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.

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.



5th Annual Meeting of SPP 1685


The Annual meeting of SPP1685 took place October 9-12, 2017 at the "Evagelische Tagungsstätte" in Hofgeismar. (Hesse).



Virtual Issue: Advances in Phosphorus Research in Forest Ecosystems - now avialable online




The Journal of  Plant Nutrition and Soil Science has compiled a virtual issue 'Advances in Phosphorus Research in Forest ecosystems'  consisting of  12 research articles published in frame of the SPP 1685 during the first funding period.



SPP 1685 - Kick-off meeting 2nd phase 2016


The Kick-off meeting of SPP1685 was held October 17-19, 2016, at the Evangelische Akademie Tutzing (Bavaraia).



OP2016 - Talks available on YouTube


Following on from the successful meeting held in Panama in 2013, the Organic Phosphorus workshop 2016 took place 5th - 9th September 2016 in the Lake District, England. The workshop brought together soil, water, plant and environmental scientists to study and share ideas and innovation on the subject of “Organic Phosphorus in the Environment: Solutions for Phosphorus Security”. The SPP 1685 was represented by several members presenting their work.

Most tals are now available on the YouTube Channel 'OP2016'.

Special Issue - Plant and Soil: Phosphorus in Soils and Plants - Facing  Phosphorus  Scarcity

 Plant and Soil

Phosphorus is a fundamental nutrient for primary productivity of ecosystems and agricultural production, but its misuse impacts agricultural sustainability and has important environmental consequences. Access to global reserves of phosphate rock is politically sensitive and economically challenging. Phosphorus accumulates in agricultural soils, representing a financial loss to farmers and increasing the risk of loss to water. The challenges facing phosphorus sustainability are varied, but many solutions are to be found in the plant–soil system.

Special Issue Plant and Soil.


IUFRO 125th Anniversary Congress 2017 (Freiburg, Germany) - SPP 1685 session on forest floor


The congress provides a platform for the exchange of scientific knowledge across all scientific disciplines relevant in forest research and is open to all scientists regardless of their current affiliation to IUFRO. Abstracts highlighting innovative, interdisciplinary research approaches and the transfer of scientific knowledge on critical global forest-related challenges to national and international policy agendas are encouraged.

Topic 18: "Forest floor matters – The pivotal role of a forest compartment in danger of extinction" is organized in the framework of SPP 1685.

Submit your abstract now at IUFRO 2017 - Abstract submission.

IPW9 - International Phosphorus Workshop 9



July 087-12, 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.
