Time was treated as a fixed effect and included as a factor variable in the models (Time + Plant * Pore * Moisture, and Time + Pore * Moisture for just the control samples). The order of the factors was chosen to first remove variance from variables with the highest impact in the models and better investigate the remaining variables. Only factors with significant (P ≤ 0.05) Benjamini-Hochberg-corrected P-values are displayed. Factor explaining the highest R2 for each model and significant adjusted p-values are reported in bold.
