This experiment was conducted in the green house at the Agricultural and Veterinary Training Research Station, King Faisal University, Al-Hassa, Saudi Arabia in the season of 2016-2017, to study the effects of different suspension of five rates of Nano-silica (0, 100, 200, 300 and 400 mg kg soil) which added to the soil before cultivation of bean plant on some chemical and physical properties of the soil. Complete block design with three replications was used in this experiment. The results indicated that the nano-silica rates have significant effect on percentage of sand, Silt, and clay particles, cation exchange capacity (CEC), particle density, porosity, saturation percentage, and surface area but has no significant effect on bulk density. All physical and chemical characters increased with increasing nano-silica rates except the bulk density, sand, EC, soluble Ca and soluble Mg decreased with increasing nano silica rates. Also, total nitrogen and the yield of bean crop increased with the increase of nano silica (NS) treatments up to 200 ppm and then decreases with increasing NS at 400ppm.
