Which type of irrigation can also control the timing of water application?

Surge irrigation is an advanced method of surface irrigation that allows for the timed application of water to the field. In this technique, water is applied in a series of pulses or surges rather than as a continuous flow. This approach enables farmers to control the amount and timing of water application more effectively, facilitating better water management and improving irrigation efficiency.

By using surge irrigation, the water is allowed to infiltrate the soil during each surge, creating a controlled environment that helps in proper moisture distribution and reduces excess runoff. This timing control can be particularly beneficial in managing soil moisture levels and reducing evaporation losses, making it a preferred choice for certain agricultural scenarios.

In contrast, the other methods like flood irrigation and subsurface irrigation do not inherently offer as much control over the timing of water application. Flood irrigation typically involves a continuous flow of water over the surface, while subsurface irrigation delivers water directly to the root zone, which might not allow for adjustments in timing as effectively as surge irrigation. Sprinkler irrigation, while it can control application rates, does not inherently provide the same surge action that aids timing control found in surge irrigation.
