Carbon:Nitrogen:Phosphorus Stoichiometry in Fungi: A Meta-Analysis. [PDF]

Front Microbiol, 2017
: Surveys of carbon:nitrogen:phosphorus ratios are available now for major groups of biota and for various aquatic and terrestrial biomes. However, while fungi play an important role in nutrient cycling in ecosystems, relatively little is known about ...

Topography modulates effects of nitrogen deposition on microbial resource limitation in a nitrogen-saturated subtropical forest

Forest Ecosystems, 2021
Background Nitrogen (N) saturation theory proposes that an ecosystem might switch from N limitation to carbon (C), phosphorus (P), or other nutrient limitations if it receives continuous N input.

Eco-enzymatic stoichiometry and microbial non-homeostatic regulation depend on relative resource availability during litter decomposition

Ecological Indicators, 2022
The relationships between soil eco-enzymatic stoichiometry and substrate stoichiometry could be used to explain nutrient cycling processes regulated by microbial biomass stoichiometry. But what are the relationships between the stoichiometry of resources,

Responses of Microbial Nutrient Acquisition to Depth of Tillage and Incorporation of Straw in a Chinese Mollisol

Frontiers in Environmental Science, 2021
Tillage and straw incorporation are important agricultural practices that can break the plow layer and improve Mollisol fertility. The effect of these practices on the limitation of resources for soil microorganisms, however, is unclear. We established a

Ecoenzymes as Indicators of Compost to Suppress Rhizoctonia solani [PDF]

, 2017
Reports of disease suppression by compost are inconsistent likely because there are no established standards for feedstock material, maturity age for application, and application rate.

Effects of soil organic matter properties and microbial community composition on enzyme activities in cryoturbated arctic soils [PDF]

, 2014
Enzyme-mediated decomposition of soil organic matter (SOM) is controlled, amongst other factors, by organic matter properties and by the microbial decomposer community present.

Extracellular enzyme activity in the mycorrhizospheres of a boreal fire chronosequence [PDF]

, 2012
Saprotrophic microbes are typically credited with producing extracellular enzymes that recycle organic matter, though roots and mycorrhizal fungi also can contribute and may compete with the saprotrophs.

Chronic nitrogen fertilization and carbon sequestration in grassland soils: evidence of a microbial enzyme link [PDF]

, 2015
Chronic nitrogen (N) fertilization can greatly affect soil carbon (C) sequestration by altering biochemical interactions between plant detritus and soil microbes.

Land conversion from cropland to grassland alleviates climate warming effects on nutrient limitation: Evidence from soil enzymatic activity and stoichiometry

Global Ecology and Conservation, 2020
Climate warming and land conversion are key factors affecting ecosystem functions. Investigating the effects of these two factors on soil enzyme activity and stoichiometry will provide insights into soil nutrient limitation in terrestrial ecosystems ...
