Why might a superintendent add lime to the fairways?

Adding lime to the fairways primarily serves the purpose of reducing acidity and raising the soil pH. This is crucial for creating an optimal growing environment for turfgrass, as many grass types thrive in slightly acidic to neutral pH levels. When soil pH is too low, it can lead to nutrient availability issues, making it difficult for grasses to absorb essential nutrients, thereby hindering growth and overall health.

Lime, which is made primarily of calcium carbonate, helps neutralize soil acidity. As the acidity decreases and the pH level rises, the soil becomes more conducive to nutrient uptake, which can improve the vigor and resilience of the turf. Furthermore, a proper pH level enhances microbial activity in the soil, which is beneficial for overall soil health and structure.

While improving moisture retention, soil texture, or nutrient retention are important factors in turf management, they are not the primary reasons a superintendent would add lime to the fairways. The main goal is to address soil pH and acidity, ensuring that the turfgrass can thrive in a balanced soil environment.
