What condition can lead to a decreased population of turfgrass?

• A. Healthy watering practices
• B. Thatch build-up
• C. Dense planting
• D. Good pest management

Answer: (B)

Thatch build-up is a condition characterized by an accumulation of organic matter, such as dead grass blades and roots, that creates a dense layer on the surface of the soil. This layer can inhibit water infiltration, air movement, and nutrient absorption, ultimately harming the grassroots of the turf. When turfgrass is unable to access these essential resources, it can suffer from stress and decline, leading to a decreased population. Additionally, excessive thatch can create a favorable environment for pests and diseases, further compounding issues with turf health. In contrast, healthy watering practices, dense planting, and good pest management typically support turfgrass growth and resilience. Proper watering ensures that the grass receives adequate moisture, while dense planting, when managed correctly, can lead to a lush and thick lawn. Effective pest management minimizes threats from insects and diseases, promoting a robust turf population.
