Summary
An
expert system that assists growers in selection and application of BMPs
related to water and nutrition in ridge citrus (NUMAPS) will be expanded
and extended to flatwood citrus and sugarcane. NUMAPS combines expert
systems with record keeping, database management, and computer simulation
to offer growers the best advice on nutrient management using a Web-based
software environment that incorporates easily into their day-to-day production
operation management. BMPs in the form of rules are compiled into
a database and displayed in the software as appropriate for on-site decision
making. Computer simulations of the plant, soil moisture, and nutrient
uptake enhance rule-based BMPs by providing more accurate assessments of
water and nutrient utilization and runoff. The system is designed
to optimize yields in an economically effective manner while greatly reducing
the environmental impact of excess fertilizer and water applications.
An
object-oriented modeling design is adopted to provide flexibility to model
water flux and nutrient transport.
