The activities of microorganisms in the soil are affected by a large number of factors and one of the principal ones is the hydrogen ion concentration of the soil. The decomposition of organic matter may take place at a low pH as well as at a high pH; however, the type of organisms responsible for decomposition varies at different pH values and the rate and character of the decomposition may also change considerably.
