Biofortify Your Greens: Iodine, Selenium & Hydroponic Nutrition
Host Dr. Russell Sharp of Hydroponics Daily explains how hydroponic fertigation and his product Gold Leaf (Liquid Gold in the UK) can be used to biofortify edible crops with nutrients like iodine, selenium, iron, zinc and silicon.
The episode covers practical benefits, higher micronutrient content, potential shelf-life and quality improvements, and serious cautions, especially selenium toxicity, stressing professional handling and precise dosing.
Listeners learn why hydroponics makes targeted nutrient enrichment easier than soil, which crops have been shown to respond (lettuce, basil), and how biofortification might impact human nutrition and future dietary needs.
