Influence of the soil pollution by diesel oil products (in the range 5-50 OOO mg/kg) on the content of available forms of NH4-N, NO3-N, P, and K was studied. Analysis of variance of two-factor experiment showed that the influence of the soil type was higher, followed by the increasing amounts of the oil products, and the combination of these two factors (soil and pollutant). The changes in the studied available forms content increased in the range: K, P, NH4-N, and NO3-N. The resistance of the soils to that influence decreased in the range: Calcareous Chernozem, Leached Smolnitza, Pseudopodzolic, Alluvial-meadow. It was concluded that the decrease of the available forms content was due to the increased anaerobiosis in the polluted by oil products soils.
