Over-irrigation can lead to waterlogging and root rot, which is a significant concern for crop health. When soil becomes overly saturated with water, it can fill the air spaces that normally allow for oxygen exchange in the soil. This lack of oxygen can stress or kill the roots, preventing them from absorbing necessary nutrients and water.
When roots are compromised due to waterlogged conditions, plants may exhibit symptoms of root rot, which can include yellowing leaves, wilting, and stunted growth. Ultimately, this can lead to reduced yields and even complete crop failure if not managed effectively. It's essential for irrigators to understand the balance required for optimal plant health and to monitor soil moisture levels to prevent such detrimental outcomes from over-irrigation.
