How farmers could fix Wales' polluted rivers and save money

A study in Pembrokeshire, Wales, found that dairy farms are overusing fertiliser and animal feed, leading to high phosphorus levels in the soil and polluting local rivers. By calculating their nutrient footprint, farmers could reduce waste, cut fertiliser costs by up to £1 million annually, and improve water quality. The research highlights agriculture as the main cause of pollution in the Cleddau rivers, which are among Wales' most degraded protected waterways. The findings suggest that better nutrient management could both protect the environment and save farmers money.
