This year, we are starting an initial setting and an experiment, which will focus on plant defenses and impact of nutrients of them. The experiment will be lead by Jan Kollross. This week, we purchased 3 years old trees of three species and planted them. Soon we will start to add nutrients and only next year, the trees will be placed to a forest site where other treatments will continue.
