A man has died after falling from a wall on his farm in Co Londonderry.
Father-of-three Henry Allen, 70, is believed to have lost his balance while working with silage, according to friends.
His only son David worked with him on the farm near Moneymore.
The Mid Ulster Unionist MLA Sandra Overend said: "This is a busy time of year for farmers, and the change in weather brings its own demands and challenges in order to look after their animals."
She added: "This tragedy serves as another sad reminder of the risks that farmers face in their profession on a daily basis."
Last year 12 people died in farm accidents in Northern Ireland, including Ulster rugby star Nevin Spence, his father and brother, who were overcome by fumes in a slurry tank on their farm outside Hillsborough, Co Down.
Twelve died in 2011. There were two fatalities up until June this year, according to the Northern Ireland Health and Safety Executive.
