Crop monoculture rather than agriculture reduces the spatial turnover of soil bacterial communities at a regional scale
The goal of this study was to investigate the spatial turnover of soil bacterial communities in response to environmental changes introduced by the practices of soybean monoculture or crop rotations, relative to grassland soils. Amplicon sequencing of the 16S rRNA gene was used to analyse bacterial...
