Understanding Soil pH and Its Importance
Soil pH is a measure of the acidity or alkalinity of the soil, with a pH of 7 considered neutral. Most grass types thrive in slightly acidic to neutral soil, with an optimal pH range between 6.0 and 7.0. However, soil pH can vary significantly due to factors like soil composition, organic matter content, and environmental conditions. If the soil pH becomes too acidic or too alkaline, it can negatively affect nutrient availability, microbial activity, and overall plant health.
The Role of Lime in Soil pH Management
Lime, specifically agricultural lime or dolomitic lime, is commonly used to raise the pH of acidic soils. It works by neutralizing hydrogen ions, which are responsible for soil acidity, thus creating a more favorable environment for plant growth. Lime also provides calcium and magnesium, essential nutrients for plants. The application of lime is a critical step in soil management, particularly for lawns, as it can significantly improve soil fertility and structure.
