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)

High-sand rootzones aim for fast drainage and strong root aeration. Organic matter tends to hold more water and can clog the pore structure of sand, reducing drainage and increasing the risk of a perched water table after irrigation or rain. It can also lead to thatch formation and a softer, less stable playing surface, which hurts firmness and ball roll on greens and high-performance fields. Because the goal with these surfaces is to maintain quick, uniform drainage and solid playability, higher organic matter content is not better. In practice, these rootzones use predominantly sand with only small, carefully controlled organic amendments to avoid compromising drainage and surface quality.
