The purpose of this paper was to describe the reaction of the soil, a chernozemic mixed rendzina, when the no ploughing cultivation was applied to it, as well as the direct sowing. The soil reaction was described in comparison to the physical condition of the soil, based on the results of its water and air properties. The following soil properties were determined: bulk density, total porosity, actual air capacity and the field air capacity, actual air permeability and the field air permeability, actual moisture, field water capacity, productive water retention and unavailable water retention to the plants. Basing on the experiments, which had been carried out, no essential differences were found as for the values of the analysed properties, resulting from the simplified cultivation method. It would be also difficult to point the best cultivation system suitable for the given rendzina, for during the time the experiments had been going on, both worsening and bettering of some of the soil properties was observed. There is, however, no indication of an optimum cultivation system. In consequence, there is a practical possibility to replace the classical cultivation with the no ploughing cultivation method or a direct sewing.
