How does excessive irrigation affect soil health?

Excessive irrigation has a significant impact on soil health, primarily leading to soil salinization and erosion. When too much water is applied to the soil, it can cause the water table to rise, bringing dissolved salts to the surface. This accumulation of salts makes it difficult for plants to absorb water effectively, ultimately harming plant growth and reducing crop yields.

Additionally, the overapplication of water can lead to soil erosion, as excess water can saturate the soil and cause it to become unstable. This instability can result in runoff that washes away topsoil, which is essential for providing nutrients and supporting plant growth.

While water is crucial for plant health, there is a threshold beyond which it becomes detrimental, making careful management of irrigation practices essential to maintaining soil integrity and fertility.
