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.

FowiTa 2018 - Neue Deadline für die Einreichung von Beiträgen



Die Deadline für die Einreichung von Beiträgen für die FowiTa 2018 vom 24.-27. September 2018 in Göttingen wurde verlängert.

Beiträge zu den verschiedenen Sessions können noch bis zum 30. Mai 2018 eingereicht werden.

Nähere Informationen finden Sie unter: www.fowita-konferenz.de





FowiTa 2018 - Session "Der Einfluss von Störungen auf den P Kreislauf von Waldökosystemen"


Aktuelle Arbeiten zeigen, dass Waldökosysteme in gemäßigtem Klima nur wenig P verlieren. Störungen des ökologischen Gleichgewichtes können jedoch zu P Verlusten oder einer Midnerung der P-Verfügbarkeit in Wäldern führen. Zu solchen Störungen gehören "natürliche Ereignisse", wie Windwurf oder Schneebruch, menschlich induzierte Ereignisse wie zunehmende Trockenheit, ansteigende Temperaturen oder N-Einträge sowie nutzungsbedingte Eingriffe (P-Export mit der Ernte, Bodenverdichtung, Kahlschlag, Veränderung der Baumartenverteilung, Kalkung). Im Rahmen der Session "Der Einfluss von Störungen auf den P Kreislauf von Waldökosystemen" soll sikutiert werdene welche Konsequenzen solche Störungen für die P-Versorgung von Waldökosystemen haben, welche Prozesse zu Regeneration des gestörten P-Kreislaufs beitragen und welche Waldökosysteme besonders sensitiv auf derartige Störungen reagieren. Neben dem Erfahrungsaustausch soll auch diskutiert werden, welche abgeleiteten Maßnahmen zum P-nachhaltigen Management von Wäldern beitragen können.

Die FowiTa 2018 findet vom 24.-27. September 2018 in Göttingen statt.

Beiträge zu dieser oder einer anderen Session können bis zum 21. Mai 2018 eingereicht werden.

EGU 2018:  Interdisciplinary session on the global Phosphorus cycle


In 2018 we will celebrate 5 years of the Interdisciplinary session on the global Phosphorus cycle at the EGU meeting in Vienna. During this time your contributions have helped to make the session an annual success, and to foster a broad-based community of phosphorus scientists within EGU.

We would like to invite you to continue these traditions and join us again at the meeting on 8-13 April 2018. Please visit http://meetingorganizer.copernicus.org/EGU2018/session/26380 before 10 January 2018 to submit your abstract.

The conveners:

Tom Jilbert, Friederike Lang, Phil Haygarth, Federica Tamburini, Ben Turner, Jaane Krueger, Tobias Goldhammer




Research into organic phosphorus is key to ensure food security and environmental sustainability


A non-renewable resource, phosphorus (P) is essential for crop and food production. However, due to inefficient use and limited global reserves, inorganic P fertilisers will become less economically viable and there are concerns about future supplies and the environmental consequences of mismanagement. Without action, this situation could undermine agricultural productivity and sustainability.

A large proportion of P is already present in soils in organic forms, which are fundamental for biological and ecosystems functions in the terrestrial environment, as well as cell function, growth and reproduction.

During an Organic P workshop held in the Lake District in September 2016 a group of 102 scientist from 23 countries  - including 10 members of SPP 1685 - agree, that "organic P research has a critical role to play in tackling a number of important global challenges and there are key contributions to be made toward understanding biogeochemical cycles, dynamics and function of natural ecosystems and the management of agricultural systems".

Following the mmetin in the Lake District the paper Organic phosphorus in the terrestrial environment: a perspective on the state of the art and future priorities is published in Plant and Soil. The article is part of a Special Issue of papers associated with the Organic P workshop.
