Invitation to Submit

We are seeking abstract submissions from delegates who wish to present their work to a large international audience.

Abstracts should be aligned with the session topics provided.

All submissions will be subject to peer review, and successful submissions will be offered either an oral (12 minutes + 3 minutes for questions) or poster presentation.

Delegates may elect for either format as a first choice, though oral presentations will only be awarded for abstracts of the highest standard.

Abstracts should be no longer than 300 words in length, and should not contain tables or figures, nor should they be separated into sections. All abstracts will be published on-line at the start of the conference.

We look forward to receiving your abstract.

Presentation Formats

We invite you to submit abstracts in the formats below. While you will be asked to indicate your preferred presentation format when submitting your abstract, the program committee may request an alternative format be considered. The program committee will allocate the format of presentations, taking into account the preference of authors and the balance of the program.


Oral presentations will be allocated 12 minutes for presentation plus 2 minutes for questions and 1 minute for changing over (15 minutes in total).


Posters will be displayed in the catering area for the duration of the symposium. There will be a focused poster session following the sessions on one evening.

Printed posters will be A0 size (84.1cm wide x 118.9cm high) in portrait orientation.


2019 Themes

The conference theme, “Soil Organic Matter in a Stressed World” has the dual objectives of better understanding and quantifying the functions that SOM sustains in both natural and managed systems, and understanding the stressors that impact on both its stability, and its ability to continue to deliver these key ecosystem functions.

When submitting an abstract through the Presentation Portal please identify the stream your submission best fits. Full descriptions of the themes may be viewed at the bottom of the page or by visiting

All abstracts will undergo a peer review process by the program committee. The program committee will allocate abstracts to the program taking into account the quality of each abstract and the balance of the program.

Presenters will be notified by email to confirm acceptance and format of their presentation.

Abstract Details

For each abstract you submit you will be asked to enter the following information:

Presentation title
Preferred presentation format
Name/s of author/s
Affiliation/s of author/s
Indicate the presenter
Short biography of the presenter


A descriptive presentation title of a up to fifteen words; please only capitalise the first word and proper nouns in your title.


The names, professions, organisations, suburbs, states and email addresses (optional) for each author. Indicate the presenting author in bold.


An abstract of 300 words that provides sufficient details to assess the content of your proposed presentation. If your abstract is accepted you will have the opportunity to re-submit an updated abstract.

Presentation Files

Video and audio clips should be embedded in your Power Point slides rather than linking to external files.

Presenters will take their Power Point slides to the conference on a memory stick, where an audiovisual technician will load your presentation.

All slides will be run from a central presentation computer. However, if you have a complex presentation, which includes multiple media files, we suggest you bring your own laptop as a backup in case of difficulties loading your presentation.

Presenters Registration

All presenters will be required to register for the symposium and pay the appropriate registration fee. Presenters also need to meet their own travel and accommodation costs.

Themes for 7th International Symposium on Soil Organic Matter

Ecological significance and function of SOM

SOM performs many ecosystem services in both natural and managed systems, yet mechanisms involved in its interaction with other biophysical processes such as nutrient cycling, water retention, structural stability remain difficult to fully elucidate. This session provides a forum in which research addressing these underlying questions, and the impacts they have on broader ecosystem processes can be presented.

Impacts of climate change and land use on SOM

Climate change may impact SOM directly through changed temperature and moisture regimes, and indirectly through changed vegetation assemblages or land management practices. This session aims to draw together new research on how SOM responds to these impacts, with a particular focus on potential tipping points where resistance to change may be overwhelmed.

The economic and social value of SOM

The fact that SOM delivers multiple ecosystem services is well known. However, there remains a dearth of quantitative information on the value of these services to land managers, agriculture, and broader society. This session aims to draw together information that elucidates the short- and long-term value of SOM, and the impacts of building or losing this resource.

SOM restoration: Restoring ecosystem function through SOM recovery

Remediation and restoration practices can often focus on the role of SOM in the success of these activities. This session presents an opportunity to share research that demonstrates the role that SOM plays in successful land remediation and restoration.

C sequestration – opportunities, costs, trade-offs

Soils are increasingly being looked to as a potentially important tool in our efforts to offset emissions and reduce our impacts on the global climate. However, such a concept is hotly contested. Here, the latest research assessing the opportunities and impacts of such strategies will be discussed.

SOM dynamics in fire-prone landscapes

Wildfires are an increasingly common phenomenon globally, and their impacts on SOM dynamics are poorly understood. This session provides an opportunity to present the latest research into both the response of SOM to fire, and also the role of black C in soils and ecosystems.

Going downunder: Deep SOM dynamics

Possibly seen as the last frontier, SOM in subsoils is far less studied than its surface counterparts. Here, we seek presentations that highlight recent advances in this area and which draw parallels with and highlight differences between processes in surface soils.

The living part of SOM – microbes, microfauna, mesofauna, macrofauna

Soils are the most complex ecosystem on the planet, and the biological component of them is hugely influential on SOM processes. Presentations are invited which describe the latest research in the field of soil biology and its interactions with SOM.

SOM, modelling, and data science

Simulation models describing SOM dynamics have been around for decades, and perform roles at levels ranging from the molecular and microbial scale through to global carbon accounts and climate predictions. Recent advances in computing capacity, data availability, and our understanding of biophyiscal processes have led to huge leaps forward in our capability to model across scales. Here, we provide opportunity for recent advances in modelling and data sciences associated with SOM research to be presented.

Organic resource management: the role of recycled “wastes”

As organic resource recovery and cycling increase across the globe, organic “wastes” such as biosolids, composts and digestates are increasingly being applied to soils. Here, we discuss the challenges and opportunities such resource streams pose, and how their interactions with soil differ from those of SOM.

The UN Sustainable Development Goals – The role of SOM

The UN SDGs form an accepted framework for sustainable global development. Effective management of SOM can contribute to several of these, and this session will explore the interface of cutting edge research into SOM and sustainable development policy

Rapid measurement techniques – pitfalls and advances

Recent advances in rapid spectral techniques coupled to modern chemometric analysis present huge opportunities to open up anlysis of SOM quantity and chemistry. However, their increasing accessibility also potentially leads to their mis-application beyond calibration datasets. This session will provide insight into the state-of-the-art of rapid techniques.

Stoichiometry – Does it matter?

Elemental stoichiometry has been a centrepiece of ecological theory for over 80 years, and forms a central part of many studies into SOM and the models that describe them. Here, we invite talks that explicitly explore relationships between nutrients and SOM processes.

Transport of SOM through landscapes

Desposition and loss of SOM through erosion and leaching processes can have significant impacts at the local, landscape, and global scale. Here, we seek presentations detailing the latest research into the movement of SOM at any or all of these scales.

High resolution analyses – where can they take us?

Over the past decades, the capabilities of instrumentation such as high-resolution MS and synchrotron-based techniques has increased rapidly. Here, we explore recent advances in our understandsing of SOM dynamics as facilitated by cutting edge instrumentation, and where the future may take us

Blue carbon

SOM doesn’t stop at the water’s edge. This session aims to showcase the latest research into the form, function, and impacts of management on SOM in aquatic and marine sediments
