Wageningen Soil Conference 2019
Wageningen Soil Conference is pleased to announce a special issue in the European Journal of Soil Science
Special Issue Title: Understanding soil functions: from ped to planet.
In this special issue we will invite papers presented at the Wageningen Soil Conference (2019) and public submission to address the issue of measuring, mapping and evaluating soil functions from ped to planet, with an additional section addressing the synergies and trade-offs which occur between soil functions. The goal of the Wageningen Soil Conference series is to achieve a better understanding of the role of soil in supporting a range of ecosystem services. We consider that the soil contributes to a range of ecosystem services through the provision of five key soil functions; primary productivity, nutrient cycling, habitat for soil biodiversity, water regulation and carbon management for climate regulation. The special issue will follow the conference format with four key topic areas for submission of papers:
- Soil functions for society (land management and policy applications);
- Innovative methods for measuring soil functions (lab, field or sensor technology);
- Modelling & mapping of soil functions across scales (temporal, spatial and social);
- Synergies and trade-offs between soil functions (primary productivity; biodiversity; nutrient cycling; water resources; carbon and climate regulation).
Details on paper submission dates will be announced closer to the conference.
Understanding soil functions
August 27 – 30, 2019
Wageningen, the Netherlands
Wageningen University & Research is delighted to invite you to join us at the fourth edition of the Wageningen Soil Conference. As in previous editions, the aim is to discuss the importance of soils. In the 2019 edition, the focus will be on “Understanding soil functions: from ped to planet”. To do this we will adopt a new style of conference, with traditional conference talks in the mornings, followed by a range of scientific and interactive topic masterclasses in the afternoons (at no extra fee, fee is included in conference fee).

Soil Organic Matter: From changing form to changing function
The science and policy of soil organic matter have undergone large shifts over the last decade, changing the way we have to manage soils and catapulting soil health and carbon sequestration onto the world stage. The demands on soil for securing food production, water quality and mitigating climate change are daunting in the face of concurrent changes in fundamental understanding of the forms and cycles of organic matter in soil. The notion takes hold that rather than the formation of recalcitrant molecules, life traits of soil biota and interactions with the mineral matrix determine the forms and amounts of soil organic matter. This puts biological controls on soil organic matter under scrutiny with a delicate balance of input and mineralization, recognizing that soil is a flow-through reactor of plant carbon rather than a store where carbon can be biologically sequestered for the long term. Indeed, most soil organic matter is of microbial origin and of large molecular diversity in complex spatial arrangement. Recent modelling efforts were able to describe long-term and large-scale soil carbon dynamics using ecological equilibrium theory and without invoking pools with long residence times. The focus on soil biota as agents of both mineralization as well as stabilization of soil carbon appears as a contradiction and emphasizes the concept of ecosystem control rather than stabilization and sequestration for the long term, even though large portions of soil carbon have old radiocarbon ages. This focus also reflects the growing interest in soil health that puts a spotlight on biological functions rather than only on provisioning and storing nutrients. With these described shifts in understanding of form and function of soil organic matter comes the realization that soil ecosystem services require constant care rather than one-time fixes. Soil management is then a continuing commitment requiring policy, regulatory and market mechanisms that finance soil health practices in the framework of climate-smart solutions.

Build your own soil: Micro-structured Soil Chips allow to investigate soil functions at microbial scale
Soils form the foundation of life on earth and are likely the most species dense habitats on our planet. But despite their fundamental importance, soils and their complex microbial communities have historically been one of the most challenging habitats to study because of their blend of diverse materials and organisms in a complex spatial arrangement, and their opacity. We recently developed microfluidic and micro-engineered model systems that simulate the spatial microstructure of soil microbial habitats in a transparent material, which we call Soil Chips. They allow us to study soil functions at relevant micro-scales: Microbial behaviour and interactions in response to a spatially refined habitat with heterogeneous nutrient distribution, and soil functions such as e.g. physical soil carbon stabilization in the labyrinth of the soil pore space. We can colonize our chips with fluorescent microbial strains and fluorescent substrates to e.g. study foraging strategies and organic matter cycling, or with a whole natural soil including the complex microbial community and soil mineral particles. The chips act like a window into the soil, through which we can eaves-drop on a world that otherwise is largely hidden to us: Jostling protists, tsunami-like drying-rewetting events, and fungi with character. Beyond the scientific potential, the chips can also bring soils closer to people and hopefully increase engagement in soil health conservation.

Mapping microorganisms to understand the feedbacks between warming and soil carbon loss at a global scale
By driving the fixation, stabilization and mineralization of soil organic matter, soil organisms regulate the exchanges of carbon and nutrients between the biosphere and atmosphere. Predicting how soil organisms regulate these organic matter pools is central to our understanding of soil fertility, atmospheric composition and climate.
Despite the hyper-diverse nature of soil communities, the exploration of global ecological trends across regions in the last decade is beginning to provide a unified perspective. The immense global communities are generally dominated by a relatively small number of cosmopolitan species that show consistent global patterns of diversity and biomass distribution. Shaped by a combination of environmental filtering, biotic sorting and random dispersal, these soil communities form unique biogeographic patterns that determine how soil organic matter is processed across the globe.
As the global soil ecological data explosion continues, it is critical that ecologists generate a quantitative, spatially-explicit understanding of soil functional group composition, and the variation in trait expression within these distinct ecological pools. This information can be valuable for parameterizing, scaling and benchmarking model projections of global SOM turnover under current and future climate scenarios.

Can we change our agricultural practices in tropical regions? Synergies and trade-offs using the soil functions approach
The Wageningen Soil Conference 2019 offers presentations and posters under four themes:
|Day 1 – Soil functions for society||Land management and policy applications|
|Day 2 – Innovative methods for measuring soil functions||Lab, field or sensor technology|
|Day 3 – Modelling & mapping of soil functions across scales||Temporal, spatial and social|
|Day 4 – Can we understand synergies and trade-offs between soil functions||Primary productivity; biodiversity; nutrient cycling; water resources; carbon and climate regulation|
The Masterclasses include a range of topics linking to the four themes. For example, are you interested in a masterclass in pedometrics, or how to identify nematodes, or would you like to visualise functional land management through augmented reality? See under Masterclasses which Masterclasses are available and choose your preferred Masterclasses when you register. First come, first served!
If you would like to plan a side event or meeting in the afternoon, we can provide you with a room and facilities. Get together with colleagues and discuss future project proposal ideas or have a project meeting, as part of the conference.
Just send us an email: email@example.com
We look forward to welcoming you to Wageningen in August 2019.
