Intensively fertilized acidic soils are global hotspots of nitrous oxide (NO) emissions, contributing to net agronomic greenhouse gas outcomes. Identifying the key drivers of soil NO emissions is hampered by the synergistic or antagonistic effects of multiple factors. Within a framework based on the predominant role of microbial communities producing NO, the NO emissions are affected either by proximal

Plants and soil microbes are often challenged by multiple global change factors (GCFs), and their responses to single GCFs may differ from those to multiple GCFs due to synergistic or antagonistic interactions. Therefore, changes in number of GCFs may alter plant-soil feedbacks. We conditioned a soil by growing a plant of in the soil for three months, and then grew a plant of the same species in a

Input of high-quality litter reduces soil carbon losses due to priming in a subtropical pine forest Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-04-22 Shiting Li, Maokui Lyu, Cui Deng, Wei Deng, Xiaohong Wang, Anne Cao, Yongmeng Jiang, Jueling Liu, Yuming Lu, Jinsheng Xie
To date, it is unclear how differences in litter quality affect soil organic matter (SOM) decomposition through a phenomenon called 'priming effects' (PEs), especially for low-fertility forest soils under field conditions. Here, the effects of low- and high-quality leaf litter on PE and microbial metabolism of litter-derived carbon (C) were explored in a low-fertility pine () plantation. A 185-day

Earthworms can compact the soil through the production of casts and by pushing the soil when burrowing. However, how different ecological categories differently affect these processes is poorly known. This study aimed to expand our knowledge on the compaction within the drilosphere and to examine similarities and differences between ecological categories. We sampled 21 earthworm species in Vietnam

Soil total nitrogen (STN) content is one of the most important factors limiting soil function in terrestrial ecosystems. One of the most important roles of microbial diversity is to provide tools to boost N mineralization making N available for plants and microbes. However, how STN content interacts with microbial diversity in explaining soil function remains virtually unknown. Here, we combined two

Warming persistently stimulates respiration from an arable soil over a decade, regardless of reduced summer precipitation Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-04-15 Vinzent Leyrer, Christian Poll, Johannes Wirsching, Ellen Kandeler, Sven Marhan
Climate change factors alter soil microbial biomass and respiration, which represent two key parameters of carbon (C) cycling in soils. While these interrelations are increasingly well described for soils in natural ecosystems, long-term studies conducted in temperate agricultural ecosystems do rarely exist. Here we used the ‘Hohenheim Climate Change Experiment (HoCC)’ to describe the response of microbial

Preferential adsorption of nitrogen- and phosphorus-containing organic compounds to minerals in soils: A review Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-04-13 Marie Spohn
There is growing evidence that many nitrogen- and phosphorus-containing organic compounds in soils have on average a higher affinity for adsorption to mineral surfaces than nutrient-free organic compounds.

Hungate, Jeffrey Kimbrel, Jose Liquet, Marissa Lafler, Maxwell Marple, Peter S. Nico, Ljiljana Paša-Tolić, Eric Slessarev, Jennifer Pett-Ridge
Soil microorganisms help transform plant inputs into mineral-associated soil organic carbon (SOC) – the largest and slowest-cycling pool of organic carbon on land. However, the microbial traits that influence this process are widely debated. While current theory and biogeochemical models have settled on carbon-use efficiency (CUE) and growth rate as positive predictors of mineral-associated SOC, empirical
