The content of soil organic matter in regards to soil texture and land use can be different. We have presumed that the highest soil organic matter content should be noticed in the clayey soils and in native grasslands as well. Therefore, the aim of this study was to characterise soil texture and quantitative and qualitative parameters of soil organic matter and determination of relationship between soil texture and parameters of soil organic matter in generally and with regard to land-use effects. Soil samples were taken from different localities of Slovakia and Poland, always on each locality from arable soil and native grassland. Lesser total (by 25%) and labile (by 13%) carbon contents were determined in intensively cultivated soils in comparison to native grasslands. On the other hand, arable soils had higher quality and stability of soil organic matter than native grasslands. A higher content of sand is the reason of decrease in total organic carbon content (r equal minus 0.606, P less than 0.01). On the other hand, higher content of clay (r = 0.707, P less than 0.001) or silt (r = 0.483, P less than 0.05) is a reason of its increase in soils. A lower content of sand and higher silt content is a reason of increasing soil organic matter stability. The statistically significant effect between soil texture and humic acids stability was observed only in arable soils.
