With the added benefit of Advanced Soil Technology, this high-quality, fast-acting lime maximizes nutrient availability to benefit your lawn whatever the season.
Why does soil pH change?
Soil pH changes for many reasons, including the lime or other products you add. In areas with heavy rainfall, calcium naturally leaches away as rainwater passes through soil. The loss of calcium means soil pH drops and soils become acidic over time. In these regions, lime is usually a necessity for healthy lawns. In areas with very little rainfall, calcium doesn't leach away, and lawns can become too alkaline. Proper lawn maintenance also naturally lowers soil pH over time. Regular fertilization, proper irrigation and increased activity of beneficial soil microorganisms all contribute to gradual, normal drops in soil pH. 2
