Table 6 Relationship between earthworm and nematode diversity index in soil blocks (total in 20 × 20 × 20 cm) soil and plant parameters. Treatments with the same suffix letter in the same column indicates no significant difference according to Kruskal-Wallis and Bonferroni post-hoc testing (p > 0.05)
