Flooding sock, TB genetic index, Potato vending machine

As the post-flood clear-up continues, we're exploring ways in which farmers may be able to help prevent future flooding, by keeping water upstream. In this programme we hear about a gigantic sock which can help hold water back, and keep it upstream in farmers' fields.

A new index of genetic information will be launched next week, which farmers can use to help breed resistence to bovine TB into their herd. Anna Hill asks the head of genetics at the dairy branch of the Agriculture and Horticulture Development Board how it will work.

All this week we're looking at ways in which farmers and food producers are by-passing the big retailers to connect directly with their customers. Today Nancy Nicolson finds out about a vending machine dispensing potatoes in Dundee.

And it's wassailing time! If you want a good apple crop for cider, you need to be in good voice.

Presented by Anna Hill and produced by Emma Campbell.
