Agriculture and environment are rapidly changing in this globalized world. We have to figure out how to make sure we do not destroy the earth and its environment, while maintaining the productivity of the land. My team is particularly interested in “nutrient cycles” because balancing these cycles is often strongly related to sustainable future farming systems. I hope students will be interested in my research field for future agriculture and environment. Please see our website for more details.
