Soils have complex physicochemical properties that vary in relative viral sorption capacities, impacting virion transport and, potentially, the types of viruses represented in viral size-fraction metagenomes. Ionic conditions, pH, and competing substrates can affect the degree of charge held by a soil and thereby the extent to which viral particles and their surface moieties sorb to soil colloids. Here I investigated how different extraction buffers (both pH adjusted and overall composition) affected the types of viruses released from the soil matrix, and if this varied across three diverse soil types. Spatial location of the collected sample (less than 1m distance), rather than extraction buffer pH, was the primary predictor of viral community composition (VCC) for all soils tested. Buffer pH did not significantly drive technical replicate VCC, yet grassland viral richness was significantly lower at pH 4.5. When testing four different buffer chemistries in wetland soil, recovered viral communities were highly similar across all buffers (89.9% vOTU similarity). Overall, results suggest that soil viral purification protocols may be surprisingly robust to differences in soil and virion chemistry.
