It is illustrated and reasons given for, how agricultural production in the major part of central Europe over centuries has been performed with low input and, in general, one-sided and low productive practices. From the 18th century on this traditional agriculture increasingly turned into good yielding, still labour-intensive systems essentially based on legumes like red clover and systematic production of forages and barn yard manure that improved feed and food supply to a growing population. The unique character of this system was manifold, sustainable crop rotations including many different crop species. In the recent past under the pressure of the general economic milieu agriculture was forced to specialize on very few production items and/or crop species with high input of imported feed material and/or mineral fertilizers that of course increased yield but also generated for instance unrecyclable amounts of liquid manure. Further, because of inevitable self-intolerance of any known organism or species, in this type of one-sided production, plant protecting and other chemicals had to become standard production tools. In the article it is pointed out, how life stile and consumer attitudes of our society have strong influence on this intensity of agriculture
