Vitax Q4N
10-7.5-10.2 + 1.7Mg + TE (0.012% Boron, 0.015% Copper,
0.2% Iron, 0.012% Manganese)
A high
nitrogen, extended release formulation
An ideal
formulation for all containerised nursery stock and field grown tree and shrub
stock. It can be used as a base and top dressing.
When used
in tree and shrub planting, Q4HN can be added to the backfill to meet the full
nutrient requirements of the plant and promote healthy root development and
successful establishment.
When used
with nursery stock, Q4HN provides top quality overall growth rather than just
spectacular leader growth, which is the case with some fertilisers.
Because the
nitrogen is from a variety of sources, nutrients are released in phases. Extra
iron in the formulation is particularly beneficial to ericaceous plants, and
the organic content increases humus and bacterial levels in growing media.
