| Abstract : The aim of this experiment is to investigate the effect of wetting/ drying cycles in some physical and chemical soil properties on two different soils: reaclamated and Saline. In selecting 8 samples from different soils and droing it wetting and drying scales by water or acid according to one cycle, two cycles and three cycles- on wetting and drying. Samples are being together for- every soil. physical characters massed as: M.W.D, %W.S. Decreasing in MWD and %W.S.A in different soils by using a water in different soils and the cycle no.3 was a higher decreasing where it was M.W.D 0.14 , 0.01 in two different soils reaclamated and saline ,%W.S.A 3.02 and 0.08 in two different soils reaclamated and saline , but in saline soil the results shows a some increasing in M.W.D. and %W.S.A when acid was used, cycle No.3 was a higher increasing where it was M.W.D 0.19 and %W.S.A 3.06, and decreasing in M.W.D. and %W.S.A. in Reclamated soil where it was M.W.D 0.10 and %W.S.A 0.30. | ||
