The field experiments were carried out over 1996-98 at the Research Station of the Faculty of Agriculture at Mochelek in the vicinity of Bydgoszcz (Poland), on a very good rye complex soil. The research covered five non-papilionaceous plant species: white mustard, radish, winter rape, sunflower and tansy phacelia, grown in stubble intercrop after winter wheat. Three plant fertilization variants were used: cattle slurry, wheaten straw with mineral fertilizers added and mineral fertilizers exclusively. The research showed a high potential of non-papilionaceous plants to accumulate macroelements unused by plants cultivated as a forecrop. All the plants accumulated much more nitrogen and potassium in its biomass than the amount of their intake in a form of fertilizers. The substantial part of the matter of the nutrient uptake was accumulated in the overground biomass of plants cultivated in stubble intercrop. The greatest macroelements accumulation potential was recorded for radish
