Abstract:
The technical requirements on seeding have enormously increased within the last few years. The trend in farming is towards less soil cultivation, which increases the demands on sowing technology. Seed drills have to demonstrate their capability on different areas such as finished seedbeds after plowing, cultivated areas, but partly also on uncultivated areas. The following requirements are a prerequisite for all techniques: optimum seed distribution, soil-mechanical requirements (depth of placement, embedment, coverage), erosion protection, functional reliability and efficiency. From an economic point of view it is necessary that the techniques have low costs. This thesis aimed at getting an overview of the sowing technology used in Lower Austria. In order to get a more differentiated picture, the analysis was subdivided into three regions which are Western, Central and Eastern Lower Austria. Results like the size of the farm and the annual cropland were also included in this thesis. The first part gives an analysis of the actual situation. The machines were subdivided according to certain criteria, properties such as seed placement, longitudinal and lateral distribution, but the quality of the machines and the supply with spare parts were also part of the assessment. Special attention was paid to the evaluation of embedding tools. The second part of the survey was conducted among farmers to find out which machinery they would prefer in case of replacement. Information was collected about the equipment desired by experts when they buy new or replacement sowing machines. Thus, it was possible to identify some trends. The evaluation itself showed that the mechanical mounted seed drill is the unbeatable number 1 in all three regions. Suffolk coulters are still prevalent, but increasingly edged out by disc coulters. Most farmers would prefer roll disc coulters with depth gauges when they buy new machines. Pack top mounted seed drills and trailed versions can be found in the central area, but increasingly in the East. The evaluation of the machines by mechanical and pneumatic sowing systems hardly showed any great differences in terms of longitudinal and lateral seed or corn distribution.
