A bid to scrap new rules to limit the use of slurry and fertiliser on farmland in Wales failed in the Senedd on Wednesday.
Opposition parties tried to scrap the strict new rules the Welsh government hopes to bring in from April.
Farmers have expressed fury with the plans, and unions said it could cost the industry £360m.
But the fishing community and environment groups said it was vital the restrictions go ahead.
