How does higher mowing influence irrigation needs?

• A. It increases irrigation needs
• B. It has no effect on irrigation needs
• C. It decreases irrigation needs
• D. It only affects water usage efficiency

Answer: (C)

Higher mowing can decrease irrigation needs primarily due to the increased leaf area and root development that result from cutting grass at a higher level. When grass is left longer, it can develop a more extensive root system, which allows the plant to access moisture from deeper soil layers. This deeper rooting can lead to better drought resistance and a reduction in the frequency and volume of irrigation required. Additionally, taller grass retains more moisture due to reduced evaporation rates. The longer blades provide shade to the soil surface, which helps conserve soil moisture. Therefore, by maintaining a higher mowing height, the grass can require less water, ultimately leading to decreased irrigation needs. This understanding is critical for effective turf management and can lead to more sustainable practices, conserving both water and resources over time.
