Author
Summary
This article discusses how excessive rainfall and saturated soils affect microbial communities and plant health. It explains that while all microbes rely on water films in soil, flooding displaces oxygen, which is essential for both certain microbes and plant root respiration. The article explores the shift in microbial populations under waterlogged conditions, focusing on obligate anaerobes and the challenges faced by plants and aerobic microorganisms.

· 4 pulledWhile all microbes live on water films in the soil, too much water changes the microbial community.
Excess water also displaces oxygen in the soil which is detrimental to both certain types of microbes and also to plant health.
Roots need to be able to absorb oxygen for respiration to break down the root sugars for energy.
Oxygen is the fuel to making both fires burn hotter and also for plants and animals to burn oxygen and sugars to produce energy.
