The aim of this study was to evaluate the levels of soil organic matter (SOM) in chernozem in Central Europe and to determine the site specific level for the Czech Republic. Measurements were carried out at selected locations in the Czech Republic from 2003 to 2006 and 141 samples of chernozems were statistically evaluated. Profiles of topsoils (0.0-0.3 m) and subsoils (0.31-0.60 m) were processed separately by descriptive statistics. The average SOM levels in topsoils and subsoils are significantly different (2.73+/-0.07 % vs. 1.94+/-0.07 %). The average SOM level is higher in heavy soils (clayey, clayey-loamy) than in light (sandy) soils. The differences between sandy-loam and clayey-loam soils are significant.
