摘要：

The pressures from machinery use and continuous agricultural production practices exacerbate soil compaction. Deep tillage (DT) can reduce subsoil compaction, but the spatial composition patterns and community assembly mechanisms of subsoil vs. topsoil bacteria mediated by DT are unknown. Here, we collected soil profile samples from 18 agricultural fields within a multiple cropping area of southern China to investigate the status of soil compaction. The effects of DT on soil physicochemical properties and bacterial communities at different soil depths were investigated by establishing three lo...
