Which material is the most commonly used to raise soil pH when establishing turfgrasses?

Limestone is the most commonly used material to raise soil pH, especially when establishing turfgrasses. This is because limestone, primarily composed of calcium carbonate, reacts with the acids in the soil to neutralize them, effectively increasing the pH level. A higher pH level creates a more alkaline environment, which is often necessary for optimal turfgrass growth, as many grass species prefer a pH range between 6.0 and 7.5.

In the context of turf establishment, having the correct pH is crucial because it influences nutrient availability and overall soil health. If the soil is too acidic, essential nutrients might become less available to plants, leading to poor growth and increased susceptibility to diseases. By applying limestone before planting turfgrasses, you create a healthier growing medium, promoting robust root development and lush foliage.

Other materials mentioned, such as gypsum, compost, and potash, serve different functions in soil management. Gypsum is primarily used to improve soil structure and provides calcium and sulfur without affecting pH. Compost can enhance soil fertility and organic matter content but does not significantly affect soil pH. Potash is mainly a source of potassium and is more beneficial for providing specific nutrients rather than adjusting pH levels. Therefore, limestone
