Forest-to-Tea Conversion Intensifies Microbial Phosphorus Limitation and Enhances Oxidative Enzyme Pathways

Agronomy
Tea plantations are one of the most intensive land-use systems in subtropical China, but the long-term effects on soil microbial functioning remain insufficiently understood.

Experimental climate effect on seasonal variability of polyphenol/phenoloxidase interplay along a narrow fen-bog ecological gradient in Sphagnum fallax

, 2011
International audienceExtracellular phenoloxidase enzymes play an important role in the stability of soil carbon storage by contributing to the cycling of complex recalcitrant phenolic compounds.

Soil extracellular enzyme activities, soil carbon and nitrogen storage under nitrogen fertilization: A meta-analysis [PDF]

, 2016
Nitrogen (N) fertilization affects the rate of soil organic carbon (SOC) decomposition by regulating extracellular enzyme activities (EEA). Extracellular enzymes have not been represented in global biogeochemical models.

Cotton-Grass and Blueberry have Opposite Effect on Peat Characteristics and Nutrient Transformation in Peatland [PDF]

, 2017
Peatlands are large repositories of carbon (C). Sphagnum mosses play a key role in C sequestration, whereas the presence of vascular plants is generally thought to stimulate peat decomposition.

Soil Enzymes and Stable Isotopes as Suitable Soil–Plant Indicators of Ecosystem Functionality in Mediterranean Forests

Agronomy
Monitoring the soil–plant system in forest ecosystems is crucial for preserving their ecological functions and services. This study assessed carbon and nitrogen stable isotopes and ecoenzymatic stoichiometry as suitable indicators for characterizing the ...

Cascading regulation from soil microbial resource limitation to crop physiology by carbon-based materials for tobacco growth in continuous cropping obstacle soil

Industrial Crops and Products
Microbial resource limitation, as a risky obstacle in continuous cropping systems for sustainable production, can be relieved by carbon-based materials (CBMs).

Interpreting the differences in microbial carbon and nitrogen use efficiencies estimated by 18O labeling and ecoenzyme stoichiometry

Geoderma
Microbial carbon and nitrogen use efficiencies (CUE and NUE) are central to our understanding of soil C and N cycling. Although both the 18O-labeling approach and ecoenzyme stoichiometry model have been widely used to estimate microbial CUE and NUE ...
