"During 1996-2000 the secondary succession on a field left fallow was investigated. The experimental area was divided into a ploughed and unploughed part. Both parts were divided into 5 x 5 m plots that were either left intact (control), mowed in June or July, or superficially cultivated in June. The position of plots was identical each year. The spread of Cirsium arvense (L.) Scop. was increased by ploughing and superficial cultivation. Ploughing stimulated the spread of perennial dicotyledonous plants more than mowing in June and July. Superficial cultivation increased the spread of perennial dicotyledonous plants in the first years. Later on the proportion of perennial dicotyledonous plants decreased and after 5 years the plots were dominated by Anisantha sterilis (L.) Nevski. The incidence of Elytrigia repens (L.) Desv. was highest in the 5th year on unploughed control plots. The spread of perennial monocotyledonous plants was lowest in ploughed and superficially cultivated plots."@cs .
