Effects of pH and Microbial Composition

A major problem for composting plants is odor emissions. This research links the correlation between low pH with slow decomposition and the impacts on odors and microbial growth.

Aerobic bacteria that effect bio-oxidation exist in the liquid film surrounding the particles in a compost pile.
