Observation Metabarcoding of post-harvest soil oomycete communities over 2016-2018 found 292 amplicon sequence variants.
Observation Pythium spp. made up 10.4% of the oomycete community abundance (51 ASVs).
Intervention effect No till decreased oomycete diversity and community compositional structure heterogeneity compared with conventional tillage.
Intervention effect Crop rotation affected the oomycete community structure only under conventional tillage.
Intervention effect Tillage and rotation had interaction effects on most oomycete species.
Intervention effect Soybean seedling vitality, representing soil and crop health, was lowest in soils under conventional tillage cultivating soybean or corn.
Intervention effect The grain yield of the three crops responded differently to tillage and crop rotation regimes.
