What happens when a plant gets excess water.
*Roots lack oxygen-During times of excess water, the plants roots will be lacking oxygen in the root zone.
*Nutrients Become Unavailable; The soil microbial population must access oxygen to survive. As a result, the microorganisms will target 3 nutrients to meet their oxygen requirements; Nitrogren, Manganese, and Sulphur. The first "oxygen source" is nitrate (N03-) nitrogen, followed by Manganese (Mn04) and finally sulphate (s04-) Sulphur. The end result is that these 3 nutrients will be lost or become unavailable resulting in a nutrients imbalance by the plant. This biochemical process is called "oxidation reduction
* The Plant Stops Generating Photosynthesis; With nutrient uptake being significantly limited and the plant "shutting down" it will not be generating ATP and its various sugars and metabolites for optimum plant growth. The end result is the plant will start to turn yellow and look weak.
And by all these it dies

The answer : Following harmful effects cause due to excess water-
The field will get water logged and the crop cannot get sufficient water and air, as good aeration and warmth in the root zone are essential for proper plant growth.
Bacteria that change organic matter into plant foods cannot get necessary air and warm temperature in the soil.
Desirable chemical reactions cannot take place and nutrient availability is not easily to the plants.
Proper root development and absorption of nutrients is not accelerated.
Seed germination is affected due to poor aeration and warm temperature.
Plants affected by diseases and pest attack.
