Waterlogging produces a process of suffocation to plant, making the process of respiration inadequate. This suffocation process occurs when the soils accumulates a large amount of water that occupies the air spaces from soil. Since the process of respiration is inadequate, harmful gases such that carbon dioxide and ethylene accumulate and the root tissues start to decompose. The decomposition process hampers the growth of the plant and the plant is invaded by decay organisms.
Since the needs regarding the amount of oxygen depend on the stage of growth of plant, the consequences of waterlogging may vary. It is also important to stress that summer waterlogging can be more damaging than winter waterlogging, since the need of oxygen is increased in warm seasons.
