Adjustments
(a)

For wheat, an additional 20kgN/ha is permitted for every tonne that the expected yield exceeds the standard yield.

(b)

For wheat, an additional 40kgN/ha is permitted to milling wheat varieties.

(c)

For barley and oats, an additional 15kgN/ha is permitted for every tonne that the expected yield exceeds the standard yield.

(d)

On winter oil seed rape, the spring application can be increased by up to 30kgN/ha if the expected yield is over 4.0t/ha.

(e)

On spring barley, an additional 15kgN/ha is permitted for high N grain distilling varieties.

There is no upward adjustment for excess winter rainfall on N Residue Group 1 Crops
