Timing of application
Apply nitrogen as a top-dressing just before emergence.
Narcissus, subsequent years
A top-dressing of 50 kg N/ha may be required in the second or subsequent year if growth was poor in the previous year.
Don’t forget to:
- make allowance for nutrients applied in organic manures (see Section 2)
- ensure the phosphate and potash offtake is balanced by application on Index 2 soils and check that the soil is maintained at Index 2 by soil sampling every 3 – 5 years
