AbstractMicrobial metabolism directly participates in soil nutrient recycling and ecosystem stability. Although the rhizosphere soil is one of the most active habitats, information on how microorganisms acquire nutrients based on ecoenzymatic stoichiometry is lacking, especially for major food crops under field conditions.

Afforestation has significantly affected interactions between soil nutrients and microbial enzymes. To understand the detailed variations in extracellular enzyme activity and their link with soil nutrient availability after returning farmland (FL) to forest, soil samples were collected from FL and three afforested lands, Robinia pseudoacacia L. forest (

Science of The Total Environment, 2023
Soil arthropods are crucial decomposers of litter at both global and local scales, yet their functional roles in mediating microbial activity during litter decomposition remain poorly understood. Here, we conducted a two-year field experiment using litterbags to assess the effects of soil arthropods on the extracellular enzyme activities (EEAs) in two ...

Journal of the Science of Food and Agriculture, 2021
AbstractBACKGROUNDSoil‐ and plant‐produced extracellular enzymes drive nutrient cycling in soils and are assumed to regulate supply and demand for carbon (C) and nutrients within the soil. Thus, agriculture management decisions that alter the balance of plant and supplemental nutrients should directly alter extracellular enzyme activities (EEAs), and ...

The flow of carbon and nutrients from plant production into detrital food webs is mediated by microbial enzymes released into the environment (ecoenzymes). Ecoenzymatic activities are linked to both microbial metabolism and environmental resource availability.

The presence and interaction of shrubs and arbuscular mycorrhizal fungi (AMF) are important for the biogeochemical cycles and sustainable development of arid and semiarid ecosystems. The regulatory mechanisms of the soil microenvironment were explored by studying microbial nutrient constraints in ecosystems.

Ecoenzymatic stoichiometry at the extremes: How microbes cope in an ultra-oligotrophic desert soil
Soil Biology and Biochemistry, 2015Abstract Arid ecosystems are characterized by stressful conditions of low energy and nutrient availability for soil microorganisms. It has been observed that the ecoenzymes needed for the transformation of organic compounds into assimilable products show similar scaling relationships in different habitats (logarithmic C:N:P scaling ratios ∼1:1:1). In

Variation in soil microbial metabolism remains highly uncertain in predicting soil carbon (C) sequestration, and is particularly and poorly understood in agroecosystem with high soil phosphorus (P) variability. This study quantified metabolic limitation of microbes and their association with carbon use efficiency (CUE) via extracellular enzymatic ...

Abstract To evaluate whether microbial stoichiometries of biomass and enzyme activity could vary in response to changes in nutrient availability in an arable soil during the crop growth period, temporal variation in nutrient availability, soil enzyme activities associated with carbon (C), nitrogen (N), phosphorus (P), and sulfur (S) acquisition, and ...

AbstractSoil ecoenzymatic stoichiometry reflects the nutrient flow of ecosystems. While knowledge exists on how the secondary succession of plants affects soil physicochemical properties and soil ecoenzymatic activity, less is known about how soil ecoenzymatics change during this process.
