Soil samples taken from 35 sites with natural occurrence of Burgundy truffle (Tuber aestivum Vitt.) in Western Slovakia were studied. Evaluation of eight selected characteristics described soil chemistry in Slovak sites, were compared with available soil characteristics from three European countries (France, Hungary and Sweden). Variability of soil samples indicates relatively high degree of adaptability of Burgundy truffle on different soil chemical conditions in Slovak Republic and Europe. For black truffles are typical higher pH values from 7 to 8. In compared countries average soil pH values are in range from 6.93 (Slovak Republic) to 7.6 (France) The lowest pH value of soil in Slovak Republic was 6.36. Content of organic matter in soil presented by average humus content was in range from 6.96% (Hungary) to 11.9% (Sweden). The lowest humus content found in Slovak samples was 5.48%. Average content of phosphorus as limiting factor of truffle occurrence expressed by percentage of P2O5 in soil was in range from 0.009% (France) to 0.02% (Sweden). The highest P2O5 content recorded in Slovakia was 0.0703%.
