Music fans attending this year's Glastonbury festival will be told to use biodegradable tent pegs in an effort to protect the farm's cattle.
Owner Michael Eavis is hoping that the new eco-friendly pegs will help protect his cows.
The pegs are made from biodegradable potato starch, which is strong and already used in the turf industry.
Eavis said the measure was an attempt to prevent grazing dairy cows at his farm becoming injured by metal tent pegs left behind after the weekend summer festival.
Up to 175,000 people attend the annual bash in fields at Worthy Farm, Somerset, the majority of whom bring their own tents.
The metal pegs are "a real problem for the cows", Eavis told BBC News.
He said: "We're going to buy a biodegradable tent peg this year, but it is very stout actually. They use it in the turf industry and we've just discovered it.
"So we're going to force people to use the tent pegs and not use the wire ones."
The move is part of a series of environmental measures called "Leave No Trace" which are to be announced in March.
Registration for tickets to the festival opened on Friday and will stay open until 14 March. Acts already confirmed for the event, which takes place from 27-29 June, include Jay Z, Neil Diamond and British Sea Power.
