The objectives of this study were to find out the influence of an integrated and ecological farming system as well as agrotechnical measures on weed seedbank size in soil and its species composition over the longer period. Field experiments of integrated and ecological arable systems were established. Weed seedbank in integrated system significantly rose up in 1996. In comparison with the year 1990 it was 2.5 times. The soil cultivation did not have a significant influence on changes of weed seedbank. Amaranthus retroflexus dominantly represented all 22 of the determined weed species. There were no significant differences between the systems when using conventional cultivation. Average weed density under conventional cultivation was 24,768 weeds per 1 sguare m in ecological system and was higher by 21.6 % than was the case in the integrated system.
