Soil is an extremely complex and dynamic matrix, in part, due to the wide diversity of organisms living within it. Soil organic matter (SOM) is the fundamental substrate on which the delivery of ecosystem services depends, providing the metabolic fuel to drive soil function. As such, studying the soil metabolome (the diversity and concentration of low molecular weight metabolites), as a subset of SOM

Nitrification-induced acidity controls CO2 emission from soil carbonates Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-03-11 Jingjing Tao, Lichao Fan, Jianbin Zhou, Callum Colin Banfield, Yakov Kuzyakov, Kazem Zamanian
Nitrification acidifies soil, and the produced H are neutralized by inorganic carbon (C) in soil leading to irreversible CO emissions. CO released by nitrogen (N) fertilizer-induced acidification is partitioned between solid (CaCO re-precipitation), liquid (dissolved HCO and CO) and gaseous (CO) phases. Therefore, quantifying the effects of N fertilization on CO emissions from soil inorganic C is an

From rhizosphere to detritusphere – Soil structure formation driven by plant roots and the interactions with soil biota Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-03-09 Carsten W. Mueller, Vera Baumert, Andrea Carminati, Amandine Germon, Maire Holz, Ingrid Kögel-Knabner, Stephan Peth, Steffen Schlüter, Daniel Uteau, Doris Vetterlein, Pedro Teixeira, Alix Vidal
Roots and the associated soil directly affected by root activity, termed the rhizosphere, have both been extensively studied and recognized for their crucial role in soil functioning. The formation of the rhizosphere is primarily driven by the effect of roots on shaping the physical structure of the soil, which in turn has direct feedbacks on the interactions between physical, biological and chemical

Soil in high latitude and altitude cold regions contains over half of soil organic carbon (SOC) globally, so the decomposition of these SOCs under climate warming could release huge amounts of carbon dioxide to the atmosphere, amplifying climate warming. However, it is still unclear how the SOC storages will change when the ecosystem reaches the final and stable stage (i.e., the climax) under long-term

Dissolved organic matter (DOM) is a small but very reactive pool of organic matter (OM) in the environment. Its role is related to its composition, which depends on its source. In soils, vegetation is the main source of DOM, and biodegradation is the main regulating mechanism. This study aims to characterise DOM produced by contrasted arctic vegetation species and their biodegradation products.

Soil organic carbon (SOC) is the largest terrestrial carbon (C) pool and is vulnerable to climate and land-use changes. Promoting the stabilization of SOC will reduce climate change-induced C losses. Mineral-associated organic carbon (MAOC), formed by the association of organic carbon with silt- and clay-sized minerals, is the major stabilized SOC fraction and key to sustaining soil health and mitigating

Deep soils (defined here as soil layers >1 m beneath the ground) contain a significant amount of soil organic carbon (SOC) with a relatively slow turnover rate. In oxygen (O) limit conditions, terms here as “micro-aerobic environment”, a high concentration of phenol usually suppresses SOC decomposition by inhibiting hydrolase activities, a mechanism known as the ‘enzyme latch’. Here, we showed that

Microbial nutrient limitation along a 2-million-year dune chronosequence Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-03-04 Benjamin L. Turner, Hans Lambers, Zhihui Wen, Yasha-Maria Auer, Ellen Kandeler
Long-term ecosystem development is characterized by a switch from nitrogen (N) to phosphorus (P) limitation of plant communities as soils age, which leads to changes in plant biomass, diversity, and foliar nutrient concentrations. Similar effects occur belowground, although the extent to which nutrient availability is the primary driver of long-term changes in soil microbial communities remains uncertain

Deadwood heterogeneity is regarded as a primary causal driver of deadwood-associated soil biodiversity, but the underlying mechanisms remain elusive. This is partly due to the technical difficulties in disentangling and quantifying different components (e.g., deadwood is both habitat and food) of heterogeneity to which soil organisms may have context-dependent responses. Furthermore, non-trophic interactions

Alternate wetting-drying (AWD) in rice cultivation controls soil redox conditions and consequently nutrient solubility. Under low redox potential, ferric iron reduction leads to bound phosphate (Fe(III)–P) dissolution, but lack of oxygen retards organic phosphorus (P) mineralization. Microorganisms accelerate P mineralization as the redox potential increases during drying, but it is not known which

As one of the most important drivers of global climate change, land use change (LUC) has markedly altered the regional and global carbon (C) cycles. However, the geographic variations and the key drivers in the effects of LUC on temperature sensitivity () of soil microbial respiration () are still not fully elucidated, hence impeding the spatially explicit predictions of soil C cycling under climate

Soil carbon mineralization and microbial community dynamics in response to pyrogenic organic matter addition Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-01-27 Nayela Zeba, Timothy D. Berry, Monika S. Fischer, Matthew F. Traxler, Thea Whitman
Wildfires can either negatively impact soil carbon (C) stocks through combustion or increase soil carbon stocks through the production of pyrogenic organic matter (PyOM), which is highly persistent and can affect non-pyrogenic soil organic carbon (SOC) mineralization rates. In this study, we used fine-resolution CO flux tracing to investigate PyOM-C mineralization, soil priming effects, and their impacts

Altered litter stoichiometry drives energy dynamics of food webs through changing multiple facets of soil biodiversity Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-01-24 Bingbing Wan, Andrew D. Barnes, Anton Potapov, Jiani Yang, Mengyi Zhu, Xiaoyun Chen, Feng Hu, Manqiang Liu
Global change in organismal stoichiometry and biodiversity is often correlated with energy dynamics in ecological networks that underpin the functioning of terrestrial ecosystems and services. However, we know little about which facets of biodiversity, such as taxonomic, functional, and phylogenetic diversity, account for most of the variation in the energy dynamics of ecological networks along litter

Stabilized microbial necromass in soil is more strongly coupled with microbial diversity than the bioavailability of plant inputs Soil Biol. Biochem. (IF 9.7) Pub Date : 2024-01-19 Gerrit Angst, Šárka Angst, Jan Frouz, Stanislav Jabinski, Veronika Jílková, Jaroslav Kukla, Mengmeng Li, Travis B. Meador, Roey Angel
Microbial necromass carbon (C) can substantially contribute to stabilized soil organic matter (SOM), and effective management of this C may help mitigate climate change. However, factors important to the formation of microbial necromass are only partly understood. While bioavailable plant inputs may induce necromass formation by boosting microbial growth and C use efficiency, other microbial traits
