Scots welcome derogation for autumn N

The derogation allowing Scottish growers to apply autumn nitrogen in Nitrogen Vulnerable Zones is likely to be repeated this year, according to SAC’s Alex Sinclair.

The move will be welcomed by some Scottish growers who believe autumn nitrogen is useful to help maximise yields.

This is despite trial results that have shown that autumn nitrogen offers no advantage when it comes to final yield.

“The application of autumn nitrogen is cosmetic and unnecessary,” he said.

“But growers in Scotland want it,” said Mr Sinclair.

“Growers in England haven’t been applying nitrogen in the autumn since the 1980s and yields have not suffered.”

Trails are continuing to research the use of autumn nitrogen, added Mr Sinclair.
