Phosphorus in the soil microbial biomass
Soil Biology and Biochemistry, 1984 Phosphorus in the soil microbial biomass (biomass P) and soil biomass carbon (biomass C) were linearly related in 15 soils (8 grassland, 6 arable, 1 deciduous woodland), with a mean P concentration of 3.3% in the soil biomass. The regression accounted for 82% of the variance in the data.

Representation of Dormant and Active Microbial Dynamics for Ecosystem Modeling [PDF]
, 2013 Dormancy is an essential strategy for microorganisms to cope with environmental stress. However, global ecosystem models typically ignore microbial dormancy, resulting in major model uncertainties.

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).
