The aim of this work is to show the importance of monitoring and soil hygienic quality evaluation in the Slovak Republic area. In the past, when no emphasis was put on ecology, as it is nowadays, there was an uncontrolled emission of pollutants from different fields of anthropogenic activities. The consequences are manifested also nowadays, but immediate and expensive solutions are needed. In this work the results of the research of soil heavy metals contamination degree as well as their plant availability depended on soil reaction in the area of “Žitný ostrov” have been presented. The choice of this area is related to specific of mentioned the areas above are characteristic by anthropogenic, but also natural (geochemical) contamination and intensive agricultural activity, too. All the soil samples were analyzed to give changeable soil reaction. Analyses on heavy metal in the aqua regia extract (total content), humus content according Tjurin were conducted and bioavailable macronutrients in Mehlich II. leach.
