Overview
The Dairy Celts discussion group project, covering Pembrokeshire and Carmarthenshire is titled “Does lowering phosphate in feed mean a lower phosphate in manures without affecting efficiency?” The project’s objective is to test a hypothesis that phosphate levels in dairy cattle feed are significantly above biological need, and that a reduction in feed phosphate will reduce phosphate levels in manure and thus decrease phosphate surpluses lost to soil and water. The data & learnings generated could thus apply to a much wider dairy farming base than just Dairy Celts.
