations, particularly phosphoms, at the Everglades National Park (ENP). The soils in the region are mainly crushed limestone with low water holding capacity, high permeability, low organic matter, and low fertility. The Everglades-Ago-Hydrology Model (EAHM) has been developed to evaluate the impact of agricultural practices on crop production, water balance and the fate and transport of nutrients and pesticides. Considering the poor soil quality, the model simulation test indicated that the application of 90 to 134 ha-' of compost annually will result in an increase in s
