Abstract
Steering systems can also be used to the same extent in other federal states. Limiting factors here are mobile phone coverage and a lack of GPS reception in mountain regions. The field size and mechanisation also influence the savings potential. In addition, an overview of the spread of technology in Austria is to be created in order to estimate the potential in agriculture. These country-specific factors will be researched as part of a master's thesis and prepared for submission to the Austrian Energy Agency.
Previous research has shown that the savings potential of steering systems depends on working width, field shape and driving strategy, which is why this was modelled with a very conservative savings factor. In order to capture the potential more precisely, AMA field data and the working widths used are to be integrated into the calculation on the basis of the literature values already researched. For this purpose, field-specific driving strategies are to be modelled and the savings potential is to be calculated on this basis. A study carried out in 2018 showed that for higher working widths and small strokes, the benefits of automatic steering systems are only given by part width section control. On the basis of the model, the use of a part width section control can be modelled and a savings potential of mineral fertiliser can be determined. The models will be validated on the basis of track planning data and machine data from selected farmers. Particularly deviating driving strategies due to logistics framework conditions should be considered in order to estimate a model deviation.
The savings in mineral fertilisers and fuel not only bring economic advantages, but also a reduction in environmental impacts. A suitable method for assessing this potential is Life Cycle Assessment (LCA), in which the potential resource consumption and environmental impacts of a product or service are assessed. Savings potentials are indicated, for example, in CO2 equivalents (influence on the greenhouse effect and thus the climate effectiveness), in energy or as eutrophication potential (eutrophication potential). A positive effect of steering systems can be scientifically proven and can therefore serve as a sound basis for the ministry's decision regarding a funding structure.
