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).

Soil microbial biomass and function are altered by 12 years of crop rotation [PDF]

SOIL, 2016
Declines in plant diversity will likely reduce soil microbial biomass, alter microbial functions, and threaten the provisioning of soil ecosystem services.

Mineralization of nutrients from soil microbial biomass

Mineralization of nutrients from soil microbial biomass, 1982
Soil samples of parabrown earth and chernozem, each having a different amount of microbial biomass, were used to investigate the contribution of microbial cells to the pool of mobile plant nutrients in soils. The quantities of nutrients mobilized in soils which had been dried or fumigated were closely related to the quantities available in freshly ...

RESPONSE OF SOIL MICROBIAL BIOMASS TO CeO2 NANOPARTICLES

EQA, 2011
But de ce travail a été d'évaluer l'impact d'une exposition chronique de nanoparticules de CeO2 (NP diamètre compris entre 50 et 150 nm), sur la biomasse microbienne du sol. L'évaluation de l'effet qui peuvent avoir sur la qualité du sol a été expérimentée sur horizons A1 et A2 d'Epileptic Cambisols en utilisant concentrations de 100 ppm avec des ...

Short-term winter snow reduction stimulates soil nutrient leaching without changing the microbial biomass in an alpine fir forest

Global Ecology and Conservation, 2021
Winter snowpack maintains a relatively warm environment for soil microorganisms and modulates soil biogeochemical cycles in cold ecosystems; however, snowpack reduction induced by climate warming may change soil dissolved nutrient leaching and microbial ...
