Strategien zur Regulierung der Ackerkratzdistel (Cirsium arvense) im Ökologischen Landbau

The field experiment compared two means of soil tillage and examined the response of grain yield of cultivated cereals and population density of Canada thistle. Results suggest that in fields with a marked proliferation soil tillage cannot be expected to considerably reduce Canada thistle. Besides, the data from the first two seasons indicate a significantly lower or comparable grain yield of cereals after reduced tillage.
