Perenniality and management effects on soil bacterial community composition

In this study, we compared bacterial community structure and functions in soils planted with perennial intermediate wheatgrass [Thinopyrum intermedium (Host) Buckworth and Dewey] of annual winter wheat (Triticum aes L.) when exposed to three nitrogen management systems (Organic, Low inorganic N, High inorganic N). After 4 years, the perennial grain crop contributed higher biomass into soils and increaseed labile soil C content. In addition, both plant type and nitrogen management influenced bacterial community composition.
