High nitrogen liquid fertilizers have been a controversial issue in organic farming in the past few years. In fact, one manufacturer of a high nitrogen liquid fertilizer has pled guilty to fraudulently adulterating product with prohibited materials. Additional requirements now apply to high nitrogen liquid fertilizer use in organic production.
As a result of this NOP directive, CCOF’s liquid fertilizer policy requires any liquid fertilizer product with a nitrogen claim greater than 3% to be approved by OMRI or WSDA. Use of any high nitrogen liquid fertilizer that has not been verified as compliant with the December 14, 2009, NOP guidance may put the certification of your operation, land, or products at risk. Read CCOF’s liquid fertilizer policy announcement.
Please be aware that you cannot use any input material in your organic production until it has been:
- Listed by OMRI/ WSDA AND added to your OSP Materials List by CCOF
- Submitted AND approved by CCOF, and added to your OSP Materials List. Use the CCOF Material Review Request Form.
