What does surge irrigation involve?

Surge irrigation involves the intermittent application of water, which means that water is not applied continuously but rather in bursts or surges. This method is designed to optimize water usage by allowing periods of wetting followed by intervals of drying. The drying phase enables the soil to absorb more water during the next surge, effectively improving infiltration rates and reducing runoff.

This approach can significantly increase the efficiency of water use, particularly in furrow or basin irrigation systems, and helps manage soil erosion. By alternating between applying water and allowing the soil to take it up, surge irrigation can also enhance crop health and maximize the benefits of irrigation, making it a popular choice in specific agricultural settings.

In contrast, continuous flow of water does not allow for the absorption and may lead to water wastage. Drip watering is a distinct method focused on delivering water directly to plant roots and does not involve surges. Flooding the entire field is a different irrigation practice, often resulting in waterlogging and inefficient water use. Thus, intermittent application captures the essence of surge irrigation effectively.
