Overview: This fertilizer applicator knife delivers NH3 through a nylon insert, insulating the fertilizer knife from the NH3. This prevents moist soil from freezing up and building up on the knife, keeping it narrow to reduce disturbance with minimal gassing off. Not recommended for rocky conditions.

Notes: Installation bolts sold separately. Use 1/2” Grade 8 Hex Head bolts.
