Absolute trust between customers and ourselves is a core value of this company since its foundation. It is the duty of everyone working for this company to foster this core value, and never betray this trust.

J Grennan & Sons is a family owned Agri-trading business. We have been involved in farming for many generations and in Agri Trading since 1878. Our trading business has developed from very small, solely retail beginnings, into one of the leading importers, manufacturers, wholesalers and retailers of farm inputs in Ireland.


Our core business is the manufacturing and distribution, at both wholesale and retail level of Animal Feeds, Farm Fertilisers and Agricultural Seeds. The retailing and wholesaling of Agrochemicals, Farm Hardware and Farm Plastics are also integral parts of our business.
