Understanding how plant species influence soil nutrient cycling is a major theme in terrestrial ecosystem ecology. However, the prevailing paradigm has mostly focused on litter decomposition, while rhizosphere effects organic matter (SOM) decomposition have attracted little attention. Using dual 13 C/15 N labeling approach 'common garden' glasshouse experiment, we investigated economic strategies of 12 grassland (graminoids, forbs and legumes) drive nitrogen (N) via processes, this turn affects acquisition growth. Acquisitive with higher photosynthesis, carbon rhizodeposition uptake than conservative induced stronger acceleration through priming SOM decomposition. This allowed them to take up larger amounts allocate it above ground promote thereby sustaining their faster The N2 -fixation ability legumes enhanced by promoting photosynthesis rhizodeposition. Our study demonstrates that regulate plant-soil carbon-nitrogen feedback operating rhizosphere. These findings provide novel mechanistic insights into contrasting sustain nutrition growth regulating nutrients microbes

Abstract The role of soil fauna in crucial ecosystem services such as nutrient cycling remains poorly quantified, mainly because the overly reductionistic approach adopted most experimental studies. Given that increasing nitrogen inputs various ecosystems influence structure and functioning microbes activity fauna, we aimed to quantify entire nematode community mineralization an set-up emulating nutrient-rich field conditions accounting for interactions amongst microbial communities plants. To this end, reconstructed a complex foodweb mesocosms comprised largely undisturbed native microflora added into defaunated soil, planted with Lolium perenne model plant, amended fresh grass-clover residues. We determined N P availability plant uptake, biomass abundance during three-month incubation. presence nematodes significantly increased production (+9%), net (+25%) (+23%) compared their absence, demonstrating link below- above-ground processes, primarily through availability. presented allows realistically provided by biota.

Abstract. Soil organic matter (OM) represents a key C pool for climate regulation but also an essential component soil functions and services. Scientific research in the 21st century has considerably improved our knowledge of its dynamics, particularly under pressure global disruption carbon cycle. This paper reviews processes that control dynamics soil, representation these over time, their dependence on variations major biotic abiotic factors. The most recent advanced gained includes following. (1) Most is composed small molecules, derived from living organisms, without transformation via additional polymerization; (2) microbial compounds are predominant long term; (3) primary belowground production contributes more to than aboveground inputs; (4) contribution less biodegradable low (5) two factors determine “yield” initial substrates: yield used by microorganisms association with minerals, poorly crystalline which stabilize compounds; (6) interactions between plants regulate turnover time therefore stocks; (7) among only few considered current modeling approaches (i.e., temperature, water content, pH, particle size, sometimes N interactions); (8) although models assume involved linear, there now many indications nonlinear linked OM (e.g., priming). Farming practices, therefore, affect stocks not through inputs effect organomineral interactions, yet it still been possible properly identify main mechanisms loss (or gain). Greater insight into interdependencies, hierarchy sensitivity agricultural practices could provide future levers action sequestration soil.

Theoretical and empirical advances have revealed the importance of biodiversity for stabilizing ecosystem functions through time. Despite global degradation soils, whether loss soil microbial diversity can destabilize functioning is poorly understood. Here, we experimentally quantified contribution fungal bacterial communities to temporal stability four key related biogeochemical cycling. Microbial enhanced all this pattern was particularly strong in plant-soil mesocosms with reduced richness where over 50% taxa were lost. The effect linked asynchrony among whereby different fungi bacteria promoted at times. Our results emphasize need conserve provisioning multiple that soils provide society.

Abstract Trophic interactions are crucial for carbon cycling in food webs. Traditionally, eukaryotic micropredators considered the major of bacteria soils, although like myxobacteria and Bdellovibrio also known bacterivores. Until recently, it was impossible to assess abundance prokaryotes eukaryotes soil webs simultaneously. Using metatranscriptomic three-domain community profiling we identified pro- 11 European mineral organic soils from different climes. Myxobacteria comprised 1.5–9.7% all obtained SSU rRNA transcripts more than 60% potential bacterivores most soils. The name-giving well-characterized predatory affiliated with Myxococcaceae were barely present, while Haliangiaceae Polyangiaceae dominated. In predation assays, representatives latter showed prey spectra as broad Myxococcaceae. 18S micropredators, amoeba nematodes, generally less abundant myxobacterial 16S transcripts, especially Although does not directly reflect organismic abundance, our findings indicate that could be keystone taxa microbial web, impact on prokaryotic composition. Further, they suggest an overlooked, yet ecologically relevant web module, independent subject separate environmental evolutionary pressures.
