Abstract
The process costs on the farm are very high, if they are compared with the costs of farms in the east of germany or with intensive grassland management e.g. in,Schleswig Holstein". They are even higher if the yield in energy value is comprised to the evaluation. So the results are causal in context with high machine-costs and unfavourable field-structure on the one side and low yield because of an extensive cultivation on the other side. To reduce this high costs a cost oriented use of technique and the use of modem agricultural systems, - e.g. the use of Conditioners or automotive mowers - could be a possibility. Also a structural change effects an economy of process costs. If an enlargement of fieldsize or a reduction of the farm-field distance is to prefer, it shouldn't be evaluated separately from the aspects of transport-linked and non-transport-linked field operations as well as the investment and the degree of utilisation.
