Ulster farm minister Michelle O'Neill stressed that the onus now fell on farmers to quickly check their maps and flag up any such mistakes for correction.
"I am aware a problem has occurred with the production of some of the maps, with a number of them missing fields that were declared by the farmer in the 2012 scheme period," admitted Mrs O'Neill. "This particular problem is restricted to a sub-set of maps within the last batch produced.
"It is vitally important that farmers check their maps and report necessary changes. This remains the case, including for those farmers who find there are fields missing from their maps. If a farmer has a problem with his/her maps, they should contact their local DARD Direct office and arrange an appointment," she stressed.
"We will provide replacement maps for affected farmers and will work directly with them/agents to make sure that they have the necessary information in time to complete their Single Application Forms.
"I regret this problem has occurred and am grateful to all the farmers and their agents who have been working closely with us," she added. "I hope to continue to work in this way to develop a stable mapping system which is accurate and can support farmers making accurate claims for area-based schemes. "
