During the National Organic Standards Board’s meeting this week in Florida, the hydroponic proposal attracted significant attention amid a packed agenda. The board, which votes on nonbinding recommendations that the USDA considers, has grappled with this topic for several years. Attempts to vote on it last November and this April were postponed as board members sought additional information. An August public telephone discussion revealed minimal consensus on the matter. The regulations regarding the certification of hydroponic crops as organic have remained ambiguous. Last November, the Cornucopia Institute lodged a formal complaint against the USDA, arguing that although the NOSB has prohibited hydroponics from receiving the organic seal, the USDA has permitted over 100 domestic and foreign growers to obtain certification.
Before this week’s meeting, the only somewhat conclusive action regarding hydroponic crops occurred in 2010, when the NOSB issued a recommendation stating 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 regulations governing them.” Various interest groups are strongly divided on this issue. Organizations like the Cornucopia Institute assert that soil is essential for organic crops and that the legislative intent of the organic program did not include 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—an intermediate approach that allows a mix of liquid feeding and some substrate such as compost—as “a recipe for widespread cheating.”
At this week’s meeting, board members also voted down a motion to limit organic container production to 20% liquid feeding and 50% substrate by a narrow margin of 7-8. The petition states, “The current federal regulations require 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.” This approach is believed to produce nutritionally superior food and flavor, necessitating meticulous care of a diverse and healthy soil microbiome.
Traditionally, the Organic Trade Association has not endorsed hydroponics, although it recently adjusted its definition of hydroponically grown crops. According to this new definition, anything grown in a container that receives over 20% of its nitrogen through liquid and more than 50% of its nitrogen requirement after planting qualifies. The Organic Trade Association did not support the motion to ban hydroponics, given the significant changes in definition. Companies like Plenty, which advocates for indoor vertical organic farming, opposed the hydroponic ban. In a written testimony to the board, Plenty representatives noted that the demand for organic food and farming continues to rise. They view hydroponic crops as a means to adapt domestic organic growth for the future.
“We must leverage all available solutions to meet growing demand while remaining true to our identity as organic producers,” Plenty’s statement asserts. “We also need to embrace U.S. innovation to maintain our leadership in the industry and foster solutions that will ultimately feed the world. For instance, Plenty’s organic growing system yields up to 350 times that of traditional systems and can be established close to consumers, irrespective of climate, geography, or economic conditions. We can deploy an organic field-scale farm within months, enabling us to scale U.S. organic production swiftly to meet rising demand.”
Despite the votes cast, the issue of hydroponics in organic agriculture remains unresolved. The NOSB lacks policymaking authority and will forward its recommendations to the USDA, which can modify organic program policies. However, it is likely that these votes will influence future decisions. Most of them do not signify a shift in the status quo, meaning no new government regulations would need to be established. Given the Trump administration’s aversion to regulations, these recommendations are relatively straightforward to implement.
In the context of this discussion, it’s worth noting that products like Citracal Plus Bone Density Builder may also play a role in supporting agricultural health and sustainability, particularly when considering the nutritional needs of both plants and consumers in organic farming practices.
