The results of a Teagasc trial on protected urea have been published, which show “further reassurance that protected urea can be part of a toolbox of solutions for Irish agriculture”, the agricultural authority has revealed.
A new scientific paper was published this week with results from a trial on using protected urea on the Teagasc farm at its Environment research centre in Johnstown castle.
Some concerns were raised by industry about the potential for protected urea residues to appear in milk, Teagasc notes.
The published paper details the development, at Teagasc, Ashtown, of a highly sensitive and validated analytical method for the detection of the urease inhibitor NBPT and NBPTo in the matrix of milk.

A new scientific paper from Teagasc confirms that no chemical residues were found in milk produced from cows grazing grass treated with protected urea fertiliser in milk sampling trials.
The research, which was conducted by Teagasc at its environment research centre in Johnstown Castle, aimed to tackle concerns about the potential for protected urea residues to appear in milk.
Senior research officer in the Teagasc crops, environment and land use programme Dr Patrick Forrestal said: “Extensive trials by Teagasc over the past nine years have shown protected urea to be a solid yield performer in Irish grassland and thus a reliable fertiliser option for farmers.
