Abstract/Contents:"The objective of the investigations described in the paper consisted in finding out the effect of industry-like production methods on grassland ecosystems from the plant-sociological, ecological, and agricultural points of view. In 1954, grassland phytocoenoses in the Elbe river valley near Dessau and in the Mulde river valley near Wurzen had been the object of geobotanical investigations. These investigations were repeated in 1976. Sprinkler irrigation, intensive eutrophication, and the inclusion of grazing resulted in a complete change of the ecosystems. The productiveness of the swards improved substantially both in quantitative and qualitative respect, and the number of species declined strongly. The latter concerned above all the species having a rather narrow ecological range, whereas several common and demanding meadow plants, above all grasses, in part reached a much higher share in the overall herbage yield. Both the soil reaction and the soil nutrient potential had improved significantly."
