We have proposed a novel framework to generate the firstly publicly released 10-m global PCGs map in 2020 derived from Sentinel-2. Results show that the global PCGs area is approximately 14,259.85 km² in 2020, mainly distributed between 30° N and 40° N. China, not only has the largest area of PCGs in Asia but also ranks first worldwide, with a PCGs area of 8,224.90 km², making up 57.67 % of the global and 83.29 % of the Asia. The overall accuracy of our Global-PCG-10 is satisfactory of 92.08 %.

The irreversible trend in global warming underscores the necessity for accurate monitoring of atmospheric carbon dynamics on a global scale. This study generated a global dataset of column-averaged dry-air mole fraction of CO2 (XCO2) at 0.05° resolution with full coverage using carbon satellite data and a deep learning model. The dataset accurately depicts global and regional XCO2 patterns, advancing the monitoring of carbon emissions and understanding of global carbon dynamics.

The impact of land use and land cover change (LULCC) on soil organic carbon stock (SOCS) is uncertain due to limited global data. Despite regional efforts, a comprehensive global SOCS database has been lacking. This study introduces the Global Soil Organic Carbon Stock dataset after LULCC (GSOCS-LULCC), compiled from 639 articles covering 1,206 sites and 5,982 records across five major land uses. This open-access database enables global assessment of LULCC's effects on SOCS dynamics.

Short summary
A new dataset for topsoil bulk density (BD) and soil organic carbon (SOC) stock (0–20 cm) across Europe using machine learning was generated. The proposed approach performed better in BD prediction and slightly better in SOC stock prediction than earlier-published PTFs. The outcomes present a meaningful advancement in enhancing the accuracy of BD, and the resultant topsoil BD and SOC stock datasets across Europe enable more precise soil hydrological and biological modeling.

This study examines soils in the highly industrialized Dunkerque agglomeration in France. Our work reveals the contamination of urban soils by metals from industrial dust, including Cr, Ni, Mo, Mn, Cd and Zn. While Cr, Ni and Mo are relatively stable in soils, Mn, Cd and Zn are more mobile and may pose environmental and health problems. Our findings highlight the need for careful consideration of future land use near industrial emitters, such as allotment gardens, due to these potential hazards.

This study develops a new method to improve the calibration and evaluation of models that predict soil erosion by water. By using advanced imaging techniques, we can capture detailed changes in the soil surface over time. This helps improve models that forecast erosion, especially as climate change creates new and unpredictable conditions. Our findings highlight the need for more precise tools to better model erosion of our land and environment in the future.

Chinese tea plantations are facing soil acidification, nutrient deficiencies, and imbalances. Less than 45 % of tea plantations are of high quality. The status of soil nutrients and pH are closely related to geological and climatic factors, varies among soil types, and significantly shaped by managerial practices such as cultivation period and fertilization strategy. Recommendations are made to tackle soil issues.

In Ethiopia, we studied (a) the effectiveness of low-cost gully rehabilitation measures in reducing soil loss and upward expansion of gully heads and (b) how farmers and communities view gully interventions. The tested low-cost gully rehabilitation measures were effective in mitigating the upward expansion of gully heads and in reducing soil loss. Farmers also perceive success, but scaling-out can be constrained by diverse challenges.

Our long-term modelling study examines the effects of multiple soil redistribution processes on carbon dynamics in a 200 km² catchment converted from natural forest to agriculture about 1000 years ago. The modelling results stress the importance of including tillage erosion processes and long-term land use and land management changes to understand current soil-redistribution-induced carbon fluxes at the landscape scale.

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. We compared the three-step method and the consensus method and found very contrasted trends. The divergences between virtual mixtures and sample prediction ranges highlight that virtual mixture statistics are not directly transferable to actual samples.

Vegetation restoration is an important method of ecological restoration that aims to control soil erosion and prevent soil degradation. Our study suggests that combinations of species such as C. korshinskii and L. bicolor are optimal for improving the soil nutrients and soil erodibility for any slope aspect. This study provides insight into the rational planning of vegetation restoration measures for slopes with various aspects in semi-arid areas of the northern agro-pastoral ecotone.

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.

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.

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.

A laboratory experiment was carried out for 42 d to study co-selection for tolerance of tetracycline (TC), oxytetracycline (OTC), and chlortetracycline (CTC) in soils polluted with heavy metals (As, Cd, Zn, Cu, Ni, Cr, and Pb). At high metal concentrations, the bacterial communities show tolerance to the metal itself, occurring for all the metals tested in the long term. The bacterial communities of the soil polluted with heavy metals also showed long-term co-tolerance to TC, OTC, and CTC.

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.

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.

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.

Short summary
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.

- We present SF3M, a new graphical user interface for implementing a complete 3-D photo-reconstruction workflow based on freely available software, in combination with a low-cost survey design for the reconstruction of a several-hundred-metres-long gully network.
- This methodology implied using inexpensive means, little manpower, in a short time span, being a promising tool for gully erosion evaluation in scenarios with demanding budget and time constraints and reduced operator expertise.

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.

Short summary
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
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.
The response rate of soil organic matter (SOM) to the amount of straw return was inversely...
