Effects of tea planting age on soil microbial biomass C:N:P stoichiometry and microbial quotient

Plant, Soil and Environment, 2023
This study aimed to determine the effect of tea planting age on stoichiometric ratios of microbial biomass carbon (MBC), nitrogen (MBN), and phosphorus (MBP) and soil microbial quotient (SMQ, expressed as qMBC, qMBN, and qMBP, respectively).

Temperature legacies predict microbial metabolic quotient across forest biomes

Global Ecology and Biogeography, 2022
AbstractAimPalaeoclimate legacies have been reported to influence microbial communities and carbon (C) stocks even after thousands of years. However, the direct and indirect influences of climate legacies on microbial C processes remain poorly understood and thus limit our capacity to predict how climate legacies regulate C cycling.

Drivers of the microbial metabolic quotient across global grasslands

Global Ecology and Biogeography, 2023
AbstractAimThe microbial metabolic quotient (MMQ; mg CO2‐C/mg MBC/h), defined as the amount of microbial CO2 respired (MR; mg CO2‐C/kg soil/h) per unit of microbial biomass C (MBC; mg C/kg soil), is a key parameter for understanding the microbial regulation of the carbon (C) cycle, including soil C sequestration.

Evaluating composted sewage sludge as a phosphorus fertilizer in wheat grown on soils with different properties. [PDF]

J Environ Qual
Abstract Urbanization generates significant amounts of sewage sludge (SS), with relatively high concentrations of plant nutrients such as phosphorus (P). When biochemically stabilized by composting, SS (composted sewage sludge [CSW]) can serve as a sustainable P source in agriculture, supporting a circular economy and reducing agriculture's dependence ...

The stoichiometry of soil microbial biomass determines metabolic quotient of nitrogen mineralization

Environmental Research Letters, 2020
Abstract Soil nitrogen (N) mineralization is crucial for the sustainability of available soil N and hence ecosystem productivity and functioning. Metabolic quotient of N mineralization (Q min), which is defined as net soil N mineralization per unit of soil microbial biomass N, reflects the efficiency of soil N ...
