Earthway Fert-A-Ply Side-Dress Fertilizer Attachment 1500
Product Review (submitted on September 22, 2012):
Easy to attach to Earthway planter and works well. Down side is the open/close mechanism. ( agree with love it hate it opinion) Had to tie drag chain up to make sure it was dispensing fertilizer. This is fine if you are side dressing but a pain if you are fertilizing before planting.
