Abstract:Soil testing and formulated fertilization decisionmaking support platform was established by using componentoriented technology. The component system， as a highlight of this platform， was discussed in detail. At the platform analysis cycle，the workflow of soil testing and formulated fertilization was divided into different business units， and as the mapping result of business units， corresponding business components were developed， methods of constructing componentsbased and ondemand soil testing and formulated fertilization decisionmaking support system were also provided. Finally， advantages of componentsbased soil testing and formulated fertilization decisionmaking support system， such as lower cost and shorter system development cycles， easier deployment in different areas， etc.， were discussed by a practical example.......
