A light thatch layer is true to say it provides which benefit?

• A. By providing insulation for the roots
• B. By increasing pest resistance
• C. By increasing soil drainage
• D. By reducing water infiltration

Answer: (A)

A light thatch layer acts as an insulating blanket for the roots, buffering the root zone from extreme soil temperatures. By slowing heat gain in summer and heat loss in winter, it helps keep the roots in a more stable, favorable range, which supports turf health and stress tolerance. That’s why insulation for the roots is the best description of the benefit. Pest resistance isn’t a primary benefit of a light thatch; in fact, thatch can become a habitat for pests if it accumulates. Drainage is not typically enhanced by a light thatch, and thick thatch can hinder water infiltration and airflow rather than improve them, so those options don’t describe the main advantage.
