- The research area is located in the Bytów District (NW Poland). The following analysis were performed: thickness of the humus horizon, reserves of humus, soil reaction, the acid and alkaline cations in soil adsorbtion complex and hulk density. The conducted researches revealed that the application of agricultural machinery caused erosion acceleration, particularly in the hilly areas. The deluvial horizons of these areas reach thickness of 50-100 cm. They are richer in organic matter than humus horizons located on flat-topped mountains and slopes. Discussed deluvial horizons are also characterized by less acid reaction, sometimes even neutral, and higher saturation of the soil adsorbtion complex. It was also observed that longstanding mechanization of agriculture leads to formation of a densified layer at the depth of 30 cm. The intensive fertilization with mineral fertilizers, especially nitric ones, causes soil acidification.
