Chicken farms may explain decline of the River Wye, tests suggest

Citizen scientists find high phosphorous levels in the soil could be polluting the river in Herefordshire

Campaigners have revealed the results of farmland testing which provides new evidence of the potential link between intensive poultry units and the decline of the River Wye.

Citizen scientists sampled farmland along public footpaths near a tributary to the river in Herefordshire. They discovered the soil with the highest levels of phosphorus, which can blight a river, were close to intensive poultry units.
