Turf grass is ideally grown in a slightly acid soil. The optimum pH range for lawns is 6.5 to 7.0. When a soil becomes too acid or alkaline, some nutrients used by the grass plant become unavailable. To ensure maximum nutrient availability, soil pH must be in the optimum range. When the soil pH is below 6.5, lime should be applied to the soil to adjust acidity. Soil pH above 7.0 is considered alkaline and then sulfur must be applied to lower the pH.
