abstract = {In this review, we introduce microbially-mediated soil
processes, players, their functional traits, and their links
to processes at biogeochemical interfaces [e.g.,
rhizosphere, detritusphere, (bio)-pores, and aggregate
surfaces]. A conceptual view emphasizes the central role of
the rhizosphere in interactions with other biogeochemical
interfaces, considering biotic and abiotic dynamic drivers.
We discuss the applicability of three groups of traits based
on microbial physiology, activity state, and genomic
functional traits to reflect microbial growth in soil. The
sensitivity and credibility of modern molecular approaches
to estimate microbial-specific growth rates require further
development. A link between functional traits determined by
physiological (e.g., respiration, biomarkers) and genomic
(e.g., genome size, number of ribosomal gene copies per
genome, expression of catabolic versus biosynthetic genes)
approaches is strongly affected by environmental conditions
such as carbon, nutrient availability, and ecosystem type.
Therefore, we address the role of soil physico-chemical
conditions and trophic interactions as drivers of
microbially-mediated soil processes at relevant scales for
process localization. The strengths and weaknesses of
current approaches (destructive, non-destructive, and
predictive) for assessing process localization and the
corresponding estimates of process rates are linked to the
challenges for modeling microbially-mediated processes in
heterogeneous soil microhabitats. Finally, we introduce a
conceptual self-regulatory mechanism based on the flexible
structure of active microbial communities. Microbial taxa
best suited to each successional stage of substrate
decomposition become dominant and alter the community
structure. The rates of decomposition of organic compounds,
therefore, are dependent on the functional traits of
dominant taxa and microbial strategies, which are selected
and driven by the local environment.},
