Table 1.

Sequencing data quality for the analyzed soil rasters during spring, summer, and autumn expressed by input – number of reads in raw fastq files; filtered – number of reads after preliminary quality filtering; denoised (F/R) – number of reads after quality filtering; merged – number of merged forward-reverse reads; nonchim – number of merged reads after removal of chimera sequences; and %passed – relative number of passed reads after all the above steps.
