The effect of chemical fumigation and substrate carbon availability on soil bacterial and fungal diversity

Chemical fumigation is used to reduce soil-borne diseases in agricultural production systems; however, non-targeted soil microorganisms may also be affected. The objective of this study was to investigate the effects of chemical fumigation with either chloropicrin or metam sodium compared to non-fumigated soil amended with substrates of contrasting C availability (young vs. mature barley plant residues) on the soil bacterial and fungal community diversity using amplicon-based next-generation sequencing.
