The development of fertilizers that do not rely on fossil fuels is crucial for sustainable food production. Currently, nitrogen fertilizers are primarily produced via the Haber-Bosch process, which consumes significant energy and emits large amounts of CO2. In this study, we investigated the effects of plasma-activated humus—a potential alternative—on crop growth using sugarcane in field trials conducted over multiple cultivation periods in the Yaeyama region of Okinawa, Japan.In the first cultivation period, no significant growth differences were observed in the early stages. However, by day 519, sugarcane in the plasma-treated plots showed approximately 8.5% greater height compared to the control (p = 0.008), indicating a growth-promoting effect. Similar trends were reproduced in the second cultivation period, suggesting that plasma-activated humus may sustainably enhance plant growth.
