*Low-Bush blueberries
can be expected to have a lower N requirement
per plant because plants are
smaller.

by specialist.
- in liner beds - 50 kg N/ha before planting for coniferous
and deciduous stock. No additional N in first year.
- established stock
- in second and subsequent years apply 100 - 150 kg N/ha in 2 to 4 applications
for coniferous and deciduous stock.

to be recommended by Fruit and Vegetable Specialist using plant analysis. Suggested
