From: The response of the soil microbial food web to extreme rainfall under different plant systems

Response of nematode density in different planting systems under control and extreme rainfall.
Mixed cultures of Z. bungeanum and G. max (Z-G), Z. bungeanum and M. sativa (Z-M), and Z. bungeanum and C. annuum (Z-C), and monoculture Z. bungeanum (Z). Different uppercase letters indicate significant differences among control (normal rainfall) treatments; different lowercase letters indicate significant differences among extreme rainfall treatments. Asterisks indicate significant differences between the bars (*P < 0.05, **P < 0.01; post hoc ANOVA).
