Using 137Cs and 210Pbex for quantifying soil organic carbon redistribution affected by intensive tillage on steep slopes

Vegetation patterns influence on soil microbial biomass and functional diversity in a hilly area of the Loess Plateau, China

“…The values of SOC, TN, and BD increased with increasing 137 Cs concentration, while EC decreased with as soil erosion could directly affect the distribution of SOC, TN, BD, and EC. These results were consistent with those reported by Li et al (2006) who found that 137 Cs could be directly used to quantify dynamic soil organic carbon redistribution.…”

Effects of vegetation restoration on soil organic carbon sequestration at multiple scales in semi-arid Loess Plateau, China

“…With vegetations being restored on middle and upper slope position, soil erosion was also decreased when cover crops were converted to grass or forest cover. It is propitious to SOC accumulation because of increased biomass and vegetation cover and decreased erosion intensity (Gregorich et al, 1998;Li et al, 2006). Except for the erosive rainfall events, topography is one of the major factors controlling erosion and deposition processes.…”

Hillslope and catchment scale soil organic carbon concentration: An assessment of the role of geomorphology and soil erosion in an undisturbed environment

“…There is much to learn how land management and erosion processes affect carbon sequestration and redistribution in many environments (Van Oost et al, 2005;Dai and Huang, 2006;Li et al, 2006Li et al, , 2007. Of the hydrological and SC studies undertaken many have concentrated on forested tropical and subtropical regions or in cool temperate landscapes in Europe, North America and Asia where there is a strong anthropogenic influence (Pennock et al, 1994;Gregorich et al, 1998;Eatherall et al, 2000;Starr et al, 2000;Welsch et al, 2001;VandenBygaart, 2001;Ritchie and McCarty, 2003;Page et al, 2004;Van Oost et al, 2005;Yoo et al, 2006;Li et al, 2006Li et al, , 2007Huang et al, 2007).…”

Investigations of non-tilled agricultural areas or undisturbed hillslopes are few (Yoo et al, 2006) or incomplete (Ritchie et al, 2004).…”

“…Several studies have examined the relationship between SC and soil erosion (Pennock et al, 1994;Palis et al, 1997;Mabit and Bernard, 1998;Pennock, 2000;VandenBygaart, 2001;Ritchie and McCarty, 2003;Polyakov and Lal, 2004;Shukla and Lal, 2005;Van Oost et al, 2005;Li et al, 2006Li et al, , 2007Mabit et al, 2008) using both field and modelling approaches. The environmental tracer 137 Cs has been used in the past to assess the relationship between soil erosion and SC (DeJong et al, 1983;Pennock et al, 1994;Mabit and Bernard, 1998;Pennock, 2000;Ritchie and Rasmussen, 2000;VandenBygaart, 2001;Ritchie and McCarty, 2003;Van Oost et al, 2005;Li et al, 2006Li et al, , 2007Mabit et al, 2008) as the movement of SC is believed to be linked to the movement of the mineral fraction of soil.…”
