4.16 DROP TUBE EXTENSION WITH NH

The delivery drop tube should extend 0.5 in (13 mm) past the stainless steel clips. This usually
prevents mud from freezing to the fertilizer knife.
IMPORTANT: SEED HAWK
ASSUMES NO RESPONSIBILITY IF SEEDLING DAMAGE IS CAUSED
BY ANHYDROUS AMMONIA BURN. THE OPERATOR IS RESPONSIBLE FOR CHECKING AND
SETTING THE SEEDER IN ALL FIELD CONDITIONS.
4.17 PLACING FERTILIZER WITH SEED
IMPORTANT: For the fastest and most ever germination, Seed Hawk
recommends that
growers should not place any fertilizer with the seed.
1. Fertilizer placed directly with the seed will compete for moisture causing slower germination
and reduced plant counts (especially with pulses and oilseeds). The only exception to this is
liquid forms of phosphate.
2. The Seed Hawk
opener allows roots to grow into the fertilizer band very quickly (within
days of germination) so starter fertilizer in not necessary.
3. When fertilizer is placed with the seed, blockage monitors will not sense a problem with the
seed flow.
4. Our agronomists at Seed Hawk
have carefully reviewed the Canola Growers Manual and
other research. The have also seen evidence in fields, field scale trials and their own trials,
which indicates that placing fertilizer directly with the seed a very risky practice.
5. Many field agronomists recommend a starter fertilizer be placed directly with the seed. We
recommend that your field agronomist call our Seed Hawk Agronomists before giving
recommendations to plate ANY fertilizer with the seed on a Seed Hawk
.
The Seed Hawk
Twin Wing™ system is designed to place seed away from the complete blend
of fertilizer. However, if anhydrous ammonia or liquid nitrogen is applied, there may be a
temptation to blend dry or granular fertilizer with the seed. High levels of phosphate fertilizer
placed in close proximity to the seed will cause seedling damage. Oilseeds and pulse crops are
the most sensitive to phosphate burn.
