Decision Support System for Arable Crops:  Decision Support System for Arable Crops Slide2:  A common farm database, which will be compatible with existing farm databases. A weather database, which will contain climate data and input from met stations and forecasts. Up-to-date variety and pesticide databases containing NIAB ratings and information on all registered pesticides. An expandable encyclopaedia, containing information relevant to the decisions being supported. A range of plug in decision support ‘modules’ designed to address specific problems. DESSAC will provide an integrated suite of agricultural decision support systems. The system will comprise: Decision Support System for Arable Crops:  Decision Support System for Arable Crops The DESSAC farm database has been designed to hold all farm data relevant to a farmer or advisor’s decision making. Decision Support System for Arable Crops:  Decision Support System for Arable Crops Information about the farm This example screen shows a map of the farm at IACR-Rothamsted, indicating the crops being grown in each field. Decision Support System for Arable Crops:  Decision Support System for Arable Crops Users will be able to input farm data manually, or it will be possible read and write to a pre-existing farm management system automatically.

Decision Support System for Arable Crops:  Decision Support System for Arable Crops DESSAC is designed to be customisable and expandable. Decision support modules are currently under development by leading scientists and agronomists in the field. Modules in the pipeline include: Wheat disease manager, led by Silsoe Research Institute. Oilseed rape pest control, developed by CSL, York. The SUNDIAL nitrogen modeling system from IACR-Rothamsted and HRI. A spring barley management system from SAC, Aberdeen. BYDV prediction and control, developed by CSL and IACR-Rothamsted. More modules are being commissioned. Decision Support System for Arable Crops:  Decision Support System for Arable Crops The first module to be released will be the wheat disease manager. This is being developed alongside the DESSAC system, in a collaborative project involving Silsoe Research Institute, HUSAT, ADAS and IACR-Rothamsted. The module is designed to assist in the choice of fungicide spray mixtures and timings. A brief demonstration of the prototype follows ...
