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 31. März 2018 eingereicht werden.

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).

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.

Leopoldina-Symposium: Earth surface shaping by biotic processes



February 21-24, 2018 
Leopoldina Nationale Akademie der Wissenschaften, Halle (Germany)

In this symposium international speakers will review how organisms not only respond to the Earth’s surface, but also directly modify and control it to promote their own persistence. Plants and animals can directly control the uxes of energy and ma!er that underlie biogeochemical cycles, gas uxes, sediment transport and form new habitats. Recent recogni on of bio c interac ons with Earth surface processes has led to a new Geoscience paradigm: The Earth’s surface is not only the product of tectonic forces (mountain building) and climate (destroying relief by weathering and erosion), but also through bio c processes that are ac ve over micro- to macroscopic scales. Biota moderates tectonic and climate controls on surface processes and is an equally important player in shaping the Earth.
This symposium will review the findings that triggered this paradigm shift, for example that 1) the actvity of biota extends to great depth (the “deep biosphere”); 2) soil development is related to plant diversity and burrowing animals; 3) plants diverge the ow and evapora on of water; 4) higher plants can induce the uptake of mineral nutrients that vastly exceeds the rock weathering of these elements; 5) vegetation moderates soil erosion; 6) large river floodplains are stabilized by plants.
The symposium will combine geoscience, soil, ecology, hydrology, and geobiology research to discuss how new developments in each of these fields should be employed to quantify the entire chain of Earth surface processes influenced by biotic activities, and how these developments can be used to form predictions of global change.

Registration is now open!

Please register until until 10.12.17 (early bird) or 12.2.18 (regular)

BG 1.6: Interdisciplinary session on the global Phosphorus cycle

Phosphorus (P) is an essential element for life on Earth and is tightly cycled within the biosphere. Throughout geological history, P availability has regulated biological productivity with impacts on the global carbon cycle. Today, human activities are significantly changing the natural cycling of P. Phosphate mining has depleted geological P reserves, while increased inputs of P to terrestrial ecosystems have enhanced fluxes of P to lakes and the oceans.
Direct anthropogenic perturbations of the P cycle, coupled with other human-induced stresses, have impacted numerous environments. Forest ecosystems may be losing their ability to recycle P efficiently, due to excessive N input, extensive biomass removal, and climatic stress. Soils, which serve as the biogeochemical fulcrum of the terrestrial P cycle, have been greatly altered by fertilizer use in recent decades. Changes in the P cycle on land impact on the magnitude and timing of P fluxes into aquatic ecosystems, influencing their trophic state. Burial in sediments returns P to the geological sink, eventually forming economically viable P deposits. Throughout the P cycle, redox conditions play a key role in transformations and mobility of P.
This interdisciplinary session invites contributions to the study of P from across the geosciences, and aims to foster links between researchers working on different aspects of the P cycle. We target a balanced session giving equal weight across the continuum of environments in the P cycle, from forests, soils and groundwater, through lakes, rivers and estuaries, to oceans, marine sediments and geological P deposits. We welcome studies of both past and present P cycling, with a focus on novel techniques and approaches.

6th Symposium on Phosphorus in Soils and Plants - PSP6



September 10-13, 2018 
KU Leuven (Belgium)

 The symposium will be the sixth edition of a long standing and successful series starting in Beijing in 2000 and including subsequent editions in Perth (2003), Uberlandia (2006), Beijing (2010) and Montpellier (2014).

Among the topics that will be dealt with are: phosphorus scarcity, which can limit crop production in many agronomical ecosystems, and management of excess phosphorus, which gives rise to probelms of eutrophicatioj mostly in aquatic ecosystems. The scope of the topics will range from fundamental insights of phosphorus biogeochemical cycles to applications such as crop breeding, fertilizer development, soil management and performance of environmental impact assessments. The conference also aims to attract a large number of scientists from developing countries where phosphorus scarcity is a major issue.

Registration will be open from January 15, 2018, but feel free to already visit our website: http://www.psp6symposium.com
