Drought-resistant fungi control soil organic matter decomposition and its response to temperature
Microbial-mediated decomposition of soil organic matter (SOM) ultimately makes a considerable contribution to soil respiration, which is typically the main source of CO2 arising from terrestrial ecosystems. Despite this central role in the decomposition of SOM, few studies have been conducted on how climate change may affect the soil microbial community and, furthermore, on how possible climate...
متن کاملRevisiting the hypothesis that fungal-to-bacterial dominance characterizes turnover of soil organic matter and nutrients
Resolving fungal and bacterial groups within the microbial decomposer community is thought to capture disparate life strategies for soil microbial decomposers, associating bacteria with an r-selected strategy for carbon (C) and nutrient use, and fungi with a K-selected strategy. Additionally, food-web model-based work has established a widely held belief that the bacterial decomposer pathway in...
متن کاملEffect of Living Roots on Soil Organic Matter Decomposition
Published information is contradictory about the inhibitory or stimulatory effect of living roots on soil organic matter d~m~sition. In this study, i4C-labelled rye straw was exposed in fertilii or unfertilized soil with or without plants (winter rye, Se&e cereuIe) for 49 days under semi-controlled conditions. Our objective was to study the effect of roots on soil organic matter mineralization ...
متن کاملNitrogen addition changes grassland soil organic matter decomposition
Humans have dramatically increased the deposition and availability of nutrients, such as nitrogen (N), worldwide. Soil organic matter (SOM) is a significant global reservoir of carbon (C); however, the effects of N enrichment on this large, heterogeneous C stock are unclear. Nitrogen has variable effects on the biological, chemical, and physical factors that determine SOM pool mean residence ti...
متن کاملSulfur species behavior in soil organic matter 3 during decomposition
7 [1] Soil organic matter (SOM) is a primary reservoir of terrestrial sulfur (S), but its role in 8 the global S cycle remains poorly understood. We examine S speciation by X-ray 9 absorption near-edge structure (XANES) spectroscopy to describe S species behavior 10 during SOM decomposition. Sulfur species in SOM were best represented by organic 11 sulfide, sulfoxide, sulfonate, and sulfate. Th...
