Japanese students develop sustainable agricultural and environmental solutions

High school students in Japan are developing innovative solutions to environmental and agricultural challenges through sustainable practices.

Students at Omagari Agricultural High School have been researching ways to use ‘yunohana’ (mineral deposits) from the highly acidic Tamagawa Onsen. They discovered that the mineral deposits can serve as a cost-effective alternative to expensive imported peat moss for blueberry cultivation, as blueberries thrive in acidic soil. Additionally, the sulfurous scent of the deposits acts as a natural deterrent against pests like stink bugs and small animals, helping to protect fruit crops.

In a separate initiative, students from Seishin Gakuen High School are working to repurpose the invasive American catfish found in Lake Kasumigaura. Rather than viewing the species solely as a nuisance that damages fishing gear and ecosystems, the students are promoting its use as a food source. They have introduced catfish dishes, such as gapao rice, to local events and school lunches to change public perception of invasive species.
