less than 100%, which is due to anaerobic bacteria being much less efficient at breaking down organic material. Similarly as in water, oxygen concentration also plays a key role in the breakdown of organic matter in soils. Higher oxygen saturation allows for aerobic bacteria to persist, which break down decaying organic material in soils much more efficiently than anaerobic bacteria. Thus soils with high oxygen saturation will have less organic matter per volume than those with low oxygen saturation.
