Experiments were conducted on four arable fields in order to study the spatial and temporal dynamics of weed populations under the influence of site-specific weed control from 1997 until 2003. Winter wheat (ww), winter barley (wb), maize and sugar beet (sb) were rotated in the experimental fields. Data of weed population dynamics collected in the field experiments were fitted into a weed population model. Distribution of Chenopodium album in two fields was predicted based on previous year weed distribution maps. The predicted and observed distributions significantly correlated using Pearsons correlation coefficient.
