Abstract
Summary: The distribution of 37 common weed species in eight common Danish crops in response to seven edaphic factors was evaluated using linear logistic regression with adjustment for over‐dispersion. The main effects of soil properties on weed distribution were adjusted for crop type and sample year by the regression. Crop type and soil clay content were generally those explanatory variables that had the greatest influence on occurrence of the weed species, but all other factors examined (sample year, loss on ignition, pH, P, K, Mg and Mn) also had an effect on the occurrence of some weed species.
