The effect of farmyard manure, slurry and liquid organomineral fertiliser was compared with the effect of mineral fertilizer applied to maize, rape, sunflower and oat plants in pots. In the first year, the crop yield was more influenced by mineral and liquid organomineral fertiliser than it was by organic treatments, but in the subsequent two years, better results were achieved with organic amendments. The biggest N concentrations were found in crops receiving mineral treatment and organomineral fertiliser. K and Mg contents were the highest in plants fertilised by farmyard manure or slurry. The biggest amounts of Cd in the above ground parts accumulated in rape plants. Cu accumulated mainly in roots, except in rape, whereas Zn and P concentrations depended on the plant species and fertiliser. The fertilisers applied influenced variably soil chemical composition, but they all lowered soil pH.
