🌱 Soil Success Starts with Lime Applying lime helps correct soil acidity, improving soil pH and making nutrients more readily available to plants. This supports stronger grass growth, better fertiliser efficiency, and improved farm productivity. By maintaining the correct soil pH, farmers can grow more grass, reduce feed costs, and maximise the return on their investment.

We're proud to have recently partnered with @coisteforbarthachorrnamona by donating materials to repair the slipway at Cornamona Pier. Thanks to the hard work and dedication of local volunteers, the slipway is now safer and more accessible for everyone who uses it. The project was completed just in time for the annual Currach Race, helping ensure boats could be launched and recovered with ease. At McGrath's, we're always delighted to support projects that make a positive difference in our local communities. 👏 Well done to everyone involved. #McGrathsCong #CommunitySupport #LocalCommunity #CurrachRacing #ProudToSupportLocal #Galway #CommunitySpirit
