The new rules state that uninhibited solid urea can only be used from 15 January to 31 March, as part of efforts to limit emissions. The new rules only apply to England and affect any fertiliser that contains 1% or more of urea and is soil-applied.  It means solid urea fertilisers must be used with an inhibitor for most of the year.  Uninhibited liquid urea can be used from 15 January to 31 March but must be used with an inhibitor from 1 April unless agronomic justification is provided by a FACTS-qualified farm personnel or adviser.  Compliance will be overseen by Red Tractor, with farm inspections including records of responsible fertiliser use.
