How is water logging defined and what are its effects?
Waterlogging happens when the soil gets saturated with water and can’t absorb any more. It usually occurs when there’s too much water, like from heavy rainfall or poor drainage. Here’s what you need to know about its effects:
Crop Damage: Plants don’t grow well in waterlogged soil because their roots can’t get enough oxygen. This can lead to poor crop yields or even crop failure.
Soil Erosion: Excess water can wash away the top layer of soil, leading to erosion and loss of fertile land.
Reduced Soil Fertility: Waterlogged soil can lead to nutrient leaching and a reduction in soil fertility, making it harder to grow healthy plants.
Increased Pests and Diseases: The soggy conditions are perfect for pests and diseases, which can harm plants and reduce yields.
Infrastructure Damage: Waterlogged areas can damage roads, buildings, and other infrastructure, leading to costly repairs.
Water Pollution: Standing water can become a breeding ground for bacteria and other pollutants, potentially affecting local water sources.
In short, waterlogging can cause big problems for agriculture, the environment, and infrastructure, making proper water management crucial.
