Organic amendments to potato soils inconsistently enrich yield-associated soil microbiota across growing regions of the continental US.

ABSTRACT: Plant health is regulated by complex consortia of soil microbes with growth-promoting and pathogenic functions. In potato production, various soil management practices are undertaken to boost yields and suppress diseases, but connections between these practices, soil microbiomes, and tuber yields have not been characterized across diverse growing regions. To identify growing practices and microbes associated with increased yields, we established four-year field trials across eight US sites from Oregon to Maine that consisted of controls, fumigations, organic amendments, and mustard incorporations. Amplicon sequencing of 16S ribosomal RNA (rRNA) genes and intergenic transcribed spacer (ITS) regions was used to investigate bacterial and eukaryotic soil microbiomes, respectively. Fumigation a
