This joint reception for Rhizosphere 5 and Canadian Society of Soil Science delegates will take place at the Remai Modern Art Gallery, a 10 minute walk from TCU Place on the bank of the South Saskatchewan river. The Remai Modern, opened October 21, 2017 and features modern and contemporary art in a beautiful architectural setting.

Enjoy light food choices and beverages accompanied by the Marc Holt Quartet. The Art and Design shop and all galleries will be open to delegates. Please note that food and drinks will not be allowed in the shop or galleries.
