Sprinkler and flood irrigation differ primarily in their application methods, land requirements, and operational control.

Flood Irrigation

Flood irrigation is a form of surface irrigation where water is applied at the edge of a field and allowed to flow across the entire surface to the opposite side. This method typically requires the land to be graded to ensure uniform slopes, facilitating the movement of water. It is commonly used for grain and forage crops.1

Sprinkler Irrigation

In contrast, sprinkler irrigation involves applying water under pressure, simulating rain. Key differences include:2
* Land Preparation: Unlike flood irrigation, sprinkler systems generally require little or no land grading.1
* Control: Sprinkler systems allow for precise control over application rates and can be used for frost protection or the application of chemicals like pesticides and fertilizers.1
* Efficiency: Sprinkler systems are highly efficient and require minimal labor, though they often rely on pumps to move water from a supply source to the sprinkler units.3
