The measurements of soil organic matter changes under various forms of land use are needed for the development of sustainable systems. Soil organic matter quality was assessed by HA:FA ratio determined by two fractional methods (Tyurin`s in modification Ponomareva-Plotnikova and by Kononova-Belchikova method). These parameters were determined and assessed in arable soil and in forest soil in locality Cabaj-Capor (south-western part of the Slovak Republic). Analyses of paired samples (cropped and uncropped soil) have shown high difference in total and labile carbon content, and in quality of soil organic matter caused by intensive cultivation. It was observed a decline in total carbon content as an influence of erosion processes and cultivation. Labile carbon can be used effectively to monitor the rate of change in soil carbon
