3.1. Organic carbon transport and loss
The cumulative rainfall recorded after 71 days after the plot was installed was 145.2 mm and led to a loss of 160.36 ± 13.5 g−2 of sediment and 17.88 ± 3.02 kg m−2 of runoff. The runoff was strongly correlated with the rainfall, and ranged between 0.62 kg m−2 and 2.93 kg m−2 (Table 1). The rainfall erosivity and soil erodibility resulted in relevant changes in OC redistribution. Before the plots were installed, the SOC content was not significantly (P N 0.5) different along the plot
