Conference proceedings 1997tical models and computer simulation provideobjective tools for applying science to determine and evaluate optionsfor resource management at field, farm and regional scales. However,these tools would not be fully utilizable without incorporating socialand economic dimensions into their application.

Energy Economics and Financial Marketsction; animal weight gain, reproduction, and import and export of nutrients through fertilizer, purchased feed, milk, and animal sales are accounted for. Rations for animals leading to zero excess manure phosphorus at best economic return are identified by simultaneously minimizing excess manure phosphorus, feed cost and cropland requirement.

Energy Economics and Financial Marketsn the expert system using a yes/no decision tree framework. Preliminary verification of the system prototype using data from the Dominican Republic and evaluation of the system by potential users suggest that it is logically consistent, reasonably accurate (83% for tree orchard; 68% for contour hedgerows) and potentially useful.
