Detailed explanation-1: -Waterlogging occurs when there is too much water in a plant’s root zone, which decreases the oxygen available to roots. Waterlogging can be a major constraint to plant growth and production and, under certain conditions, will cause plant death.
Detailed explanation-2: -What is waterlogging and flooding? Soils become waterlogged when water is unable to drain away. This leaves no air spaces in the saturated soil, and plant roots literally drown. Waterlogging is common on naturally poorly drained soils or when heavy soils are compacted.
Detailed explanation-3: -Waterlogging is a condition which occurs when the soil in a particular region is completely saturated with water. Disadvantage: Waterlogging damages the crop. Due to excessive water supply, the air in the soil spaces is reduced and the roots of the plants get damaged.
Detailed explanation-4: -Causes of water logging: These include inadequate drainage, improper balance in the use of groundwater and surface water, seepage and percolation from unlined channels, overwatering, planting crops not suited to specific soils, and inadequate preparation of land before irrigation.
