🌧️ With Ireland’s heavy rainfall, soils naturally become more acidic – creating a need for lime.

✅ Applying Grolime helps neutralise soil pH:

6.3 for mineral soils

5.5 for peaty soils

The right pH balance improves nutrient availability, grass growth, and overall soil health. 🌱

Don’t guess — test! ✅🌱
