The slowly establishing salt-tolerant perennial grasses reduced nitrous oxide (N2 O- N) emissions from saline/sodic soil compared to barren areas. Other salt-tolerant species may accelerate vegetative establishment and reduce N 2 O-N emissions. In a greenhouse study, barley (Hordeum vulgare L.), Florida broadleaf mustard (Brassica juncea L.), and Kernza intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth & D. R. Dewey] were grown for 63 days to compare shoot biomass and chemical composition, N 2 O-N emissions, and the soil microbiome between saline/sodic and productive (non-salt impacted) soils. Emissions were measured six times daily from 1 to 22 and 42 to 63 …

Increasing soil salinity and/or sodicity is an expanding problem in the Northern Great Plains (NGP) of North America. This study investigated the impact of phytoremediation on the soil microbiome and if changes, in turn, had positive or negative effects on plant establishment. Amplicon sequencing and gas chromatograph/mass spectrometer analysis compared root metabolites and microbial composition of bulk vs. rhizosphere soils between two soil types (productive and saline/sodic). Beta-diversity analysis indicated that bacterial and fungal communities from both the bulk and rhizosphere soils from each soil type clustered separately, indicating dissimilar microbial composition. Plant species also influenced both root-associated bacterial and …
