Phosphorus cycling and adaptation of soil microbes to P availability

点击翻译按钮获取中文摘要

This project aims to determine how soil microbial communities adapt to phosphorus availability, and how the breakdown of microbial biomass sustains phosphorus demand. Using some of the most globally P-impoverished soils, the project expects to uncover how cellular composition of microbial populations is shaped by phosphorus availability, and feedbacks between cellular composition of microbes and phosphorus availability. Expected outcomes include better understanding of factors determining phosphorus availability, and a new analytical toolkit for tracing pools and fluxes of organic P in soils. Overall, these should provide significant benefit to the global effort in understanding how phosphorus shapes soil function.
