The agricultural minister will provide spiritual support to farmers and their families, as well as counselling.
They will also champion Scotland's rural industry and farmer's rights, and encourage people to buy locally produced food.
The post's due to be advertised in the next few weeks, and will run as a five-year pilot scheme when more farming minister positions will be created if necessary.
Revd Dr Angus Morrison, Moderator of the General Assembly of the Church of Scotland, said: "It is hoped that through this new position the Church can meet farmers where they are and build relationships that will allow an understanding of the issues and stresses related to modern-day farming.
"The Church cares deeply about people in all our communities and I am confident that whoever fills this important role will make a substantial difference to the lives of many people."
