Teagasc yield assessments found all fertilisers – CAN, urea and protected urea – "performed the same". Photo: Roger JonesResults from Teagasc’s latest trials on protected urea application to grasslands have found no evidence of milk residue issues, it has been confirmed. On new research that tested milk samples for potential to contain residues of protected urea Dr Forristal explained that “a highly sensitive” method to detect the urease inhibitor was developed, alongside a method to preserve samples. Fertiliser effectOn yield assessment — including cutting trials, grazing trials and long-term cutting trials at Johnstown Castle where fertiliser has been repeatedly applied to the same plot – Dr Forristal stated that all fertiliser (CAN, urea and protected urea) “performed the same”. “It’s a slightly cheaper product to grow the same amount of grass versus CAN and protected urea has lower greenhouse gas emissions.
