Abstract:
The Decision Support System for Agrotechnology Transfer (DSSAT) has been in use for more than 15 years by researchers in over 100 countries worldwide. The release of DSSAT Version 4 incorporates changes to both the structure of the crop models and the interface to the models and associated analysis and utility programs. The DSSAT crop models have been re-structured and re-programmed to facilitate more efficient incorporation of new scientific advances and form the basis for the DSSAT Cropping System Model (CSM). The CSM design is modular in structure, and individual components are separated along scientific disciplines and are structured to allow easy replacement or addition of modules. The DSSAT package incorporates models of 27 different crops with new tools that facilitate the creation and management of experimental, soil, and weather data files. The interface to the crop models and tools is via a graphical shell interface and includes integrated system updates, program support, and support for uploading and downloading of experimental data and experiments via the internet. DSSAT v4 includes improved application programs for seasonal and sequence analyses that assess the economic risks and environmental impacts associated with irrigation, fertilizer and nutrient management, climate change, soil carbon sequestration, climate variability and precision management.
