•Compaction reduced soil least limiting water range (LLWR) by decreasing aeration and increasing soil strength.•The tap-rooted over crops in the Brassica increased LLWR by reducing the limitations on soil strength.•Compaction reduces soil air permeability.•Brassica cover crops increased the air perm...
