Which of the following factors is essential for maintaining good turf health?

Proper drainage is essential for maintaining good turf health because it directly affects the root system and overall vigor of the grass. Healthy turf requires well-aerated soil that allows for the movement of air, water, and nutrients. If drainage is inadequate, water can accumulate, leading to waterlogged conditions that suffocate roots, promote disease, and create an environment conducive to pests.

In contrast, regular foot traffic can compact the soil, adversely affecting drainage and root development. Frequent heavy watering may lead to over-saturation, which can also promote fungal diseases and shallow rooting. Neglecting mowing schedules can result in uneven turf growth, potentially leading to pest issues or nutrient deficiencies. Therefore, focusing on proper drainage supports a robust turf environment that can thrive under various conditions.
