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
