3.3. SOC content in the eroded loess plateau and slopes of Nałęczów Plateau
The plateau tops and slopes of the Nałęczów Plateau are covered by Luvisols in different stages of erosion (Table 6), which leads to a variation in the depth of the soil profile and of soil properties. In the light of studies on Luvisols conducted by Paluszek (2001) and Paluszek and Żembrowski (2008), the mean thickness of the soil cover on the loess plateau tops and soils is 0.81m, while the mean SOC content in these soils is 0.79% (Table 6). On average, 4 695 432.62 Mg SOC (10 238.39 Mg SOC·km-2, 102.38 Mg SOC·ha-1) of SOC is stored in the soil cover of the slopes and plateau tops (Table 7). Out of that amount, half of the SOC (51.07 Mg SOC·ha-1, 5107.19 Mg SOC·km-2) is stored in the topsoil (average 0 – 0.24 m depth) of the slopes and plateau tops of the Nałęczów Plateau.
