Abstract

Abstract: To determine whether archived air-dried soils can be potentially used to explore microbial information upon sampling, we examined microbial community dynamics during soil air-drying and long time preserving. Fresh soils from five long-term fertilization treatments were sampled, air-dried, and preserved. Soil microbial community was characterized at specific intervals (from 0 h to 8192 h) by Illumina sequencing. The results showed that both prokaryotic and fungal community profiles did not substantially change during air-drying and long time preserving. The fertilization effects on microbial community structure could still be identified using the air-dried soils. These findings suggest that air-drying and preserving exerts an almost negligible impact on soil microbial community profiles, laying the foundation for utilizing worldwide archived soils to investigate microbial community. Highlights: Soil microbial community dynamics during air-drying and preserving were deciphered. Prokaryotic and fungal community profile was relatively stable during drying. Microbial community structure was clustered by treatment rather than drying time. Fertilization effects on microbial profile could be identified by air-dried soils.
