🧪 When Was Your Last Sample? 🌱
Soil sampling every 3–5 years is key to keeping your pH levels in check. It’s the only way to make sure your soil stays in the optimum range for both grassland and tillage. Healthy soil = better growth. Don’t guess it — test it! ✅🌾
#SoilSampling #FarmSmart #grolime #timetotest #mcgrathspremiumlime
🔬 Mind Your pH! 🌾
For mineral soils, keep your pH on point — aim for 6.3 on grassland and 6.5 for tillage. A balanced pH means better nutrient uptake and stronger yields. Stay sharp, monitor regularly! 📈🌿
 #SoilHealth #pHMatters #grolime #timetolime #mcgrathspremiumlime
🌱 Boost Your Grass Yield Year-Round! 🌱
Lime can be applied any time, but right after silage is ideal — with bare soils, you get the maximum impact. Don’t miss the chance to improve soil pH and increase annual grass production. Spread smart, grow strong! 💪🚜 #timetolime #grolime #mcgrathspremiumlime

🔨 Preserving the Past in Cong Village 🏛️
We’re proud to be playing our part in safeguarding a piece of local history — the Forge in Cong, a treasured heritage structure that has stood for generations as a symbol of craftsmanship, community, and tradition.
💬 Historically, forges like this were the heart of rural Irish villages — where blacksmiths crafted tools, shoed horses, and played an essential role in the everyday life of the local community. The Cong Forge is one such gem, carrying with it the stories of countless hands and hardworking days.
🧱 At McGraths Limestone, we are currently restoring the forge’s roof with the original slates, which suffered weather damage in recent years. As a company rooted in the region’s natural resources and rich heritage, we are deeply committed to preserving and protecting these important landmarks.
✨ Our mission goes beyond stone — it's about honouring tradition and supporting the cultural fabric that connects past and present.
Stay tuned for progress updates and more glimpses into this beautiful project and please share any information or stories you have on this beautiful building. 🛠️
