|A high nitrogen, extended release, formulation.
A high nitrogen, extended release formulation that is ideal 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.
