Evaluate the following statement: In high-sand rootzones used on golf greens and high-performance sports fields, higher organic matter content is better.

• A. True
• B. False
• C. Not enough information
• D. Only for fairways

Answer: (B)

In sand-based rootzones for golf greens and high-performance fields, drainage and surface firmness are the top priorities. Sand creates large, connected pores that drain quickly and keep the surface stable under traffic. Adding more organic matter tends to fill those pore spaces, increasing water retention and reducing drainage. That can lead to a softer, more inconsistent surface, more thatch buildup, and uneven playability. While some organic matter helps with nutrient buffering and biology, these systems are designed to be low in organic matter to preserve drainage and stability. So, higher organic matter content is not better.
