Detailed explanation-1: -Waterlogging: Waterlogging occurs when there is too much water in a plant’s root zone, which decreases the oxygen available to roots and Capillary fringe reaches the root zone of the plant. 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? Waterlogging is excess water in the root zone accompanied by anaerobic conditions. The excess water inhibits gaseous exchange with the atmosphere, and biological activity uses up available oxygen in the soil air and water – also called anaerobiosis, anoxia or oxygen deficiency.
Detailed explanation-3: -Waterlogging is caused by a combination of excess rainfall (for the site), poor external drain-age (runoff), poor internal drainage (water movement in the soil profile) and the inability of the soil to store much water.
