Manufacturers have been showing off the latest hi-tech machinery designed to help farmers get the most from their land at a huge agricultural show in Cambridgeshire.

Here, the BBC's Claire Marshall gives a guided tour of one of these mega-machines - a crop sprayer that can cover 36m of field in one pass.
