Opis:: The present studies were carried out on the basis of field experiment on the strongly acidic soil (pH 3.9). The following treatments were applied: liming, fertilization with manure and nitrogen in the form of ammonium (NH₄)₂SO₄ and nitrate Ca(NO₃)₂ forms of nitrogen, as well as sulphate K₂SO₄ and chloride KCl potassium fertilizers. Liming (CaCO₃) eliminated the effect of aluminium mobilization by (NH₄)₂SO₄. Calcium nitrate Ca(NO₃)₂ and potassium salt KCl limited the content of aluminium strongly bound to the soil organic matter.

Opis:: Contribution of clay mineral phase (<2 um) and organic matter to the cation exchange capacity (CEC) of two clayey soils (gleyic black earths from Gniew) was investigated. The XRD analysis showed dominance of illite and mixed laver illite/smectite as well as the presence of smectite, chlorite and trace of kaolinite in the clay fraction of studied soils. CEC of the soils ranged between 22.08-32.64 cmol(+)/kg. After removal of organic matter with 30% H2O2, CEC the above values decreased significantly. However, the CEC of organic and inorganic components is not an additive. This may be explained by the formation of organo-mineral complexes, which might lower the CEC of the soil as a whole.
