Seed Hawk TOOLBAR 2008 - Manual (Page 52)

OPERATION
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.
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.
