Syringing helps restore soil moisture lost to evapotranspiration.

• A. True
• B. False
• C. Only for sandy soils
• D. Not necessary

Answer: (B)

Replenishing soil moisture requires water that actually reaches the root zone to offset what is lost through evapotranspiration. Evapotranspiration includes both evaporation from the soil surface and plant transpiration, so simply wetting the leaf surface doesn’t reliably return water to the root zone. Syringing applies a fine spray to the turf surface to cool the leaves, and much of that water either evaporates from the leaf surface or runs off rather than soaking deeply into the soil. Because root-zone moisture is what supports plant water needs during ET, syringing is not an effective method to restore soil moisture lost to evapotranspiration. It’s mainly used for cooling and providing temporary surface moisture, not for refilling the root-zone reservoir. For restoring soil moisture, deeper, properly timed irrigation that allows water to infiltrate into the root zone is required.
