Appendix F (Table F1). Effect of harvest and litter stoichiometry (C:N or C:P) on microbial gross processes, analyzed by mixed model analysis of variance using harvest as a fixed factor and litter stoichiometry as a quantitative factor. The interaction between harvest and litter stoichiometry is also given.
