This method facilitates determination of seven fractions of copper in soil (water-soluble copper (WSC), exchangeable copper (EC), copper bound to inorganic (IC) and organic (OC) soil fraction, occluded copper (OCCLUDC), residual copper (RC) and total copper (TC)). The method was verified on a set of soil samples from the most typical soils of Slovakia, CSFR. Respective results of the minimal, maximal and mean content of copper fractions recorded: WSC 0.04, 0.22, 0.12; EC 0.29, 0.50, 0.38; IC 0.36, 0.89, 0.51; OC 5.0, 24.6, 13.4; OCCLUDC 2.2, 17.7, 9.9; RC 18.0, 41.0, 29.3; TC 36.18, 69.44, 53.66.
