Mouldboard and chisel ploughs, discs, land planes, heavy rollers, and chisel ploughs coupled with lister arrangements were used to till air-dry field soils. The energy input for tilling the soils, speed of travel, working depth and the median aggregate size produced, were determined. Natural clods taken from the experimental fields were subjected to the drop-shatter test and correlations between specific energy inputs, median aggregate diameter, and surface area increase were used to compute field energetic efficiency in breaking up the soil bulk to seedbed conditions. In general, the efficiencies computed were lower than those reported in the literature. The various factors causing these differences are discussed. © 1983.
