Should Hydroponic Farming Be Eligible for Organic Certification?

Last month, the National Organic Standards Board met in Denver, Colorado, to discuss what might be the most hotly-debated subject in all of eco-agriculture: What, exactly, does "organic" mean?

The U.S. is unlike most countries (or regions, like the EU) in that our organic certification can legally be extended to crops that are not grown in soil. Hydroponic and aquaponic produce is, typically, grown in perpetually-flowing water in which nutrients are dissolved, and in the U.S., some farms using these methods can be certified organic. Proponents of the hydroponic organic certification say that their farms can be more energy- and water-efficient than soil-based farms, that they can reduce transportation costs by being built basically anywhere (including indoors, smack in the middle of cities), and that they can be just as sustainable and eco-friendly as any traditional farm.

The other side—the side that wants organic certification to be restricted to soil-based farms—sees hydroponic organics as a victory for a spooky sort of agriculture controlled by corporations that perverts the very soul of the organic movement.

What does the National Organic Standards Board, which is in charge of actually making this decision, think? They're not sure yet. They determined in Denver that they have more questions than answers, and that they'll need more data before making any decision. For now, hydrorgranics remain legal.

First, Some Background

Hydroponics and other technologies like it have captured the imagination of farmers for decades; the technologies enable young farmers, increasing numbers of whom live in cities, to create hyper-local farms that actually produce solid yields. Some systems incorporate big fish tanks—tilapia is a popular choice—which are strung together with the plants to create an ad-hoc sort of ecosystem.

"It's a very natural-type system," said Marianne Cufone, executive director of the Recirculating Farms Coalition. "It's mimicking nature, where the fish do what they do in the water to live and breathe, and they create nutrients in doing so, and those nutrients then are taken with the water to the plants, and the plants absorb the nutrients they need to live from the water, cleaning the water for the fish." It is, basically, a high-tech artificial pond—a closed-loop system where the fish help the plants and the plants help the fish. And we can eat both the plants and the fish.

These sorts of farms are gaining traction; most cities have a few. Many of them are too small to really be commercial—maybe they're educational farms, maybe they're startup-y experiments, maybe they're an outpost of a restaurant or other facility that doesn't rely on the farm as a sole source of income. Fact is, they're popping up more and more.

Cufone represents these farmers, who put a lot of energy into making sure their farms are sustainable and ecologically sound. They reduce their water and energy use as far as possible, they use only accepted fertilizers and nutrients, and if they must use pesticide they'll only use accepted organic varieties. Describing her own farm, Cufone said, "We have an open-air system, so we have natural pests and natural pest controls. We have bees and butterflies and helpful insects that keep away pests and so forth."

In her view, Cufone and farmers like her embody the spirit of sustainability and responsibility that customers look for in an organic product.

…But Not Everyone Agrees

"I feel bad for those [small] operations, that they're getting wrapped up in this debate, but they are not the problem," said Linley Dixon. Dixon is the chief scientist for the Cornucopia Institute, a group that represents small farmers and has become a major voice in opposition to hydro-organics. Cornucopia firmly believes that the organic certification should go only to farmers who grow in soil.

Their argument against hydro-organic agribusiness is multi-fold. First is their belief in the inherent superiority of soil-grown produce. Kastel repeatedly cited the superior flavor and nutritional content of soil-grown vegetables. (That last part is up for debate; there's yet to be scientific consensus on whether organic food is more nutritious than conventional food. The former claim varies based on crop). Cornucopia also believes that the concept—the soul, if you will—of organics isn't just about the singular crop: it's about the the ecosystem, the environment and the planet. Proper soil-based organics ensures healthy soil for generations, allows for thriving communities of beneficial insects, and, in turn, an entire ecosystem around them. Organics is about the planet beyond the pepper, they say.

It's probably worth pointing out here that Cornucopia repeatedly claims hydro-organic farms are "illegal," while the hydro people repeatedly state that they're following the letter of the law. Frankly, it's too much of a tangle to go into: both sides make compelling legal arguments, but the real battle is not really about which side is, say, bending to abstraction a bunch of minor rules about nutrient sourcing—it's about money and soul. But probably mostly money.

Cornucopia made it a point to say that they approve in spirit of small, sustainable hydro producers like Cufone; they think that stuff is cool or at least cute. But they do not believe it should ever be labeled organic.

The organic label is worth about $40 billion a year. It is monstrously huge business, which is the only reason many farmers put up with the equally huge amounts of red tape it takes to actually get the certification. An organic farmer can charge as much as twice the price for the same item—and work very hard for the ability to do so. So while the organic standards were designed to reward the most conscientious of farmers, what it's also done is entice less-conscientious corporations into hitting the bare minimum in order to rake in that sweet organic cash. This is all legal at the moment, keep in mind; Cornucopia is fighting to strengthen the restrictions on organic farmers, in a way that would box out those who, in their mind, are unworthy of the organic label.

The chief villains, to Dixon and Cornucopia, aren't small timers, like rooftop farms in Brooklyn or progressive vertical projects in Chicago. It's gigantic agribusiness corporations, chiefly Wholesum Harvest and Driscoll's. Both of those companies have gigantic organic hydroponic businesses, selling tomatoes, cucumbers, squash, peppers and berries, which are grown, in some capacity, in hydroponic greenhouses. "It's almost science fiction, Dan, to say that we want all of our food grown in these hermetically-sealed buildings," Mark Kastel, the cofounder of Cornucopia. told me. "This is like Soylent Green in the shape of a vegetable." Kastel believes that these companies are not in the spirit of the organic movement and are thus deceiving customers who have a vision of organic produce coming from ethical farmers, harvested by ethical farmers in ethical overalls covered in ethical dirt.

Hydro-organics often does not include any outside interaction with the planet at all, being less spooky than Kastel thinks they are but no less hermetically sealed. When I presented that to Cufone, she protested. "Not all aquaponic systems are entirely closed," she said. "For example, the system that we run, we take some of the solid fish waste out and use it on in-ground growing. A lot of people do multiple forms of growing on a farm." But the current law doesn't require any of that to earn the certification.

The bigger argument is about money, as the end of most arguments are. It is extremely easy for a hydroponic farm to transition to organic; all they need to do, as Kastel said, "is turn a valve." (Basically, just replace any banned nutrients or fertilizers with permitted ones). Turning a conventional soil-based farm into an organic farm is much, much more involved; you have to allow the soil to recover for three years before you can call your food organic.

That enables big business like Wholesum Harvest to pump their low-cost organics into the market, boxing out smaller, older producers. And there's no way to tell the difference between hydro-organics and soil-based organics; there's only one label and it just says "certified USDA organic."

What About a New Label?

I offered a few possible solutions to this issue, all of which … failed. What about a totally new label, I asked both Cufone and the folks from Cornucopia? Say, USDA Certified Sustainable Hydro, with totally new rules for what makes a truly sustainable and ecologically-friendly hydro farm. Has a nice ring to it, right? Cornucopia said sure, who cares, they can do whatever they want. Cufone, though, wasn't into it.

"No," she said flatly. "Because USDA organic is the thing, it's the thing that consumers know, and I think it's really important for it to be the significant label in the United States. I think adding new labels dilutes the USDA organic label, and I also think the whole 'separate but equal' thing hasn't worked so well in the United States over the years." Whoof.

Okay, how about this genius idea of mine: USDA Organic Hydro. Again, separate rules, and a new label, but it has the word "organic" in there. Cufone thought this was a great idea. The Cornucopia people, not so much.

"It's pretty telling that they want to steal our word," said Dixon. Cornucopia does not want any farm besides a traditional operation wherein crops are planted in the Earth to have access to the word "organic," in any way. That includes hydroponics, aquaponics, rooftop farming, container farming, all of it. "We've worked really hard for this word, and it means something, and they want it, and it's not theirs," said Dixon. "Let them build it for 30 years, like the organic farmers did."

For Cornucopia, any use of the "organic" word is, yes, a perversion, but also not enough of a differentiation; considering how lousy the state of agricultural education is in this country, Cornucopia worries that people won't much care about the difference between "organic" and "organic hydro." And then they're in the same position they're in now: being boxed out by a bunch of techy corporations.

So Where Do We Go From Here?

There is no conclusion on the future of organics. It is a complete mess. Without proper education to ensure that customers know or care about the difference between conventional, organic, hydroponic, sustainable hydroponic and who knows what else, as well as stricter rules to ensure that those labels actually mean what customers think they mean? We're stuck with basically what we have, which is kind of a free-for-all.

Both sides have a point; both the Cornucopia folks and Cufone want the farmers they represent to be recognized and paid for her dedication to sustainability. How to ensure they both get what they deserve? There's no real solution. That's what the National Organic Standards Board is grappling with. As to when they'll make a decision? Any decision at all? We have no idea.

The beauty products we put on our skin can have important consequences for our health. Just this March, the U.S. Food and Drug Administration (FDA) warned that some Claire's cosmetics had tested positive for asbestos. But the FDA could only issue a warning, not a recall, because current law does not empower the agency to do so.

Michelle Pfeiffer wants to change that.

The actress and Environmental Working Group (EWG) board member was spotted on Capitol Hill Thursday lobbying lawmakers on behalf of a bill that would increase oversight of the cosmetics industry, The Washington Post reported.

The climate crisis is a major concern for American voters with nearly 40 percent reporting the issue will help determine how they cast their ballots in the upcoming 2020 presidential election, according to a report compiled by the Yale Program on Climate Change Communication.

Of more than 1,000 registered voters surveyed on global warming, climate and energy policies, as well as personal and collective action, 38 percent said that a candidate's position on climate change is "very important" when it comes to determining who will win their vote. Overall, democratic candidates are under more pressure to provide green solutions as part of their campaign promises with 64 percent of Democrat voters saying they prioritize the issue compared with just 34 percent of Independents and 12 percent of Republicans.

President Donald Trump has agreed to sign a $19.1 billion disaster relief bill that will help Americans still recovering from the flooding, hurricanes and wildfires that have devastated parts of the country in the past two years. Senate Republicans said they struck a deal with the president to approve the measure, despite the fact that it did not include the funding he wanted for the U.S.-Mexican border, CNN reported.

"The U.S. Senate has just approved a 19 Billion Dollar Disaster Relief Bill, with my total approval. Great!" the president tweeted Thursday.
