Colluvial soils as a soil organic carbon pool in different soil regions

Popis výsledku v původním jazyce

Subsoil has been recognized as large reservoir of soil organic carbon in recent years. In our study, we investigated deep colluvial soils as a potentially important source of SOC due to high mass redistribution driven by soil erosion. Three agriculture plots from the Chernozem, Luvisol, and Cambisol regions were studied to assess the SOC storage in topsoil (0-25 cm), at 2 m depth (0-200 cm), and over the total soil depth (0-450 cm) as a function of relief. The study is based on 558 borings, and soil profile description and classification to facilitate the colluvial soil delineation. Among these locations, SOC content was measured at 230 sampling points. Prediction of the SOC stock for the plots was based on support vector machine algorithms using digital elevation model derivatives as predictors. Total SOC stock varied among the study plots. The highest relative SOC stock was measured in the Chemozem (CH) plot (144.7 t.ha(-1)), While at the Luvisol (LU) plot, it reached 68.4 t.ha(-1) a
