First announcement: International workshop Organic Phosphorus 2020








From Land to Sea

An interdiciplinary workshop to synthesize recent advances in research on organic phosphorus across ecosystems; from land
to sea and from the tropics to the arctic.

 Following up the last workshop held in 2016 in the Lake District (UK) the next Organic Phosphorus workshop will take place from

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.

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.

Dates & Events


IUFRO 2019 - XXV IUFRO World Congress



September 29 - October 05, 2019 
Curitiba (Brasil)

Forest Research and Cooperation for Sustainable Development

In 2019, for the first time Latin America will host a World Congress of the IUFRO (International Union of Forest Research Organizations). This event will take place in Curitiba, Paraná, Brazil, from September 29 to October 5, and will be organized and coordinated by the Brazilian Forest Service (SFB) and EMBRAPA. Approximately three thousand participants are expected at the event, which will discuss various aspects related to forest research.
The Congress will be a great opportunity to exchange experiences and knowledge on technological innovations, as well as to stay up to date on the latest research findings and trends for the future of forestry and forest research in all areas of the world.
It will also represent a major meeting place for researchers, teachers, students, and professionals in the forestry sector worldwide to come together.

Abstracts will be accepted until 31 December 2018, and authors will be advised if their presentation is accepted by the end of February 2019.

Congress registration and abstract submission is available here: http://iufro2019.com/abstracts-submission/

IPW9 - International Phosphorus Workshop 9



July 8 - 12, 2019 
Zurich (Switzerland)

Putting phosphorus first?
How to address current and future challenges


Phosphorus is an essential element to all living beings. The increasing food demand for a growing human world population, along with globally greater share of animal products in human diets, will increase the demand on phosphorus fertilizers. They are produced from limited mineable rock phosphate deposits, which are located in few countries, resulting in a delicate geopolitical dependence of food production systems. At the same time, globally a large share of phosphorus contained in societal wastes such as urban waste water is not reused for agricultural production. Together with excess and inefficient use of phosphorus in agricultural production, this results in the dissipation of phosphorus into aquatic ecosystems. In consequence, phosphorus has become a major factor in the global change via eutrophication of aquatic systems and by threating the biodiversity in terrestrial systems. Climate change is expected to amplify phosphorus related challenges, e.g,. via increased losses of phosphorus from terrestrial systems, or via increased phosphorus deficiency to crops related to adverse soil moisture conditions.

The aims of IPW9 are to gather scientist and engineers in order to
    - Discuss concepts, which drive research and use of phosphorus in our societies;
    - Review the progress in knowledge and technology related to phosphorus;
    - Define relevant questions for future research and action to solve phosphorus related problems.

These objectives will be addressed in five themes, each from an interdisciplinary perspective, including natural, engineering, socio-economic and political sciences. Novel results and methodologies shall be presented as well as science-to-application case studies.
