Work Step by Step
Irrigation can result in the accumulation of salts in soil (salinization) and waterlogging of soil and plant roots, leading to environmental problems. The increased water supply from irrigation can cause salts to accumulate in the soil as water evaporates, making it less suitable for plant growth. Additionally, over-irrigation or poor drainage can saturate the soil, reducing oxygen availability to plant roots and potentially harming crops.
The answer is (e).
