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.”
