ABSTRACT
Waterlogging has a major impact on both natural vegetation and agricultural crops. Soil waterlogging occurs when over-irrigation and excessive rainfall combine with poor drainage resulting from soil compaction or poor soil quality, as in the case of heavy fine-textured or layered soils. Waterlogging alters soil properties, such as increasing acidity and reducing oxygen diffusion rate or availability, which can inhibit plant growth and productivity. The most detrimental effect of waterlogging is oxygen deficiency in the soil, because roots are particularly sensitive to anaerobic conditions, which can severely affect nutrient relations of the soil (1). In waterlogged soils, air spaces filled with water delay diffusion of gases between atmosphere and the rhizosphere, leading to oxygen deficiency (2).
