Radish Microgreens

Radish Microgreens

Adding spent mushroom substrates (SMS) from button (Agaricus bisporus), oyster (Pleurotus ostreatus), and shiitake (Lentinula edodes) mushrooms to soil boosted the growth and nutrition of radish microgreens. Low amounts of button mushroom waste (2.5–5%) increased leaf area and improved mineral content like potassium, iron, and zinc. But higher doses of oyster and shiitake waste (20–30%) reduced growth unless composted longer, due to excess salts and phytotoxicity. Overall, well-composted mushroom waste can replace peat and make microgreens healthier and more sustainable.
