The success of organic farming results from the need to produce top-quality food and, additionally, to protect the natural environment by applying eco-friendly agricultural practices and abandoning synthetic fertilizers and chemical pesticides. The aim of this study was to assess the impact of organic and conventional production systems on the content of minerals and fatty acids in grain of oat, wheat and hulled and naked barley. Wheat grain from organic farming was characterized by a higher content of Mn and by significantly higher content of Fe, Zn, Ca and Mg when compared to grain originating from conventional farming. The increased availability of potassium in soil, caused by the applied potassium salt fertilization, was reflected in a higher content of this macronutrient in grain of all cereals from conventional cultivation. The tillage system was found not to exert the same effect on the content of Ca and Mg in all the cereals examined. Lower content of iron and zinc was determined in organic grains of barley and oat. Grain from the conventional cropping system (except naked barley) proved to be richer in lipids. Crude oil of organic cereals was richer in the most valuable polyunsaturated fatty acids than that of the conventionally-grown crops The study demonstrated a stronger dependency between the level of the elements examined and cereal species than between the level of elements and cultivation system.
