What aspect of soil drainage contributes to healthy turfgrass?

1. It prevents waterlogging

2. It allows for better root development

3. It promotes healthy turfgrass

4. It reduces the need for irrigation

The correct answer is: It promotes healthy turfgrass

The aspect of soil drainage that directly contributes to healthy turfgrass is primarily linked to its role in promoting overall turfgrass health. Good soil drainage ensures that excess water is effectively removed from the root zone, preventing conditions that could lead to disease and root rot. When water can drain adequately, it encourages a robust and resilient turfgrass ecosystem because the roots can access oxygen and nutrients more efficiently. Additionally, healthy soil drainage minimizes stress on the turfgrass by avoiding prolonged periods of saturation that can stunt growth and weaken plant vigor. As a result of proper drainage, turfgrass can establish a strong root system, which in turn supports a healthy and dense lawn while maximizing the turf's ability to withstand environmental stresses. Maintaining optimal drainage conditions allows for balanced soil moisture levels, which ultimately leads to a more lush and thriving turfgrass.
