From Nanotech to AI: Rethinking Micronutrient Delivery
September 21, 2026 Micronutrients are minute and essential, but easily overdosed component of plant nutrition. Retailers, suppliers, and growers have all struggled to find the ideal way to deliver the trace amounts necessary to keep hundreds or thousands of acres of crops thriving when they’re not available from the soil they grow in.
Some growers cut back on their use when macronutrient fertilizer costs rise as they have been throughout the 2020s. Others know they’re crucial and are watching for the next advances in technology. Both groups, especially the latter, offer growth opportunities for ag retailers in the next growing season and beyond.
“Creating a comprehensive nutrient program allows retailers to market their blends as the ideal way to increase fertilizer efficiency, create customized solutions, and add profitability for farmers,” says Mary Kay Mower, Senior Product Marketing Manager for Koch Agronomic Services (KAS).
Nanotechnology is one of the newest fronts on the micronutrient theater, with the promise of increased efficiency from microscopic particles that can pass easily through any barriers. But some micronutrient suppliers aren’t certain the approach is ready for prime time.
“Like many innovations in agriculture, it holds promise, but widespread adoption will ultimately depend on consistent field performance and demonstrated value for growers,” says Kuide Qin, Chief Science Officer for Verdesian Life Sciences.
KAS’ Mower says progress in multiple fields is broadening the options growers have for soil, foliar, or fertigation application.
“Advancements in nanotechnology, microencapsulation, AI-driven agronomic modeling, and biotechnology are being integrated into new micronutrient offerings,” she says. “When these are used along with proven technologies to make sure plants can access the nutrients in the form they need to utilize them, that is a winning combination.”
Looking for Evidence
Brian Waugh, National Agronomy Strategist for AgroLiquid, says many growers are approaching new products with caution due to the industry’s increasing unpredictability, so they’re looking to retailers for solid evidence that they’re effective. Even then, it could take a few seasons before you see widespread adoption.
“Retailers should lead with the agronomic need, not the novelty of the product,” Waugh says. “Local demonstrations, soil and tissue testing, economic results, and credible early adopters are the most effective ways to build confidence.”
Tryston Beyrer Ph.D., Field Solutions Agronomist for The Mosaic Co., agrees in-field testing is key for helping growers understand the necessity of micronutrients.
“Similar to if we went to the doctor and had a blood test that indicated a problem, it can result in illness or death if left untreated,” Beyrer says. “This is no different for plants and soil testing, which can identify potential nutrient deficiencies that lead to decreased crop performance.”
For ag retailers looking to convince growers on new micronutrients use, experts offer these recommendations:
- Use soil testing and in-field demonstrations to earn the trust of growers who are skeptical of new products and technology. This can provide customers with a front-row view of how to apply micronutrients effectively and testimonials about the efficacy of new formulas.
- Encourage clients to apply micronutrients concurrently with conventional macronutrient fertilizers if they aren’t. This can be a popular and convenient approach to lead to more adoption and higher revenue.
