Waterlogged
Waterlogging refers to the saturation of soil with water. If the soil remains waterlogged and becomes stagnant this can be very detrimental to plant growth as anaerobic conditions occur due to a lack of oxygen. Oxygen is vital for healthy root growth as the cells that make up the roots need to respire, requiring a constant source of oxygen usually found in the poor spaces in un waterlogged soils. Some plants are adapted to survive and flourish in waterlogged conditions, rice (Oryza sativa) for example.
