Question

Influence of soil ph in microbial flora

Answer 1

Answer:

There is a direct impact of pH on the microbe but it is important to consider also the impact on (1) rhizodeposition and crop residue utilisation as the principal substrates for microbial growth and (2) the physico-chemical environment of soil as a water-stable structure

Answer 2

Answer:

Most microorganisms have an optimum pH range for survival and function (see table 2). At very acid or alkaline pH levels, organic matter mineralization is slowed down or stopped because of poor microbial activity linked to bacteria. ... Some diseases thrive when the soil is alkaline or acidic.
