A major chicken producer claims it will clean up its use of manure alongside the River Wye but its plan won't be fully implemented till 2025. Avara Foods has 120 farms producing 16 million chickens for it within the River Wye catchment. It's faced criticism for failing to ensure the farms do not contaminate the river by spreading chicken manure on their land. Now the company says it will bring in a new regime which will regulate the use of the farms' manure much better and will not "contribute to excess phosphate in the Wye" by 2025. Nicola Cutcher from the Guardian has had exclusive access to Avara - she told us what the new company plan is. All week we're talking about peat.
