Carbon sequestration in soils is a negative emission technology that can contribute to mitigate climate change. However, for European soils, a comprehensive assessment is missing on how much soil organic carbon (SOC) can be sequestered with different management options using also national data on agricultural management.
The aim of CarboSeq is thus to estimate the feasible SOC sequestration potential considering technical and economic constraints. The project will align with the current FAO activity for a global SOC-sequestration potential map (GSOCseq).
The key for SOC-sequestration is an enhanced input of biomass (e.g. crop residues) to the soil. for which a new database will be built to facilitate model runs with RothC and other soil SOC models for different management scenarios. The potential area of implementation will be developed together with all partners of CarboSeq and the national expert hubs and all partners will run RothC at national levels.
The final product of CarboSeq is the assessment of the European SOC-sequestration potential summarised in an interactive map for Europe. In this map end-users (e.g., stakeholders, or policy makers) can select a set of SOC-sequestration measures along with different target areas, and receive (i) a map that illustrates the amount of additional SOC that could be sequestered by these measures and also (ii) information on potential positive / negative economic / environmental side effects of implementing these measures.
These SOC-sequestration potential maps and data for different management options will guide policy makers regional specific to the most efficient agricultural management options to sequester SOC for climate mitigation.

In this WP, the daily project management and administration activities are executed. The dissemination of the results will be coordinated and aligned to the overall EJP-activities.

In this WP we quantify SOC-sequestration and C-input to the soil effects by cover crops, crops and crops diversification, crop residues, irrigation, reduced tillage as well as hedgerows and agroforestry systems. It will provide input data for assessing the SOC-sequestration potential across pedo-climatic regions and farming conditions in Europe via an intensive data collection.

In this WP, it will be examined to which extent the processing of organic material that is incorporated to soil affects SOC-stocks, considering carbonization (biochar) as well as composting, fermentation and as additional amendment also liming. The goal is to provide emission factors, describe C-input stability changes, suggest model parameters for selected amendments, and identify positive/negative side effects.

In WP4 we quantify changes in SOC-stocks of grassland systems in response to changes in key management drivers: (1) land-use change, (2) grassland management, and (3) management induced plant diversity changes. The main objective is to estimate potential SOC-accumulation under different management drivers across pedoclimatic zones in Europe.

In this WP we assess the effects of the agricultural SOC-sequestration measures on N2O (and where appropriate also CH4 and fossil fuel CO2) emissions in order to create a more complete evaluation of GHG-mitigation effects of SOC sequestration measures.
WP Leader: Thomas Kätterer (SLU)
WP deputy: Lars Elsgaard (AU)
In this WP we will review the literature and compile a dataset on subsoil C stocks measured in long-term field experiments for agroecosystems in Europe. Our specific objectives are to i) prepare a meta-analysis on subsoil SOC stock change rates and assess the influence of soil and climatic factors on subsoil SOC changes, and ii) synthesize soil carbon models that explicitly represent subsoil dynamics and evaluate their sensitivity to changes in stabilization factors with depth.

This work package seeks to assess the impact of waterlogging of mineral soils and/or impeded soil drainage on SOC as well as on component C fluxes and pools across a climatic, land-use and soil-type gradient. We aim at quantifying the influence of water logging on SOC sequestration rates for dieffernt agricultural measures.
WP Leader: Axel Don (Thünen)
WP deputy: Greet Ruysschaert (ILVO)
The aim in this WP is to identify the potential area of implementation for the different agricultural management options across Europe. For each of the agricultural measures for SOC sequestration considered in CarboSeq we want to assess the biophysical, technical and economical constraints that impede their implementation. Together with partners and stakeholders we will discuss these constrains in order to come up with a realistically achievable SOC sequestration potential.

In WP9 we aim (1) to interface SOC simulation models with information on soil, land use, climate, cropping systems, and agricultural management available at European scale and in each involved country; (2) to execute SOC simulation models based on baseline scenarios and SOC-sequestration scenarios, in order to provide in the end a European map of the SOC-sequestration potential. We additionally compile root:shoot data that serve as input data for the models.

To design adequate policies that promote climate mitigation options in agriculture, countries need to know the potential of C sequestration in their conditions, at the national or regional scale, and in particular for agricultural soils. This potential depends on the pedo-climatic conditions, on the current soil organic carbon stocks and on the management practices promoting SOC accumulation that can be implemented.
The project will aim to evaluate the technical potential to store additional carbon in agricultural soils by implementing appropriate agricultural practices in cropland and grassland. Depending on the information available in countries on current SOC stocks, agricultural practices and soil properties, appropriate methodologies should be used, with either Tier 2 or Tier 3 approaches. In addition to a technical estimate, the cost of implementing the different management options should be estimated, in order to evaluate the cost of the quantified SOC additional storage potential in agricultural soils.
Improved spatially explicit quantification of the potential of agricultural soils to sequester more carbon under different cropping, soil management systems and land use change scenarios (e.g. grassland-cropland), in different pedo-climatic conditions, at the regional and national scale, associated with an estimate of the incurred costs. Analysis of the consequences of these options on GHG emissions. Identification of SOC sequestration potentials of the European agro-pedoclimatic regions.
A single project is expected to be funded (large, 3 to 4 years, 350 PM), gathering partners from at least 20 participating member states (Annex 1). A synergistic effort of the different partners is called for. Core activities of this consortium would concern the methodology that can be used, defining a set of reference methodologies to be used. Each involved partner would then perform the evaluation for its own country, using the selected methodology.
Available funding: 4.03 M€
This project should consider outputs of EJP SOIL stocktake T2.4.3. (publication planned by the end of 2020) assessing carbon accounting systems and methods currently used in EJP SOIL countries to estimate SOC storage and storage potentials.
