TL;DR: In this article, a negative relationship between primary production and soil carbon (C) content is found, and the authors conclude that energy available to soil microbes and microbial competition are important determinants of soil C decomposition.

Abstract: It is commonly predicted that the intensity of primary production and soil carbon (C) content are positively linked. Paradoxically, many long-term field observations show that although plant litter is incorporated to soil in large quantities, soil C content does not necessarily increase. These results suggest that a negative relationship between C input and soil C conservation exists. Here, we demonstrate in controlled conditions that the supply of fresh C may accelerate the decomposition of soil C and induce a negative C balance. We show that soil C losses increase when soil microbes are nutrient limited. Results highlight the need for a better understanding of microbial mechanisms involved in the complex relationship between C input and soil C sequestration. We conclude that energy available to soil microbes and microbial competition are important determinants of soil C decomposition.

Plant Community and Nitrogen Deposition as Drivers of Alpha and Beta Diversities of Prokaryotes in Reconstructed Oil Sand Soils and Natural Boreal Forest Soils
TL;DR: Nitrogen deposition, pH, and plant species were the main factors influencing the β-diversity of the prokaryotic communities in natural and reconstructed soils, and this study improved the understanding of how vegetation, soil characteristics and microbial communities interact and drive soil functions.

TL;DR: Plant-soil synchrony in nutrient cycles is essential for sustainable agrosystems. It emerges from plant-soil and plant-plant interactions, eco-physiological processes, soil physicochemical processes, and the dynamics of various nutrient reservoirs.

An extraction method for measuring soil microbial biomass c
TL;DR: In this paper, the effects of fumigation on organic C extractable by 0.5 m K2SO4 were examined in a contrasting range of soils and it was shown that both ATP and organic C rendered decomposable by CHCl3 came from the soil microbial biomass.

The priming effect of organic matter: a question of microbial competition
TL;DR: In this paper, the authors build a conceptual model of the priming effect based on the contradictory results available in the literature adopting the concept of nutritional competition, and they postulate that priming results from the competition for energy and nutrient acquisition between the microorganisms specialized in the decomposition of fresh organic matter and those feeding on polymerised SOM.
