New Research Topic: Changes in Forest Ecosystem Nutrition

Contributions are welcome!


 Frühling BBR

About the Research Topic

Continued deterioration of phosphorus supply and changes in nitrogen dynamics in forest ecosystems has been emphasized in recent ecosystem studies. Detrimental consequences of any such nutrient based changes in forest ecosystems are expected because of the tight feedbacks on climate change mitigation and adaptation. Globally, forest change and associated changes in nutrient supply are perceived to be results of multiple factors including rising temperatures, more frequent weather extremes, continued high N inputs, decreasing biodiversity, and increased intensity in forest management practices. Traditional approaches of plant nutrition are not entirely sufficient for the assessment and evaluation of interactions between nutrient supply and forest change. For example, they fail to address essential aspects such as the nutrient mobilization and demand by microorganisms, the interactions among trees of different species identity or ontogenetic stage, or between other organisms such as herbs, microorganisms, and herbivores. The feedbacks between living organisms and soil properties and their impact on nutrient dynamics, and the interactions between hydrological and biogeochemical cycles remain also poorly understood.

In this Research Topic, we invite submissions addressing all facets of a novel, holistic “ecosystem nutrition” approach. Ecosystem nutrition combines the concepts of nutrient cycling, biogeochemistry and ecosystem ecology, thereby integrating processes at different spatial and temporal scales and in different ecosystem compartments as well as interactions and feedbacks associated with the nutrition of an ecosystem. Thus, this Research Topic has a wide focus on novel advanced concepts, methods and results ranging from the molecular to the ecosystem and landscape scale. Furthermore we are looking for contributions investigating the spatial heterogeneity of forest ecosystems, as well as their medium and long-term responses to changing nutrition. Finally, modelling approaches for a better understanding of those complex interactions are highly welcome.

Workshop - Water and nutrient fluxes in ecosystems under a changing climate: a tracer-based perspective


November 4 - 6, 2020   Postponed to 2021!
Heidelberg, (Germany)

Workshop Scope

This workshop aims at bringing together hydrologists, soil scientists and ecosystem physiologists who study water and nutrient fluxes in diverse ecosystems using isotope and environmental tracers to better understand the biogeochemical processes and residence times along pathways of the soil-plant-atmosphere continuum.Workshop Scope

Deadline abstract submission: Will be announced as soon as possible.

SPP 1685 Closing Conference 2021


June 7 - 10,  2021
Freiburg, (Germany)

New Approaches to Ecosystem Nutrition - Phosphorus and Beyond

The ecological paradigm of the ‘whole being more than the sum of its parts’ is widely accepted as one of the most fascinating properties of ecosystems. Yet the emergence of nutrient dynamics within ecosystems is rarely addressed.
Join us for the second “Ecosystem Nutrition” conference, the closing event of the DFG Priority Program SPP 1685 which has a special focus on the phosphorus nutrition of forest ecosystems.
The goal of the conference is to broaden approaches of plant nutrition to explore nutrient related processes at the scale of ecosystems.


During the conference we will link key findings from SPP 1685 to studies addressing also other nutrients (e.g., nitrogen and potassium).
Contributions on the processes of ecosystem nutrition, on methodological innovations, new experimental approaches, methods and concepts are highly appreciated.

Important dates

February 15, 2021: Deadline abstract submission & Registration opens
March 15, 2021: Notification of acceptance
April 20, 2021: Deadline registration

 June 27 - July 1, 2021 (tentative)
Tartu (Estonia)

10th International Symposium on Ecosystem Behavior

Due to the Covid-19 pandemic, the organizing committee and the international scientific committee have decided to postpone the conference from summer 2020 to summer 2021.

The focus of BIOGEOMON is on the biogeochemistry of forest and natural ecosystems as influenced by anthropogenic and environmental factors. We invite empirical and modeling studies on fluxes and processes related to the turnover of major and trace elements at the ecosystem, watershed, landscape, and global scale.


1   Nutrient fluxes at catchment level
2   Integration of terrestrial and aquatic carbon fluxes across the landscape
3   Biogeochemistry of lakes and rivers
4   Biogeochemistry of natural and constructed wetlands
5   Remote sensing for modeling of biogeochemical fluxes
6   Fluxes between atmosphere & ecosystems
7   Aerosols and VOCs in ecosystem functioning
8   Methane & nitrous oxide fluxes from trees
9   Biodiversity issues of ecosystem behavior
10 Biogeochemistry of trace elements and micropollutants in ecosystems
11 Soil and microbial processes
12 Ecosystem restoration and rehabilitation
13 Peatland processes

Abstracts submission continued, tentative time for closing March 1, 2021.

Eurosoil 2021


August 23 -27, 2021
Geneva (Switzerland)

Connecting people and soil

Eurosoil 2021 objective is to bring together leading research scientists working on soil related topics and stakeholders dealing with issues of public concern such as soil degradation and consequences of climatic changes. The important bridging role of soil practitioners to translate scientific knowledge into practice will be emphasized.

Postponement Information:
– All accepted contributions to sessions will be maintained for the Eurosoil 2021 congress.
– Contributors will have the opportunity to amend/update/edit their contribution in 2021. Details of the timeline for this process will be communicated once finalised
– The Session Programme will remain the same for the vast majority of the programme, some minor changes and updates will be made and announced in as timely a manner as possible
– The organisers are considering a “late breaking” call for contributions in 2021 – confirmation of this along with practical details will be communicated once finalised.
