Sediment source fingerprinting is a relevant tool to support soil conservation and watershed management in the context of accelerated soil erosion. To quantify sediment source contribution, it requires the selection of relevant tracers among the analysed properties. We compared the most conventional method, so-called three-step method, and the newly proposed consensus method. These methods resulted in very contrasted contribution trends, highlighting the importance of conservativity assessment.

This study assessed the long-term impact of water- and tillage-induced soil redistribution on SOC dynamics on a regional-scale catchment (ca. 200 km2). Large-scale and long-term soil redistribution modelling is necessary to explain today’s SOC pattern in young moraine landscapes. Tillage erosion was found to be an underestimated driver of SOC dynamics in areas with long (several centuries to millennia) agricultural history.

Patchy agricultural landscapes have a large number of small fields, which are separated by linear features such as roads and field borders. When eroded sediments are transported out of the agricultural fields by surface runoff, these features can influence sediment connectivity. By use of measured data and a simulation model, we demonstrate how a dense road network (and its drainage system) facilitates sediment transport from fields to water courses in a patchy Swiss agricultural catchment.

A carbon transport model was adjusted to study the importance of water and tillage erosion processes for particular MP transport across a mesoscale landscape. The MP mass delivered into the stream network represented a serious amount of MP input in the same range of potential MP inputs from wastewater treatment plants. In addition, was shown that most of the MP applied to arable soils remains in the topsoil (0–20 cm) for decades. The MP sink function of soil results in a long-term MP source.

We analyzed more than 440 000 measurements from suspended sediment monitoring to show that suspended sediment concentration (SSC) in large rivers in Germany strongly declined by 50 % between 1990 and 2010. We argue that SSC is approaching the natural base level that was reached during the mid-Holocene. There is no simple explanation for this decline, but increased sediment retention in upstream headwaters is presumably the major reason for declining SSC in the large river channels studied.

Through a laboratory incubation experiment, we investigated the spatial patterns of specific maximum heterotrophic respiration in tropical African mountain forest soils developed from contrasting parent material along slope gradients. We found distinct differences in soil respiration between soil depths and geochemical regions related to soil fertility and the chemistry of the soil solution. The topographic origin of our samples was not a major determinant of the observed rates of respiration.

The African Tropics are hotspots of modern-day land use change and are of great relevance for the global carbon cycle. Here, we present data collected as part of the DFG-funded project TropSOC along topographic, land use, and geochemical gradients in the eastern Congo Basin and the Albertine Rift. Our database contains spatial and temporal data on soil, vegetation, environmental properties, and land management collected from 136 pristine tropical forest and cropland plots between 2017 and 2020.

In deeply weathered tropical rainforest soils of Africa, we found that patterns of soil organic carbon stocks differ between soils developed from geochemically contrasting parent material due to differences in the abundance of organo-mineral complexes, the presence/absence of chemical stabilization mechanisms of carbon with minerals and the presence of fossil organic carbon from sedimentary rocks. Physical stabilization mechanisms by aggregation provide additional protection of soil carbon.

Soil greenhouse gas (GHG) fluxes were measured monthly from nitrogen (N), phosphorous (P), N and P, and control plots of the first nutrient manipulation experiment located in an African pristine tropical forest using static chambers. The results suggest (1) contrasting soil GHG responses to nutrient addition, hence highlighting the complexity of the tropical forests, and (2) that the feedback of tropical forests to the global soil GHG budget could be altered by changes in N and P availability.

This study demonstrates the usability of fallout radionuclides 239Pu and 240Pu as a tool to assess soil degradation processes in tropical Africa, which is particularly valuable in regions with limited infrastructure and challenging monitoring conditions for landscape-scale soil degradation monitoring. The study shows no indication of soil redistribution in forest sites but substantial soil redistribution in cropland (sedimentation >40 cm in 55 years) with high variability.

Soil redistribution by water and tillage erosion processes on arable land is a major threat to sustainable use of soil resources. We unravel the role of tillage and water erosion from fallout radionuclide (239+240Pu) activities in a ground moraine landscape. Our results show that tillage erosion dominates soil redistribution processes and has a major impact on the hydrological and sedimentological connectivity, which started before the onset of highly mechanised farming since the 1960s.

Policy to conserve thinning arable soils relies on a balance between the rates of soil erosion and soil formation. Our knowledge of the latter is meagre. Here, we present soil formation rates for an arable hillslope, the first of their kind globally, and a woodland hillslope, the first of their kind in Europe. Rates range between 26 and 96 mm kyr−1. On the arable site, erosion rates are 2 orders of magnitude greater, and in a worst-case scenario, bedrock exposure could occur in 212 years.

An 8-year dataset of erosion monitoring (e.g. agricultural management, rainfall, runoff, sediment delivery) is made available. It covers 14 adjoining and partly nested watersheds (sizes 1–14 ha) that were cultivated following integrated (4 crops) and organic farming (7 crops and grassland) practices. Drivers of erosion and runoff were determined and with high spatial and temporal detail. The data set closes the gap between plot research and watershed research.

Model-based analyses of the effect of soil erosion on carbon (C) dynamics are associated with large uncertainties partly resulting from oversimplifications of erosion processes. This study evaluates the need for process-oriented modelling to analyse erosion-induced C fluxes in different catchments. The results underline the importance of a detailed representation of tillage and water erosion processes. For water erosion, grain-size-specific transport is essential to simulate lateral C fluxes.

This study presents a model that accounts for preferential erosion and transport of sediment and soil organic carbon in agricultural landscapes. We applied the model to a small catchment in Belgium for a period of 100 years. After a thorough model evaluation, these simulations shows that sediment and carbon export are highly episodic and that the temporal variability is largely influenced by selective erosion and deposition.

Quantifying soil redistribution rates is a global challenge. Radiogenic tracers such as plutonium, namely 239+240Pu, released to the atmosphere by atmospheric bomb testing in the 1960s are promising tools to quantify soil redistribution. Direct validation of 239+240Pu as soil redistribution is, however, still missing. Here, we used a unique sediment yield time series in southern Italy, reaching back to the initial fallout of 239+240Pu to verify 239+240Pu as a soil redistribution tracer.

The response rate of soil organic matter (SOM) to the amount of straw return was inversely proportional to the initial SOM and the sand contents. From paddy to dryland, the SOM loss decreased with the increased amount of straw return. The SOM even increased by 1.84 g kg-1 when the straw return amount reached 60–100%. The study revealed that straw return is beneficial to carbon sink in farmland and is a way to prevent a C source caused by the change of paddy field to upland.

Although present in food security key areas, Arenosols carbon stocks are barely studied. A 150-year-old land use change in a Mediterranean Arenosol showed a loss from 50 Gt C ha-1 to 3 Gt C ha-1 after grape cultivation. 14C showed that deep ploughing in a vineyard plot redistributed the remaining microbial carbon both vertically and horizontally. Despite the drastic degradation of the organic matter pool, Arenosols would have a high carbon storage potential, targeting the 4 per 1000 initiative.

Tillage practices and traffic management have significant implications for root architecture, plant growth, and, ultimately, crop yield. Soil cores were extracted from a long-term tillage trial to measure the relationship between soil physical properties and root growth. We found that no-traffic and low-tyre-pressure methods significantly increased rooting properties and crop yield under zero-tillage conditions compared to conventionally managed deep-tillage treatments with high tyre pressures.

We have started to address this issue because the application of wetting agents is very widespread within the European Union and is often considered desirable because it increases the effectiveness of pesticides. While pesticides are thoroughly tested for their impact on the environment as a whole, testing for the effects of wetting agents is minimal. Today, there is no research on their impact on the soil environment.

This study found that the influence of argan trees on soil properties in southern Morocco is mostly limited to the area covered by the tree crown. However, the tree influences the bare soil outside the crown positively in specific directions because wind and water can move litter and soil particles from under the tree to the areas between the trees. These findings, based on soil samples around argan trees, could help structure reforestation measures.

Land use changes are an important anthropogenic perturbation that can cause soil degradation, but the impacts of land conversion from growing cereals to vegetables have received little attention. Using a combination of soil analyses from paired sites and data from farmer surveys, we found significant soil degradation in intensive vegetable cropping under paddy rice–oilseed rape rotation in southwestern China. This study may alert others to the potential land degradation in the subtropics.

Pollution of French soils by polycyclic aromatic hydrocarbons (PAHs), known as carcinogenic pollutants, was quantified in this work using an extended data set of 2154 soils sampled across France. The map of PAH concentrations in French soils revealed strong trends in regions with heavy industries and around cities. The PAH signatures indicated the influence of PAH emissions in Europe during the industrial revolution. Health risks posed by PAHs in soils were low but need to be considered.

Long-term conservation tillage results in more complex and heterogeneous activities of soil organisms relative to conventional tillage. This study used an energetic food web modelling approach to calculate the mineralized N delivered by the whole soil community assemblages and highlighted the essential role of soil food web complexity in coupling N mineralization and soybean yield after a 14-year application of conservation tillage in a black soil of Northeast China.

Soil redistribution by water and tillage erosion processes on arable land is a major threat to sustainable use of soil resources. We unravel the role of tillage and water erosion from fallout radionuclide (239+240Pu) activities in a ground moraine landscape. Our results show that tillage erosion dominates soil redistribution processes and has a major impact on the hydrological and sedimentological connectivity, which started before the onset of highly mechanised farming since the 1960s.

The long-term evolution of soil organic carbon in an olive orchard (planted in 1856) was evaluated and compared to an adjacent undisturbed natural area. Total soil organic carbon in the top 40 cm of the soil in the orchard was reduced to 25 % of that in the undisturbed area. The deposition downslope in the orchard of sediment coming from the eroded upslope area did not increase the accumulation of organic carbon in soil, but it quadrupled available phosphorus and improved overall soil quality.

This paper is original research done in north-western Tunisia; it presents the impacts of the topography (slope and aspect) and the land use systems in the SOC storage in a Mediterranean area. It provides a soil spectral library, describes the variation of SOC under different conditions, and highlights the positive impact of agroforestry as good management in improving the SOC. Therefore this finding is very important to support decision making and inform sustainable land management in Tunisia.

Land degradation impacts the health and livelihoods of about 1.5 billion people worldwide. The state of the environment and food security are strongly interlinked in tropical landscapes. This paper demonstrates the integration of soil organic carbon (SOC) and land health maps with socioeconomic datasets into an online, open-access platform called the Resilience Diagnostic and Decision Support Tool for Turkana County in Kenya.

Subsoil compaction is an important soil threat. It is caused by heavy machines used in agriculture. The aim of this study was to estimate how large the area with overcompacted subsoils is in the Netherlands. This was done by selecting locations randomly and determining the porosity and bulk density of the soil at these locations. It appeared that 43 % of the soils in the Netherlands is overcompacted, and so we conclude that subsoil compaction is indeed a serious problem in the Netherlands.

Soil aggregate stability and POM occlusion are integral markers for soil quality. Besides physico-chemical interactions, biofilms are considered to aggregate primary particles, but experimental proof is still missing. In our experiment, soil aggregate samples were treated with biofilm degrading enzymes and showed a reduced POM occlusion and an increased bacteria DNA release compared with untreated samples. Thus, biofilms are assumed to be an important factor of POM occlusion in soil aggregates.

Biodiversity indices for spontaneous grass cover were measured in two olive orchards in southern Spain with contrasting site conditions and management to evaluate their potential for biodiversity metrics of soil degradation. Biodiversity indices were relatively high for agricultural areas. No correlation between the biodiversity indicators and soil quality features were observed. The mere use of vegetation presence as a proxy might mask relative intense soil degradation processes.

Plant roots are crucial in soil erosion control. Moreover, some species respond to nutrient-rich patches by lateral root proliferation. At the soil surface dense mats of roots may block soil pores thereby limiting infiltration, enhancing runoff; whereas at depth local increases in shear strength may reinforce soils at the shear plane. This review considers the potential of manipulating plant roots to control erosion.

Despite gullies having been intensively studied in the past decades, there is no general consensus on such basic aspects as the correct determination of the geometry (width and depth) of these erosion features. Therefore, a measurement protocol is proposed to characterize the geometry of a gully by its effective width and effective depth, which, together with its length, would permit the definition of the equivalent prismatic gully (EPG); this would facilitate the comparison between gullies.

Earthworks carried out before planting a new vineyard caused, in the surface soil layer, an increase in lime and a decline in soil OC and N contents, along with a reduction in the abundance and diversity of microbial and mesofauna communities. Five years after the new vineyard establishment, soil was still far from its original quality and this limited vine development. The reduced OM input resulting from the management and the poor residue biomass was a major factor in delaying soil resilience.

Short summary
Most agricultural soils erode faster than new soil is formed, which leads to soil thinning. Here, we used a model simulation to investigate how soil erosion and soil thinning can alter topsoil properties and change its susceptibility to erosion. We found that soil profiles are sensitive to erosion-induced changes in the soil system, which mostly slow down soil thinning. These findings are likely to impact how we estimate soil lifespans and simulate long-term erosion dynamics.
