IRRIGATION: IRRIGATION SYSTEM MAINTENANCE

Irrigation management involves maintenance of the system as well as scheduling irrigation. Maintenance involves cleaning, repairing, and replacing components as necessary to maintain an efficient and properly operating system.

Periodic visual inspection of sprinkler heads and their operation is usually sufficient. Once a year the nozzles may be checked with an appropriately sized drill bit for change in size due the wear or clogging. In addition to routine maintenance, the system should be checked for clogging and uniformity of water application.

Irrigation scheduling involves a decision-making process of when to irrigate and how much to apply or how long the system should be operated. The scheduler must decide on the objective of the irrigation and the type of information required for accomplishing scheduling. Objectives may involve drought stress avoidance, frost protection, or crop cooling.
