In 2023, the European Commission released a legislative proposal for a Directive on Soil Monitoring and Resilience which aims to define a legal framework to achieve healthy soils across the European Union (EU) by 2050. A key component of the initial Directive is the mandate for Member States to establish basic geographic soil governance units, refe...
The direction and magnitude of soil organic carbon stock (SOCS) change following land use and land cover change (LULCC) are highly uncertain, largely due to the lack of relevant global soil data. Great efforts have been made to build SOCS database at regional, national and even sub-continental scales following LULCC; however, a comprehensive and op...
Pedotransfer functions (PTFs) are increasingly being used to derive difficult-to-measure or cost prohibitive soil properties from more readily available soil data. Soil texture (ST) is one of the most commonly used predictors in PTFs. Soil texture can be determined in the laboratory or estimated manually by soil surveyors in the field. Soil texture...
We provide six short building blocks to devise adaptable soil definitions. These buiding blocks start from a simple and straightforward metaphor and progressively evolve when adopting geophysical, analytical, biogeochemical, cultural, and services driven points of view. These progressive changes end up with a straightforward, yet most important mes...
Soil compaction is one of the most important and readily mitigated threats to soil health. Digital Soil Mapping (DSM) has emerged as an efficient method to provide broad-scale maps by combining soil information with environmental covariates. Until now, soil information input to DSM has been mainly composed of point-based quantitative measurements o...
Various stakeholders, such as modelers, policy makers, farmers, and environmental regulators need reliable soil bulk density and coarse fragment content data. These two soil parameters are necessary to calculate soil carbon and nutrients stocks, to estimate water availability for plants, or to assess soil compaction. However, measuring these two pa...
Soils are a finite resource that is under threat, mainly due to human pressure. Therefore, there is an urgent need to produce maps of soil properties, functions and behaviors that can support land management and various stakeholders' decisions. Compaction is a major threat to soil functions, such as water infiltration and storage, and crops' root g...

Soil organic carbon (SOC) sequestration is a promising natural climate solution for capturing atmospheric CO2, and it provides crucial co-benefits in improving soil functions and services at the same time. Given that SOC is not a single and uniform entity, a deep understanding of SOC response to environmental changes requires additional information...
Soil bulk density (BD) and coarse fragment (CF) content are needed to assess the change overtime of carbon and nitrogen stocks in soils. Measurements of BD at the beginning and at the end of a given study are needed to calculate stock changes based on equivalent soil mass. However, studies about changes of C and N stocks often bypass the evolution...
There is consensus that equivalent soil mass (ESM) approaches are preferred over fixed-depth (FD) procedures for monitoring changes in soil organic carbon (SOC) stocks. However, ESM is not often implemented, even in cases in which land use induces changes in bulk density. In this presentation, we use data from the first and second campaign of the F...

This work addresses the case where the...
In agronomy, soil organic carbon (SOC) content is important for the development and growth of crops. From an environmental monitoring viewpoint, SOC sequestration is essential for mitigating the emission of greenhouse gases into the atmosphere. SOC dynamics in cropland soils should be further studied through various approaches including remote sens...
Visible-near infrared (vis-NIR) spectroscopy has been widely used to characterize soil information from field to global scales. Before applying a calibrated spectral predictive model to acquire soil information, either independent validation or k-fold cross validation is used to evaluate model performance. However, there is no consensus on which va...
Soil Security includes dimensions, soil capability, soil condition, soil capital, soil connectivity and soil codification (the “five C's”). This article provides a short review on how soil mapping, digital soil mapping and soil monitoring systems (SM, DSM and SMS) over large areas contribute to these five C's at scales ranging from country to globe...
The spatial assessment of soil organic carbon (SOC) is a major environmental challenge, notably for evaluating soil carbon stocks. Recent works have shown the capability of Sentinel-2 to predict SOC content over temperate agroecosystems characterized with annual crops. However, because spectral models are only applicable on bare soils, the mapping...
Increasing soil organic carbon (SOC) stocks is a promising way to mitigate the increase in atmospheric CO2 concentration. Based on a simple ratio between CO2 anthropogenic emissions and SOC stocks worldwide it has been suggested that a 0.4% (4 per 1000) yearly increase of SOC stocks could compensate for current anthropogenic CO2 emissions. Here, we...

It has long been acknowledged that the soil spatial samplings used as inputs to DSM models are strong drivers – and often limiting factors – of the performances of such models. However, few studies have focused on evaluating this impact and identifying the related spatial sampling characteristics. In this study, a numerical experiment was conducted...
Australia has advanced the science and application of Digital Soil Mapping (DSM). Over the past decade, DSM in Australia has evolved from being purely research focused to become 'operational', where it is embedded into many soil-agency land resource assessment programs around the country. This has resulted from a series of 'drivers', such as an inc...
During the last 10 years, several attempts to map soil attributes at the scale of mainland France have been realised. We exemplify them by seven major outputs: maps of organic C stocks, trace elements (TE), microbial density and diversity, soil thickness, available water capacity (AWC), extractable P, and changes in soil pH. We first briefly descri...
