264 Enhancing and Facilitating Use of Agricultural System Models in Field Research

Oral Session
A03 Agroclimatology & Agronomic Modeling

The session will provide a continuing interaction between modelers and field scientists. The objectives are to enhance the applications of agricultural system models in field research, and to improve simulation of critical processes in the models. The field scientists will be invited to present their experiences with the use of models and improvements needed from their perspective. The modelers will present new developments or enhancements in the models in response to earlier feedback from users and examples of new applications. The topics may also include: value of models as a quantitative systems approach; parameterization and calibration; characterization of variability; and databases.
