We are taking into account the high share of acid reacting portions of emissions (SO₂, N0_x, fly ash from heating plant) and alkaline reacting dusts from sintering, blast furnaces and steelworks. It can be concluded that soil has acid reaction as a result of immissions with all destructive effects. The increased deposition of sulphur initiates evident disrupting effects with special relation to properties of soil.

Resistance of soils against acidification is similar to that of rocks and soil forming substrates. The water regime of soils is an important factor of acidification due to emission effect. Soils in valleys, where rainwater and surplus of nitrogen fertilizers are gathered, are resistant against acidification in the lowest degree. We can state that resistance of soils against acid pollutants is a function of neutralization capacity of attacked soils. Soils in the area of Kosice must be classified among soils with lower resistance.
