# The Action Programme for Nitrate Vulnerable Zones (Scotland) Amendment Regulations 2009, Regulation 9: Amendment of Schedule 3


(1) Schedule 3 (calculation of maximum nitrogen application to crops) is amended as follows.
(2) For Table 1, substitute—
“
Table 1
Nitrogen Residue Group 1 – Previous Crops in Nitrogen Residue Group 1 are: cereals, carrots, swedes, turnips (removed) & linseed

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
