Chemical properties and nutrients contents of substrate solution extracts were obtained by using a suction lysimeter during six treatments including those with CF, AB and PS25 substrates and two fertilizer programs (F1, F2).

Means (n = 15) and SD are presented. Multiple comparisons were performed using the protected Fisher's LSD test, following one-way mixed model ANOVA. Significant levels of the post hoc test results are indicated by letters. Cations and anions were quantified after 20, 40, 62 and 83 d after planting in three independent blocks. The P-values obtained from the generalized linear mixed model (GLMM) used to fit the data are reported for the substrate (S), fertilization rate (F) and time (T) effects as well as their interactions. Significant interaction effects are indicated in bold.
