The new show will give fans of the long-running radio soap an extra insight into their favourite characters, but will also work as a stand-alone drama.
Vanessa Whitburn, editor of The Archers and Ambridge Extra, said: "Ambridge Extra is an added bonus for listeners who want to spend more time immersed in Ambridge life.
"BBC Radio 4 Extra gives us the space to explore the lives of Archers' characters in more detail. And it is a lovely way to mark the 60th anniversary year."
Two series of the show have been commissioned, running over 13 weeks, with the first airing from Tuesday, April 5. It will air on Tuesdays and Thursdays at 10am and 2.15pm, while the omnibus will broadcast on Fridays and Sundays.
