Agriculture is being affected by the price of red diesel, which is subject to a much lower fuel duty rate than normal diesel but can only be used by specific industries.
Jeremy Padfield, a beef and arable farmer based in Stratton-on-the-Fosse, said the price of red diesel had almost doubled.
He told BBC Radio Somerset: “We bought some at 66.5p before the conflict started and we were priced at 115p this week for red diesel.
“The initial fear was the availability, sharply rising cost and a volatile market but it is fluctuating,” he said.
