In 3-year pot experiment the influence of soil liming with calcium carbonate applied in the 1st year at a single dose or in 4 times higher dose (calculated on the basis of soil hydrolytic acidity), with mineral fertilizers, on the level of iron contents in ryegrass was tested. The results of experiment showed that applied fertilizers caused significant changes of iron content in the crop. The content of this element in plants was mostly lower in grass from plots fertilized with calcium carbonate, particularly during first year of the experiment. The influence of superphosphate on iron content varied, and depended on the year of experiment, time of cutting, and CaCO3 dose
