The Advertising Standards Authority has issued guidance to advertisers to make sure consumers aren't misled about the term "regenerative agriculture". Scotland's first minister John Swinney says inheritance tax changes in the budget are causing unacceptable levels of stress among farmers in Scotland. We’re discussing farming in Scotland all this week. The new agriculture act now requires every farmer and crofter to complete an annual whole farm plan in order to claim their basic support payments. The plan is a series of audits to measure things like the carbon footprint and biodiversity, and the aim is to identify where and how farmers can make their businesses more sustainable and environmentally friendly. The first reports are due next May and while a lot of advice is available from the agricultural advisory services, the whole farm plan has caused confusion and uncertainty for some farmers. The Wildlife Trusts have bought a chunk of the Rothbury Estate in Northumberland, now they've begun a £30 million appeal to buy the rest. We ask what it means for food production and the tenant farmers who live and work there. Presenter = Caz Graham Producer = Rebecca Rooney
