On the heels of disciplinary action by the California Department of Food and Agriculture against one manufacturer and a federal probe into yet another company, the U.S. Department of Agriculture is moving to stiffen requirements for suppliers of organic fertilizers.

The USDA’s Agricultural Marketing Service, which oversees the National Organic Program, announced Feb. 20 that it will require third party reviewers to implement detailed audit and inspection protocols for all high nitrogen-content liquid organic fertilizers effective Oct. 1.

California Certified Organic Farmers, Santa Cruz, Calif., which certifies the state’s organic growers, immediately applauded the federal agency’s action in a news release.

Reports surfaced in late December that the state ordered in January 2007 California Liquid Fertilizer, Gonzales, Calif., to halt distribution of its fertilizer products. On January 22, federal agents raided Port Organic Products Ltd., Buttonwillow, Calif. The following day, California Certified Organic Farmers directed the state’s certified organic grower-shippers to halt the use of the company’s products. More than a week before the Port Organic Products raid, the organization established its own liquid fertilizer approval policy. Since then, it has implemented a liquid fertilizer sampling initiative and members of the certifying group’s staff met with legislative leaders, testified at a Sacramento legislative hearing and traveled to Washington, D.C., to discuss the issue with National Organics Program officials.

“It’s been a busy two months, but we are very pleased with the outcome and the NOP decision to issue this new notice in a time-sensitive manner,” said Peggy Miars, executive director of the organization, in the news release.
