This project aims to develop options to optimize the specific fuel consumption in cash crop and forage production. While fuel efficiency in passenger cars can be defined easily in liters per 100 kilometers, this is much more difficult in agricultural process chains, where different process steps depend on and influence each other. Additionally, location conditions and yield potentials in agriculture vary very much. For this reason, we will record the specific fuel consumption in liters per unit of grain. EKoTech develops various options for future fuel savings regarding the individual machine as well as the entire production process. "We analyze and evaluate the results in a comprehensive simulation model developed by technical universities, which includes, among other things, our typical farms, and then validate the results in the context of focus group discussions with consultants and agricultural entrepreneurs."
