“…This finding is consistent with previous decomposition and other SOC studies that showed that rate of SOC loss through decomposition could be faster on the surface of OM rich and poorly drained depositional landform positions (Berhe, 2012(Berhe, , 2013. In addition to decomposition, SOC loss from the surface soil in the depositional landform position may become stabilized in the depositional landform positions particularly if it is buried by subsequently eroded material (Berhe et al, 2007;Doetterl et al, 2016).…”

“…A number of authors calculated additional C sequestration due to soil erosion (Berhe et al, 2007;Dymond, 2010;VandenBygaart et al, 2015;Yoo et al, 2005), which was explained by the burial of replaced C at depositional sites and dynamic replacement at eroded sites (e.g., Doetterl et al, 2016). This is in accordance with erosion-induced C sequestration postulated by Berhe and Kleber (2013) and Van Oost et al (2007), for example.…”

“…Hence, we were able to confirm that AC-based C budgets are able to reveal small-scale spatial differences and short-term temporal dynamics of SOC. al., 2011;Doetterl et al, 2016;Stockmann et al, 2015;Van Oost et al, 2007;Xiong et al, 2016). Detecting the development of soil organic carbon stocks ( SOC) in agricultural landscapes needs to consider three major challenges: first, the high small-scale spatial heterogeneity of SOC (e.g., Conant et al, 2011;Xiong et al, 2016).…”

Abstract. Carbon (C) sequestration in soils plays a key role in the global C cycle. It is therefore crucial to adequately monitor dynamics in soil organic carbon ( SOC) stocks when aiming to reveal underlying processes and potential drivers. However, small-scale spatial (10-30 m) and temporal changes in SOC stocks, particularly pronounced in arable lands, are hard to assess. The main reasons for this are limitations of the well-established methods. On the one hand, repeated soil inventories, often used in long-term field trials, reveal spatial patterns and trends in SOC but require a longer observation period and a sufficient number of repetitions. On the other hand, eddy covariance measurements of C fluxes towards a complete C budget of the soil-plant-atmosphere system may help to obtain temporal SOC patterns but lack small-scale spatial resolution.To overcome these limitations, this study presents a reliable method to detect both short-term temporal dynamics as well as small-scale spatial differences of SOC using measurements of the net ecosystem carbon balance (NECB) as a proxy. To estimate the NECB, a combination of automatic chamber (AC) measurements of CO 2 exchange and empirically modeled aboveground biomass development (NPP shoot ) were used. To verify our method, results were compared with SOC observed by soil resampling.Soil resampling and AC measurements were performed from 2010 to 2014 at a colluvial depression located in the hummocky ground moraine landscape of northeastern Germany. The measurement site is characterized by a variable groundwater level (GWL) and pronounced small-scale spatial heterogeneity regarding SOC and nitrogen (Nt) stocks. Tendencies and magnitude of SOC values derived by AC measurements and repeated soil inventories corresponded well. The period of maximum plant growth was identified as being most important for the development of spatial differences in annual SOC. Hence, we were able to confirm that AC-based C budgets are able to reveal small-scale spatial differences and short-term temporal dynamics of SOC.

“…Soil organic carbon content can vary based on edaphic and morphosedimentological conditions, in particular in riverbanks with different hydrological, sedimentological and topographical conditions [12][13][14][15]. Sediment transported by currents during freshets, for instance, can modify soil carbon content and result in soil depletion or enrichment [16,17]. In addition, the remobilization of sediment transported downstream can also alter the carbon flow in riparian soils in the catchment [17].…”

This study examines the spatial distribution of the organic carbon found in alluvial soils affected by successive floods. In flood zones, very little is known of the processes associated with the development of soils subjected to frequent flooding, in particular with respect to the accumulation of litter and organic carbon concentrations. The aim of this study is to better understand the distribution of organic carbon based on various hydrological gradients associated with flood recurrence. A digital elevation model was developed from LIDAR data to assess the microtopography of the site, and further delineate floodplains and no-flood zones. Various soil properties were considered in addition to organic carbon, such as pH, soil bulk density, litter, drainage, and topographic levels (elevation). The results show that the soils in the frequent-flood zones (FFz, recurrence of 0-20 years) have significantly less total organic carbon than the soils in the no-flood zones (NFz) and the moderate flood zones (MFz,. Average values obtained for the surface horizons (0-20 cm) vary by 1.74%˘0.85% (FFz), 3.34%˘1.09% (MFz) and 3.54%˘1.77% (NFz), respectively. The absence of ground litter in the frequent flood zones helps decrease the input of organic matter in the surface horizons and progressively results in soil depletion.
