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.

Effects of Grazing Season and Degradation Degree on the Soil Organic Carbon in Alpine Meadow
刘淑丽,林丽,张法伟,杜岩功,李以康,郭小伟,欧阳经政,曹广民 +7 more
TL;DR: This study investigates the effects of grazing season and degradation degree on soil organic carbon in alpine meadows. Results show that soil organic carbon decreases with depth and degradation, with varying trends between cold and warm seasons.

Response of Grazing Land Soil Health to Management Strategies: A Summary Review
TL;DR: In this paper, the authors provide a condensed review of studies on the response of three important soil properties related to soil health to grazing land management: water infiltration, carbon (C) sequestration, and nitrogen use efficiency.

TL;DR: The development of a functional soil is fundamental to restoring forest ecosystems following major disturbances such as surface mining as discussed by the authors, and practices for restoring water-related functions include avoiding compaction during soil reconstruction, creating rough surfaces to increase infiltration and reduce runoff and designing structures such as drainage swales to convey surface runoff to desired receiving areas with minimal damage.
Testing the environmental controls of microbial nitrogen-mining induced by semi-continuous labile carbon additions in the subarctic
TL;DR: In this paper , the authors investigated how N availability affects the priming of old soil organic matter (SOM) mineralization in subarctic soils by adding labile organic matter including 13C-glucose with and without mineral N, or 13Calanine, into soils with different N availabilities resulting from inorganic N and/or litter addition field-treatments.

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.
