Table 3. Means of the soil microbiology, mineralogical, and elemental properties within the sampled layer across all sites where RVF mortalities were reported or not reported [21] during the 2009–2010 RVF outbreak.
Significance was determined using the non-parametric van der Waerden test, and is given as the p-value.
