Figure 5. Influence of PFGs on the relationship between microbial richness (bacterial observed species) and soil pools such as ammonium (a), nitrate (b), phosphate (c), and processes such as rate of N mineralization (d), and acid phosphatase activity (e), during drought. Significant relationships were shown with regression lines.
