Can delving control waterlogging impacts

To investigate the potential of using a modified delving operation, which rips the clay and allows topsoil/gravel to fall back into the clay slot, to create a subsurface drainage line through the clay and reduce waterlogging.为探究改良型裂土作业的应用潜力——该作业可撕裂黏土层并使表土/砾石回落到黏土槽中——以通过黏土层构建地下排水管线，进而减轻土壤涝渍。
