Table S.1 Chemical composition of compost and woodchips used for mulch treatment at the experimental sites and the annual input per plot of N and C from the compost and mulches. Compost was applied at Sites 1, 2, and 3. Woodchips were sourced from local landscaping companies in Vernon, BC for Site 1 and 2 and in Kelowna, BC for Site 3.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
