4.13 DROP TUBE EXTENSION with NH3
The delivery drop tube should extend 0.5 in (13 mm) past the stainless steel clips.
This will prevent 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.
4.14 PLACING PHOSPHATE FERTILIZER WITH SEED
IMPORTANT: Seed Hawk does not recommend placing phosphate
fertilizer directly with the seed.
The Seed Hawk Drill double-shoot 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.
