Influence of different management regimes and soil cultivations on weeds

This study investigates the effects of different cultivations on weeds by different low management intensity regimes (winter rye - summer rye - fallow). The current investigations show the initial situation for 3 variants of winter rye (with and without undersown crops and fertilisation by dung resp.). The occurring plants of sandy soils such as Papaver argemone, Arabidopsis thaliana, Veronica triphyllos and Erophila verna characterize the endangered plant community Papaveretum argemones, mainly represented by the geographical race with Buglossoides arvensis. A clear heterogenity concerning the testing site is shown by the parameters of vegetation, soil and yields. This is due to different initial states and cultivations. The cultivations have hardly influenced the testing site, while several disturbances in the margins influence the constancy of e.g. Spergula arvensis and Hypochaeris glabra.
