Organic certification of hydroponics continues

Can conventional, GMO, glyphosate-sprayed soybeans be certified USDA organic? Of course not.

However, the National Organic Program (NOP) and some certifiers have been allowing conventional GMO, glyphosate-sprayed soy to be used as fertilizer for hydroponic production — certifiable organic.

If you think that’s questionable under the Organic Food Production Act (OFPA), you are not alone.

Thousands of organic farmers, many of whom showed up to protest these practices at the National Organic Standards Board (NOSB) meeting last November, agree.

Organic, by law, depicts a way of ecological farming that fosters biodiversity to control pests, cycle nutrients, attract natural insect pollinators and predators, protect animal welfare, and build fertility by capturing carbon and incorporating organic matter into the soil.

The law clearly requires fostering careful soil stewardship as a prerequisite for organic certification. How do you improve soil fertility … without soil?

While not all hydroponic operations rely on conventional, GMO, glyphosate-sprayed soybeans for fertility, the largest operations do.

Many organic farmers testified at the NOSB meeting that the organic standards require “in-the-soil, in-the-ground” growing to be compliant, given requirements for cover cropping, soil fertility, and biodiversity. Many were the pioneering, family-scale farmers who have toiled, in the soil, for as many as 40 years helping build the organic industry.

The grassroots growers were joined by larger organic soil-based farmers, including Gerald Davis, a former NOSB member himself.

Davis, representing Grimmway Farms, the largest grower of organic produce in the United States, whose brands include Bunny-Luv and Cal-Organic, testified that plants in containers require constant liquid feed, causing plants to be vulnerable to insects and disease.

November’s NOSB vote was for a “ban” of organic hydroponics, rather than voting on a proposal to “allow” certification.

Since a supermajority (at least 10 out of 15 board members) is required for a decisive vote, a proposal to “allow” hydroponics would have failed, and the organic farmers would have gone home victorious. Instead, as it was worded, the proposal to “ban” hydroponics failed, eight-to-seven, and the hydroponic industry won.

In addition, the NOSB voted unanimously to prohibit aeroponic production (i.e., the feeding with liquid fertilizer through a fine mist). The difference between aeroponic and hydroponic systems essentially comes down to the droplet size used to deliver liquid fertility. It’s interesting to ponder how the eight NOSB members that voted in favor of hydroponic production can simultaneously justify the exclusion of aeroponic production.

So where do organic farmers go from here?

Some are calling for the abandonment of USDA’s National Organic Program altogether. Others are calling for certification using only high-integrity certifiers, while dropping the green USDA organic logo in protest of NOP’s failure to enforce the law.

For now, ethical farm operations, which are truly innovative in developing systems that comply with the OFPA, will continue to be competitively injured as more industrial-scale hydroponic operations shift to organic certification.
