GEODERMA

Title:  SOM: From structure to functions
Guest Editors:  Sandra Spielvogel,  Michaela Dippold,  Bin Zhang, Bruce HungateYakov Kuzyakov

Submission deadline: December 31, 2015

Soils are the most heterogeneous part of the biosphere containing approximately 2000 billion tons of organic carbon (C). This huge terrestrial C sink as well as spatial variability of properties and processes secure long term stability of soils and their functions. To better predict soil organic matter (SOM) storage, turnover and functions, but also to safeguard the productivity of soils as a natural resource, a comprehensive understanding of SOM origin, structure and transformation mechanisms is necessary. Novel methods and approaches focusing on stabilization-destabilization processes and interactions between various SOM pools are of particular importance to understand SOM stability and vulnerability in natural and agricultural ecosystems.

This special issue welcomes contributions to (1) cutting edge methods and techniques to characterize the nature of organic matter and its sequestration in soils, (2) mechanisms of SOM stabilization and destabilization, (3) protection and restoration of soil health, fertility and crop productivity, (4) novel combined empirical and modelling approaches to deepen our understanding of SOM functioning, with a special focus on hotspots of SOM transformations, as well as (6) innovative concepts evaluating the terrestrial SOM cycling balance and its interlinkage with other ecosystem compartments.

In summary, this special issue aims to link structure with functions of SOM and to include transformation processes into state-of-the-art SOM modelling approaches over a broad range of spatial and temporal scales.                                

 

EUROPEAN JOURNAL of SOIL BIOLOGY

Title:  Biotic drivers of SOM turnover
Guest Editors:  Evgenia Blagodatskaya,  Christoph Tebbe,  Yakov Kuzyakov

Submission deadline: January 1, 2016

Biota: plants and microorganisms – drives biogeochemical cycles, including the turnover of soil organic matter (SOM). Input of organics by plants to the soil, redistribution of allocated carbon (C) by animals and roots within soil profile, and utilization and mineralization by microorganisms circulate organic C on time scale from seconds to millennia. Many questions of input and localization of organics by roots into soil, initial transformation of the labile input and production of stabilized microbial compounds, as well as their mineralization remain unclear.

This Special Issue ‘Biotic drivers of SOM turnover’ analyzes the contribution of plants, microorganisms and animals to input, stabilization, mineralization and redistribution of organics in soil, with focus on microbial hotspots: detritusphere, rhizosphere, biopores and aggregate surfaces. Especially the interactions between and within the biotic drivers, and consequences for microbial community structure and functions are of interest. Considering the sensitivity of biota to environmental conditions, to their variability and extremes, studies on the effects of climate change on SOM transformations mediated by biotic drivers are very welcome. We also encourage contributions of modellers considering the biota as the main driver of SOM turnover and upscaling results of mechanistic studies on large scales.

Title: Root-Soil-Microbial and Carbon-Nutrient Interactions

Guest Editors: Johanna Pausch, Daniel Rasse, Xingliang Xu, Yakov Kuzyakov

Submission deadline: January 1, 2016

Rhizodeposition – the input of organics by living roots to soil – is a key driver of microbially mediated processes in soil and hence, a major link between above- and belowground processes. Root exudates as carbon and energy source for microorganisms affect their activity and consequently change soil organic matter (SOM) turnover and nutrient cycling in soils.

The Special Issue “Root-Soil- Microbial and Carbon-Nutrient Interactions” is focused on the mechanistic understanding of processes, by which root-derived C govern SOM and nutrient turnover in soil.

 

We are looking for innovative approaches and new insights into C pools and fluxes influenced by rhizosphere processes, biochemical characteristics of rhizosphere, and exchange of C and nutrients between plants, microorganisms and soil compartments. Special emphasis is placed on the connection of rhizosphere processes with substrate availability, nutrient availability, microbial community structure and activity.
