List of breakout sessions with description

Session 1

Carbon sequestration and trade-offs

(this session will be split into two sessions, more information on the concept will soon be available)

  • Session conveners: Felix Seidel (Thuenen, CarboSeq project), Alessandra Lagomarsino (CREA, SOMMIT project)
  • Internal EJP SOIL projects with main link to this theme: CarboSeq, SOMMIT, TRACE-SOILS, INSURE
  • Description
    Carbon sequestration in agricultural soils is a strategy that can contribute to mitigate climate change. The key for soil carbon sequestration is having a positive balance between carbon inputs and outputs. Enhanced inputs of organic matter to the soil can be achieved by improved management options, such as minimizing soil disturbance, use of cover crops, incorporation of crop residues, addition of organic matter, or optimization of varieties with increased root biomass. In cultivated peat soils, rewetting is needed to decrease carbon outputs and therefore achieve carbon sequestration.

    Increasing soil organic carbon has several co-benefits, beyond climate change mitigation, including improvement of soil health, fertility and water holding capacity. On the other side, agricultural strategies aimed at increasing carbon sequestration affect soil N2O, CO2 and CH4 fluxes, and N leaching. These trade-offs of carbon sequestration may hamper climate change mitigation efforts. Thus, the overall effect of management practices needs to be evaluated to appropriately quantify their environmental impact. 

    In this session, we welcome contributions that give insights into the topic of soil carbon sequestration in agricultural lands. A special focus will be given to management practices affecting this process, as well the trade-offs (especially N2O and CH4 fluxes as well as N and P losses) associated with changes in soil carbon.

Landscape approaches for soil health and ecosystem services

  • Session conveners: Lisbeth Johanssen & Elmar Schmaltz (BAW, SCALE)
  • Internal EJP SOIL projects with main link to this theme: SCALE
  • Description
    Sustainable land management at different scales requires consideration of the multifunctionality of landscapes, in which natural resources management may compete with environmental and socio-economic demands. The multiple land uses and involvement of multiple stakeholders call for an integrated approach between policy and practice to maintain or improve soil health and ecosystem services.

    As different landscape elements are often linked to each other, the concept of connectivity throughout the landscape becomes very important. For example, in the context of soil erosion, water and sediment transport from an agricultural field to other landscape elements such as water courses or infrastructure depends on the connectivity within environmental systems or landscapes. Additional knowledge of surface processes at multiple scales and across landscape elements is needed. Only in this way, is it possible to ensure resilience of the landscape through the implementation of mitigation measures and policy adaptation.

    In this session, we focus on landscape approaches related to soil conservation, soil erosion as well as sediment and hydrologic connectivity and would like to invite interested parties to submit an abstract with results on novel research.

Session 2

Roots and carbon sequestration

  • Session conveners: Rebecca Hood-Nowotny (BOKU, MaxRoot C), Isabelle Bertrand (INRAE, MixRoot C)
  • Internal EJP SOIL projects with main link to this theme: MaxRoot C, MixRoot C, CarboSeq T9.2
  • Description
    Roots are the hidden part of plants. Because they i) decompose slower than aerial plant parts, ii) produce C through rhizodeposition and turnover, and iii) colonize subsoils, they drive soil microbial activity and contribute to soil fertility and mitigate climate change through C sequestration in soil.

    Despite the importance of these processes, our current knowledge on soil-root interactions in agroecosystems is poor. How root biomass and traits relate to soil nutrients and C contents in shallow and deeper soil horizons needs to be better investigated. What are the main root traits related to SOC? Are the predictors different in mixed versus single species agroecosystems? How varietal selection may impact root biomass, C stocks and drought resistance? Do cover crops increase C stocks in the different soil horizons? Do diversified agroecosystems have a higher potential for soil C sequestration, what is the relative contribution of roots? In different agroecosystems what are the main tradeoffs between root C inputs and yield? How to model root C contribution to soil? All these research questions still need to be addressed.

    In this session we will welcome all results focusing on soil and root interactions in agroecosystems. Contribution from students are highly welcome.

Climate change adaptation and innovative practices

  • Session conveners: Frederic Vanwidekens (CRAW, i-SoMPE), Guillaume Blanchy (ILVO, CLIMASOMA)
  • Internal EJP SOIL projects with main link to this theme: i-SoMPE, CLIMASOMA, SoilCompac
  • Description: Sustainable agricultural management practices are needed to improve ecosystem services and minimise threats on soil and water ressources in the context of climate change adaptation. This session will focus on three main aspects of this topic: (i) the development of innovative or established agricultural practices, their expected benefits and possible limitations (e.g. case studies); (ii) the evaluation of the effect of innovative practices and systems of practices on measured productive and environmental variables; and (iii) the dynamics of dissemination of these practices and the identification of the drivers and barriers related to their adoption by farmers.

Bridging Proximal and Remote Sensing for Soil Properties mapping and Monitoring

  • Session conveners: Emmanuelle Vaudour (INRAE, STEROPES), Mogens Humlekrog Greve (AU, SENRES)
  • Internal EJP SOIL projects with main link to this theme: STEROPES, SENSRES, Probefield
  • Description
    Traditional mapping and monitoring methods are expensive and time consuming, and much faster, high throughput methodologies of soil characterization are needed to meet the needs of soil policies and agricultural management. Remote and proximal sensing include a number of methods and techniques that allow for collecting soil information over larger areas or denser than what could be achieved using traditional soil sampling methods. Where a proximal sensing approach can capture spatial variation in the smaller scale (e.g. within field), remote sensing has the advantage of managing both detailed and larger scales (e.g. regional or even nation). Using the advantages in the two approaches, linking proximal and remote sensing techniques can be a way for both up and down scaling and to improve model performance.

    In the session, we aim to discuss current understanding and knowledge gaps around the possibilities of using, and possibly linking, remote and proximal sensors for soil monitoring and/or soil mapping
