2.7. Soil properties Top-soil factors (i.e. bulk density [BD], texture and SOC content [SOC C ]) in fluenced runoff coefficient ( Fig. 3 A). Runoff coefficientwas lower in NT relative to CT in sandy soils ( 39%) whereas in clayey soils, runoff coefficient under NT was 33% higher than in CT. In soils with bulk density of 1.2 – 1.6 g cm 3 , runoff coefficient was 22% lower in NT than in CT while no difference was shown in soils with lower bulk density ( 1.2 g cm 3 ). Runoff coefficient under NT in soils of low SOC C was 31% lower compared to CT whereas in soils with >2% SOC runoff coefficient in NT was higher by 35% compared to CT. Soil texture, bulk density and soil organic carbon content in fluenced sediment concentration ( Fig. 3 B). Sediment concentra- tion under NT was lower than CT in loamy ( 71%) and sandy soils ( 53%). Sediment concentration under NT compared to CT was 66% lower in soils with bulk density of 1.2 – 1.6 g cm 3 while no significant differences in sediment concentration were shown in lighter soils ( 1.2 g cm 3 ). Sediment concentration was lower under NT than CT for all SOC C categories, with the largest sediment concentration in soils with 1 – 2% SOC C ( 84%) ( Fig. 3 B). Soil loss (product of runoff and sediment concentration; data not shown) in NT was 75% and 68% lower than in CT in loamy and sandy soils, respectively. Lower soil loss under NT than CT ( 73%) was confined to soils with 1.2 – 1.6 g cm 3 bulk density. Soil loss in NT relative to CT decreased significantly in all examined categories of organic carbon content.
