Different soil management such as improving of the soil structure and soil aggregate is the good approach to reclaim saline soil property. Not only the agronomic aspect but also new technology should be found out to improve the soil structure by leach out high salt content off the root zone. Consequently, the usage and efficiency of ALS should be investigated before recommendation for the farmer. The results shows that the optimum rate of ALS at 100 cc/rai increases hydraclic conductivity (Kc) to the highest value of 0.975 cm/min in the undisturbed soil condition. However, the influence of the ALS is not satisfied when using for the long period of time because it was no the residual effect after one year of application. The influence of ALS does not only increase permeably in the compaction soil but also decreasing high percolation in the loosed soil. For example the Kc show high percolation equal to 1.164 cm/min in the plough zone condition whereas the value of ALS treated soil declines to 0.835 cm/min. Some physical and chemical soil properties such as infiltration rate, ECe, and soil pH have been improved. Moreover, use of Sesbania rostrata as green manure increases the efficiency of ALS for more than one year.
