When sodding a slope, how should the strips be laid?

• A. Perpendicular to the contour
• B. Diagonally across the slope
• C. Along the contour
• D. At a 45-degree angle to the slope

Answer: (C)

When sodding a slope, laying the strips along the contour is the most effective method for establishing the grass and preventing erosion. This technique maximizes the sod's effectiveness by aligning the sod with the natural shape of the land. By placing the strips along the contour, water is encouraged to flow along the installation rather than directly down the slope. This helps to reduce runoff speed, minimizes soil erosion, and enhances water absorption, allowing the sod to establish a stronger root system. In contrast, laying strips perpendicular to the contour could lead to increased water runoff and higher erosion risk, as water flows directly down the slope, potentially undermining the sod. Diagonal placements across the slope and at a 45-degree angle may also promote similar runoff issues, failing to effectively slow down water movement and protect the slope's integrity. Therefore, sodding along the contour is aligned with best practices for erosion and sedimentation control, making it the correct choice.
