Paddy Farragher has being running an agricultural contracting business for over 52 years and he has being an agent for McGraths since the 1970’s delivering and spreading McGraths Grolime in many areas of south Mayo and north Galway.

“The farmers we deal with who spread McGraths Grolime find a significant improvement in their pasture. There are several key reasons for this- McGraths Grolime is a quality product which tests have shown improve fertilizer availability to the crop. It also improves the root structure of the plant, the drainage and aeration in a well limed soil is better due to more earthworm activity, but more importantly it is the unique fine texture of McGraths Grolime that contributes highly to positive results for farmers. I have working with McGraths over many decades and together we have delivered a prompt and reliable service and have built up a relationship and reputation with many satisfied customers.”

On Friday, McGraths Limestone Cong hosted our charity event, Mindful Miles, in support of @mayomha. We gathered at the Neale GAA Pitch, to take part in a team relay challenge, with the goal of collectively walking and running the distance of a marathon. Thanks to the incredible effort of everyone involved, we exceeded our target, completing 255 laps, covering the equivalent of 5.5 marathons! 🏃‍♀️🏃‍♂️ We were delighted to welcome Mayo footballers Tommy Conroy, Tom Lydon and Pádraig O'Hora, from Mayo Mental Health Association, along with Lianne McManamon and John Hughes. So far, we have raised almost €10,000! A huge thank you to everyone who has donated, participated, volunteered, and supported the event! Can you help us get to 10K? Following a fantastic afternoon of fundraising and team spirit, we enjoyed a cruise on Lough Corrib with Corrib Cruises. A sincere thank you to Captain Pat Luskin and his crew for taking care of us, and for the great food from Bia at Home.

🌱 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.
