Water is an essential component for plant growth. In turfgrasses it comprises 75 to 90 percent of the fresh weight of the plant, and irrigation is a key cultural practice in turfgrass management. Only 1 percent of the water absorbed is utilized for metabolic activity. By considering the factors that contribute to water loss, turfgrass managers can devise effective irrigation plans for specific sites.
This publication discusses how to ensure efficient supplemental water management to maintain turfgrass growth by evaluating irrigation system performance. Completing an audit of an irrigation system provides the information needed to set irrigation controllers to deliver the proper amount of water.
