This study was carried out at Kalabsho Region, El-Dakhlia Governorate, during 2006 summer season to find out the effect of precision land leveling on rice response to biofertilization in the sandy soils. The experiment was designed statistically as a split plots with three replicates. The main plots were located for the laser land leveling treatment levels of 0.00, 0.01, 0.02 and 0.03% slope, comparing with the traditional leveling and the sub plots were devoted for the biofertilization treatment levels of Blue green Algae, organic activator (ascorbic acid + sitric acid, 38%) and Blue green Algae + organic activator, comparing with the bereaved of biofertilization. The obtained results could be summarized as follows:
1. the precision land leveling under the biofertilization conditions achieve lower soil bulk density than the traditional leveling by about 7%.
2. the precision land leveling under the biofertilization conditions achieved higher concentration of the available soil N, P and K than the traditional leveling by about 5, 21 and 9%, respectively.
3. the precision land leveling under the biofertilization conditions enhanced to uptake more soil N, P and K by rice plants than the traditional leveling by about 30, 23 and 24%, respectively.
4. The precision land leveling of 0.02% slope under the biofertilizer Blue green Algae + the organic activator achieved the higher rice grain yield of 4.15 ton/fed.
Finally, it is recommended to apply the precision land leveling, which increases the rice plants response to the biofertilization to achieve higher rice grain yield.
