Foot Pedal Irrigation Practice Test

The minimum pressure recommended for standard foot pedal irrigation efficiency is 20 psi. This level of pressure ensures that the irrigation system can effectively deliver water to the intended areas without creating issues such as inadequate coverage or uneven distribution. At 20 psi, the system maintains a balance that allows for optimal functioning of the foot pedal mechanism, ensuring that water flow is sufficient to irrigate the targeted zones thoroughly.

While lower pressures like 10 psi, 15 psi, or even 25 psi might seem viable, they either fall short of delivering adequate efficiency or could lead to unnecessary strain on the system. Insufficient pressure may lead to weak water flow, affecting the irrigation coverage and increasing the chances of dry spots in the field. Conversely, 25 psi might be more than necessary, potentially causing excessive runoff or waste of water, which is not ideal for efficient irrigation practices. Thus, establishing 20 psi as the minimum strikes the right balance for effective irrigation performance.
