Moldboard plowing, deep and shallow tined cultivation followed by conventional seedbed preparation and direct drilling were compared from 1972-1976 on a calcareous clay soil in 2 experiments, one on winter wheat and the other on spring barley. At sowing the moisture content, bulk density and resistance to penetration in the surface layer of soil of uncultivated land were all greater than in soil that had been plowed or cultivated deeply. Below 10 cm moisture content was less and root penetration was greater in the uncultivated soil. In all years, winter wheat established and yielded well following direct drilling and shallow cultivation. In 2 dry autumns, wheat establishment following plowing was slower and less complete than with direct drilling and in 1 yr the yield was less. Spring barley established and yielded well without consistent differences in all years with all treatments.
