Objectives
Phase 1: The objective
of this project is to implement a web-based decision support (expert) system
that will
combine environmentally sound and economically feasible crop
production practices with production
system-specific information for the
design and implementation of Nutrient Management Plans (NMPs)
and Best
Management Practices (BMPs). We aim to take full advantage of current advances
in computer technology to
link scientific and site-specific information via user-friendly web-based
computer systems that provides optimal nutrient, irrigation and/or other crop
management recommendations. The implementation of this project is based on
object-oriented modeling design. The specific objectives of
this project are to use the modeling tool to simulate nitrogen cycling in
Florida citrus.
Phase 2: Ontology-based simulation modeling of phosphorus transport in sugarcane in south Florida (OntoSim-Sugarcane model).
