Soil pH affects turfgrass health by influencing availability of plant nutrients and other elements, thatch decomposition, some turfgrass pests, and pesticide activity.

Strongly acidic soils may lead to deficiencies in calcium, magnesium, or phosphorus and increase availability of aluminum and manganese in amounts that may be toxic to turfgrasses. Liming improves plant nutrient availability and reduces toxicity problems in acid soils.
