For some, it's been the earliest harvest ever in the UK. We join Adam Henson on his farm to find out if he's being persuaded by pioneering neighbour David Wilson to give regenerative farming a go. It's the big new buzzword in agriculture, but how do Adam's conventional crops compare to David's heritage breeds? And who comes out on top in terms of profit and for soil health?As energy costs rocket, Charlotte Smith finds out whether methane might be fuelling our tractors in the future and also if a giant grass could help to heat our homes. Tom Heap investigates why British farmers need to grow more protein, and we meet the Norfolk whisky maker who reckons he can give the Scots and the Irish a run for their money.
