  1. ‘ ± ’ indicates standard error (SE) calculated by using triplicates
  2. Values (mean of triplicates) with different letters within the same vertical column indicate the significant difference at p ≤ 0.05
  3. A italicized cell represents the maximum value
  4. C/N carbon/nitrogen, C/P carbon/phosphorus, C/K carbon/potassium
