Abstract: Quantitative and qualitative Soil Organic Matter (SOM) properties were observed in the soil samples of a medium-term field experiment (Cambisol ? Studena, Czech Republic) and an exact field experi?ment (Chernozem ? Gross Enzersdorf, Austria) in the year 2005 considering different soil tillage systems (conventional and minimum tillage). Except the standard parameters, soil organic matter content and quality in particulate water stable aggregates size fractions was additional determinated for Cambisol. Cambisol showed more favourable values of both quantitative and qualitative SOM parameters in minimum tillage system compared to those in conventional tillage system. SOM quality in the water stable aggregates fractions was better in minimum tillage compared to conventional tillage. Cambisol also showed that SOM in aggregates fractions is much more quality compared to SOM in the original soil samples. Chernozem showed higher values of both quantitative and qualitative SOM parameters in conventional tillage compared to those in minimum tillage but the differences are not high. It can be said that Chernozem organic matter reaction to tillage technology changes is slower and of minor rate in comparison with that of Cambisol organic matter. The results of quantitative and qualitative parameters do not conform to the generally recognised values for the Chernozem soil type.
