(SOC average 4.3 ± 0.2 g kg−1) due to a passed tillage practices that uniformed the surface soil layer. After the implementing of C4 soil strip, which was rich in SOC content (8.6 ± 0.6 g kg−1), the SOC in the 0–15 cm depth changed significantly along the plot. The SOC was highest in the upper tram of the plot (4.8 ± 0.2 g kg−1) and lowest in the lower tram of the plot (4.1 ± 0.1 g kg−1). SOC content in the 15–30 cm depths did not significantly change among the plot positions and with the SOC content before the plot installation. Such results indicated a movement of C only along soil surface of the plot and consequent accumulation of OC in the soil and an increase of the DOC concentration in the collected runoff. The sediments were richer in OC in comparison to the average SOC content in the plot. The OC content in sediment ranged between 7.5 g kg−1 to 18.4 g kg−1. The enrichment ratio between the average weight of the OC in sediment and SOC in the plot was 1.9. The DOC in runoff ranged between 3.70 mg kg−1 to 7.35 mg kg−1 during the observed period. For each square meter of the plot, after 71 days of observation, 2.08 g of sediment OC and 0.12 g of DOC were lost off site.
