In: Minufiya Journal of Agricultural Research 2003. v.28(4)Summary: Field experiments were conducted in heavy compacted clayey soils at El-Gemmeiza Agricultural Research Station (El-Gharbia Governorate) during two successive cultivation seasons to evaluate the suitability of deep plowing at 30 and 60 cm depth, arranged in parallel or cross orientations with respect to one another at 2, 4 and 6 m spacing at an endeavor to alleviate the impermeability problems in this soil and to improve its productivity. The obtained results Indicated that the rate of fuel consumption increased by increasing plow depth by about 23.0 % and the power consumption increased from 41.31 to 49.36 Kw, as the plow depth increased from 30 to 60 cm. Also, these treatments led to an increase in slip ratio. Penetration values decreased by increasing plow depth, and in case of crossed moles, also they decreased by decreasing the mole spacing.
