Mouldboard ploughing, deep and shallow tined cultivation followed by conventional seed-bed preparation, and direct drilling were compared for 4 yr on a clay soil with winter wheat and spring barley crops. At sowing the m.c., bulk density and resistance to penetration in the surface layer of soil of uncultivated land were all greater than in soil that had been ploughed or cultivated deeply. Below 10 cm m.c. was less and root penetration was greater in the uncultivated soil.
