Site specific plant production is one main focus in Precision Farming. Current Agricultural BUS-systems (ISO 11783, DIN 9684) use primarily the "mapping approach" for process control in mobile application systems. The "sensor approach", gaining in importance, is implemented almost only proprietary. For the comprehensive approach "Real-time approach with map overlay" a definition is missing until now. The new definition of an "In-field Controller", a better integration of on-line sensors and a modification of process data handling, enable modular and scalable process control systems in compliance with Agricultural BUS-systems. The In-field Controller can supervise, control and document "Infield activities" based on on-line sensor measurements, "overlay maps" and the inclusion of an expert system. The further decisive workstep will be, especially for spatial variable fertilization, the formulation of knowledge and rules for the "mobile expert system", which must be real-time capable. The Open Source program library LBS-Lib offers a solid basis for the realization and test of an In-field Controller.      «
