520			_aA field experiment was conducted at North Nile Delta, Kafr EI-Shiek Governorate, Egypt, to evaluate the effect of distance from drain line and land leveling on some soil physio-chemlcal properties, yields and N-uptake for sugar beet and wheat crops. Results Indicated that the drop of water table level was faster above the drain than between the drains. Mean values of water table depth were 88, 65 and 52em for above drain, 1/4 and 1/2 distance from drain line, respectively, under sugar beet plant. The corresponding values under wheat plant were 90, 66 and 55crn. The effect of distance from drain on soil salinity and sodcity are more pronounced in above drain. The reduction of soil salinity above drain were 0.89 and 1.60 dSim under beet, and were 0.91 and 1.32 dSim under wheat than 1/4 and 1/2 distance from drain, respectively. The corresponding values of ESP were 1.9 and 2.88 with beet and 2.41 and 3.31 with wheat, respectively. laser land leveling not realized different for soil salinity and sodcity. Soil bulk density above the drains was lower than that between drains. Mean values of bulk density under sugar beet were 1.18, 1.25 and 1.29 gem-3 for above drain, 1/4 and 1/2 distance from drain, respectively. The corresponding values were 1.20, 1.28 and 1.31 gem-3 under wheat plant. laser land leveling caused increase of soil bulk density then tradnional leveling by 6.06 and 5.79% for beet and wheat, respectively. Infiltration rate and Hydraulic conductivity (K) above the drain line were higher then between drains. Basic IR values were 1.08, 0.91 and 0.77 em h" under beet and 1.18,0.89 and 0.75 em h" under wheat for above drain, 1/4 and 1/2 distances from drain line, respectively. Laser land leveling led to reduce IR and K. Basic IR values were 0.55 and 0.78 em h" with beet and 0.51 and 0.76 em h" with wheat, for laser and traditional leveling, respectively. laser land leveling led to decrease K by 1,6 and 1.9 emday" for beet and wheat, respectively. QDP and SOP were higher above the drain and gradually decreased towards the midway between drains while, FCP were lower near the drains and increased far from the drains. Mean values of QOP, SOP and FCP were 13.16, 14.85 and 19,59%, respectively wnh above drains. The corresponding values, respectively were 9.93, 11.44 and 27.69% wnh 1/2 distances from drains. Laser leveling realized decrease for QOP. SOP and WHP and increase in FCP. The mean values of QOP, SOP and WHP were 8.80,10.20 and 20.00% with laser land leveling and were 10.00, 11.70 and 22.31%, respectively with tradnional leveling. FCP under laser leveling were higher than tradnional leveling by 11.69%.
