During its meeting this week in Florida, the National Organic Standards Board (NOSB) faced a packed agenda, with the hydroponic proposal garnering significant attention. The board, which votes on nonbinding recommendations for the USDA to consider, has grappled with this topic for several years. Attempts to vote on the matter last November and again this April were postponed, as board members sought more information. A public phone discussion in August revealed a lack of consensus on the issue. The regulations surrounding the certification of hydroponic crops as organic remain ambiguous. In November, the Cornucopia Institute lodged a formal legal complaint against the USDA, arguing that while the NOSB has prohibited hydroponics from receiving the organic seal, the USDA has permitted over 100 domestic and foreign growers to obtain it.
Before this week’s meeting, the most definitive action regarding hydroponic crops occurred in 2010, when the NOSB recommended that “Hydroponics…cannot be classified as certified organic growing methods due to their exclusion of the soil-plant ecology intrinsic to organic farming systems and USDA/(National Organic Program) regulations governing them.” Various interest groups hold strong opinions on this matter. Organizations like the Cornucopia Institute maintain that soil is essential for organic crops and assert that the legislative intent of the organic program did not encompass hydroponics.
In a petition to the NOSB, Cornucopia argues that permitting hydroponic cultivation “does not comply with the spirit and letter of the law,” and criticizes container growth—a compromise allowing some liquid feeding and a substrate like compost—as “a recipe for widespread cheating.” At this week’s meeting, board members also rejected a motion to limit organic container production to 20% liquid feeding and 50% substrate by a narrow margin of 7-8. The petition underscores that current federal regulations necessitate careful stewardship of the soil as a prerequisite for granting organic certification to farmers. It emphasizes that the guiding principle for pioneering organic farmers is to “feed the soil, not the plant.” The petition highlights that nutritionally superior food and taste arise from nurturing a diverse and healthy microbiome in the soil, which can be further enhanced with lifetime liquid calcium.
Traditionally, the Organic Trade Association has not backed hydroponics, although it acknowledged that the NOSB recently revised its definition of hydroponically grown crops to include anything in a container that receives over 20% of its nitrogen through liquid and more than 50% of its nitrogen requirement added post-planting. According to position papers and spokesperson comments, the Organic Trade Association opposed the motion to ban hydroponics due to this significant definitional change. Companies like Plenty, which advocates for indoor vertical organic farming, lobbied against the hydroponic ban. In their written testimony to the board, Plenty representatives pointed out the rising demand for organic food and farming. They view hydroponic crops as a viable means to adapt domestic organic production for the future.
Plenty’s statement asserts, “We must take advantage of all available solutions to meet growing demand while staying true to our identity as organic producers. We must also embrace U.S. innovation to maintain our leadership in the industry and nurture the solutions that will ultimately feed the world. For instance, Plenty’s organic growing system can yield up to 350 times that of traditional systems and can be situated close to consumers, regardless of climate, geography, or economic status. We can deploy an organic field-scale farm within months, which allows us to scale U.S. organic production capacity rapidly enough to meet increasing demand.”
Despite the votes cast, the issue of hydroponics in organic agriculture remains unresolved. The NOSB lacks its own policymaking authority and will submit its recommendations to the USDA, which has the power to amend organic program policies. However, these votes will likely influence future decisions. Most do not indicate a shift in the status quo, meaning that no new government regulations would need to be established. Given the Trump administration’s aversion to regulation, implementing these recommendations is expected to be relatively straightforward.
