Microbial physiology and necromass regulate agricultural soil carbon accumulation [PDF]

Soil Biology and Biochemistry, 2015
Abstract Strategies for mitigating soil organic carbon (SOC) losses in intensively managed agricultural systems typically draw from traditional concepts of soil organic matter formation, and thus emphasize increasing C inputs, especially from slowly decomposing crop residues, and reducing soil disturbance.

Topographic and Climatic Determinants of Soil Organic Carbon Across Landscapes: A Meta‐Analysis

Land Degradation &Development, EarlyView.
ABSTRACT The soil is the greatest natural store of organic carbon, holding between 1500 to 1550 Pg C of organic carbon at the top 100 cm of the soil globally—roughly twice the carbon pool in the atmosphere. The spatial distribution of this stock is controlled by a complex chain of controls: topographic position regulates the hydrological redistribution,

Higher NO3−‐N Levels Under Mulberry (Morus alba L.) Planting Enhanced CAZyme Abundance, Increasing Soil Carbon Stability

Land Degradation &Development, EarlyView.
ABSTRACT Afforestation is widely advocated for boosting carbon (C) sequestration. However, the stability of soil C pools in economically and culturally significant mulberry plantations remains poorly understood. The soil organic C (SOC) contents in different aggregates and the oxidizable OC fractions were measured.

Straw return combined with water-saving irrigation increases microbial necromass accumulation by accelerating microbial growth-turnover in Mollisols of paddy fields

Geoderma
Soil microorganisms are key to the flow of carbon through soils. As the most carbon-rich soils, Mollisols are very sensitive to disturbance and more prone to be carbon sources than carbon sinks. To understand how the microbial physiology [i.e., microbial

Optimized Fertilization Balances Microbial Carbon and Nitrogen Use Efficiency: Evidence From Microbial Communities

Land Degradation &Development, EarlyView.
ABSTRACT Optimized fertilization involving reduced mineral N input and organic substitution can alter resource stoichiometry, microbial carbon use efficiency (CUE) and nitrogen use efficiency (NUE). However, how fertilization‐induced resource imbalance reshapes microbial community to regulate CUE and NUE remains unclear. We conducted a field experiment

From foraging to decomposition: Large vertebrates as biotic drivers of trace element cycling across landscapes

Journal of Animal Ecology, EarlyView.
We highlight an overlooked pathway in ecosystem functioning: the role of animal carcass decomposition in trace element cycling. By linking animal life cycles to landscape‐scale processes, we explain how large animals redistribute scarce elements and influence spatial heterogeneity, with implications for ecosystem functioning and restoration.

Experimental and genomic evidence clarifies the mycorrhizal helper role of a widespread bacterium in Bishop pine forests

New Phytologist, EarlyView.
Hypothetical model of Paraburkholderia–EcMF–Bishop pine interactions. Summary Whether a widespread bacterial strain of Paraburkholderia can enhance the physiological responses of ectomycorrhizal fungi (EcMF) and host Bishop pine seedling growth remains unclear. We developed a ‘top‐down meets bottom‐up’ approach that harmonized data from molecular field

Dataset for the global change effects on microbial necromass content in soil

, 2023
The impacts of global changes (nutrient addition, warming,  elevated atmospheric carbon dioxide , and drought) on microbial necromass are poorly understood despite its critical role in the cycling and sequestration of soil carbon (C) and nutrients. Here,

Contrasting influences of ectomycorrhizal fungi on decomposition depending on soil fertility

New Phytologist, EarlyView.
Ecosystem types along a gradient of increasing nutritional and climatic constraints with an overall transition from carbon (C)to nitrogen (N) limitation on decomposition. Summary Despite their dominance in many terrestrial ecosystems, the impact of ectomycorrhizal fungi on organic matter decomposition is notably variable across different ecological ...

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

New Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.
