The restriction of the potential quantities results from the requirement of crop rotation of the rapeseed plant. It can only be cultivated economically and within ecological reason every third or fourth year. In contrast with grain or maize, rapeseed is not selfsustaining and monocultures are therefore impossible.
In view of the overproduction of agricultural products prevalent in our region, the cultivation of so-called regenerative raw materials for exclusive use in technology and for their energy opens a reasonable alternative to traditional food production for the agricultural industry. Instead of turning agricultural areas into fallow land due to overproduction, they can be used to produce energy. The cultivation of plants for their energy will then not compete with food production, an apprehension often expressed in connection with the discussion of raw materials. These areas will be available at any time according to the demand for food production - in contrast to permanent fallow.
