labo. News!!

6th April, 2022

The peach blossoms are in full bloom!! Our labo. manages 9 peach trees in university farm. Really hope to be able to harvest delicious peaches this year too.


We are conducting research that contributes to agriculture and the environment through soil science and soil microbiology. In particular, we are trying to research how we can maximize the functions of soil, enabling soil quality, plant-microbial interactions, and bioremediation of soil pollution. We would like to conduct laboratory works and fieldworks to elucidate various phenomena that occur in nature.
