Which keyword is associated with healthy turf maintenance?

1. Moisture

2. Thatch

3. Fertilizer

4. Drainage

The correct answer is: Drainage

The association of drainage with healthy turf maintenance is crucial because proper drainage ensures that excess water does not accumulate on the surface or within the soil. This prevents various problems, including waterlogging, which can suffocate grass roots and lead to disease. Effective drainage allows for better oxygen flow to the roots and minimizes the potential for fungal diseases, thereby promoting a healthier, more resilient turf. While moisture is important for sustaining grass and enabling growth, it must be balanced with adequate drainage to avoid negative effects such as root rot. Thatch refers to a layer of organic material that can build up on the soil surface, which can impede water absorption and nutrient availability if it becomes too thick. Fertilizer contributes to nutrient availability for grass, but without proper drainage, the added nutrients may not be beneficial due to the waterlogged conditions that can occur. Therefore, drainage is a fundamental aspect of healthy turf maintenance as it supports overall soil health and grass vigor.
