Spatial and temporal variations in weed seedlings distributions often occur in arable fields and can be assessed and mapped using modern sensor- and information technologies. Both management and site-characteristics can result in the heterogeneity of weed populations. When site-specific weed management decisions were taken based on distribution maps a high potential for herbicide savings was calculated. It was found that for many weed species distribution remained stable over time when site-specific herbicides applications were realized based on economic weed thresholds.
