| Popis: | The main consequences of human economic activities include: soil erosion, pollution, exhaustion of soil, impoverishment of soil with mineral substances and dehumification. Anthropogenic impacts usually affect all components of the geosystem. As a result of erosion processes, the soil structure changes, its water-physical properties deteriorate; the use of heavy agricultural machinery on the fields contributes to the formation of a plowing shoe with an increased density, which prevents free infiltration of moisture in the soil; contamination of agricultural land leads to the accumulation of heavy metals (HM), radionuclides, benz(a)pyrene, industrial pollutants of organic and inorganic origin, soil pollution with transport and municipal waste. They penetrate in the soil in different ways. Not only soils but also plants growing on them are polluted, through which they enter the body of animals and humans causing various diseases. |
