Nitrogen over supply is the most important problem in the high yielding agriculture of Germany today. The mapping approach is unable to guarantee appropriate predictions for N-dressings depending on regional weather conditions and site specific plant water stress situations. Realtime Approaches with map overlay may contribute to this problems, first results obtained in the "IKB-Dürnast-project" show a higher N-efficiency which is equivalent to an improved N-consumption by the plants. For on-farm use electronic communication will become a key position in data gathering and in on-the-go application systems. LBS offers the opportunity to realize such a system in a reasonable time within a standardized system environment.     «
