http://www.earth-syst-sci-data.net/9/1/2017/ The aim of the World Soil Information Service (WoSIS) is to serve quality-assessed, georeferenced soil data (point, polygon, and grid) to the international community upon their standardisation and harmonisation. So far, the focus has been on developing procedures for legacy point data with special atten...

Capability, a term that has been well defined in welfare economics, can be applied to soil by defining the intrinsic capacity of a soil to contribute to ecosystem services, including biomass production. Seven soil functions are used to define capabilities, and combining different functions in storylines provides integrated expressions for capabilit...

Soil carbon (C) is a critical component of Earth system models (ESMs) and its diverse representations are a major source of the large spread across models in the terrestrial C sink from the 3rd to 5th assessment reports of the Intergovernmental Panel on Climate Change (IPCC). Improving soil C projections is of a high priority for Earth system model...

Present global maps of soil water retention (SWR) are mostly derived from pedotransfer functions (PTFs) applied to maps of other basic soil properties. As an alternative, ‘point-based’ mapping of soil water content can improve global soil data availability and quality. We developed point-based global maps with estimated uncertainty of the volumetri...

There is a growing demand for high quality soil data. However, soil measurements are subject to many error sources. We aimed to quantify uncertainties in synthetic and real‐world wet chemistry soil data through a linear mixed‐effects model, including batch and laboratory effects. The use of synthetic data allowed us to investigate how accurately th...

Poster
Full-text available
Soil is key in the realisation of a number of UN Sustainable Development Goals providing a variety of goods and services. Erosion, decline in soil organic carbon and loss of biodiversity can lead to soil and land degradation, a global challenge for sustainability. It is therefore important to link the ecosystem services approach with the multitude...

> Many studies have shown that agricultural soils have potential to sequester carbon, when judiciously managed, resulting in various initiatives to sequester organic carbon in agricultural lands. Yet, there is still much uncertainty about this potential. The EU H2020 CIRCASA project aims to address this knowledge gap. > The CIRCASA project is impl...
Article
Full-text available
Reported potentials for sequestration of carbon in soils of agricultural lands are overly optimistic because they assume that all degraded cropland and grassland can be subjected to best management practices. Two approaches for estimating this potential are presented. Method 1 (M1) considers literature‐derived best estimates for annual SOC gains (M...

Full-text available
Characterization of soil water retention, e.g., water content at field capacity (FC) and permanent wilting point (PWP) over a landscape plays a key role in efficient utilization of available scarce water resources in dry land agriculture; however, direct measurement thereof for multiple locations in the field is not always feasible. Therefore, pedo...

Accurate estimation of the global soil organic carbon (SOC) stock and temporal changes therein are of vital importance for climate-change studies. Most current assessments take a model-based approach to predict SOC spatially and aggregate point predictions to a global SOC stock estimate. Estimates of SOC stock dynamics are derived by repeating this...
