Using the decision support system for agriculture (DSS4AG) for wheat fertilization

摘要

The DSS4Ag is an expert system under development at the INEEL through the Site-Specific Technologies for Agriculture (SST4Ag) precision farming research project. The system uses artificial intelligence and other computer information technologies to assist in making spatial, site-specific management decisions. Using this decision support system, we generated a variable-rate fertilizer recommendation recipe for a 135 acre wheat (Triticum aestivum L.) field with the goal of optimum economic return, notmaximum yield. The field was split into blocks, alternately fertilized with the variable-rate recipe and with the uniform application method used by the farmer. The DSS4Ag fertilizer recipe reduced fertilizer costs 39.7% and yields 3.3%, which resultedin a net economic gain of 2.8% as compared with the uniform application used by the farmer.
