| Abstract | To study the salt affected Soils of Lam Pao Irrigation Project of Northeastern Thailand Soil Samples were collected in the early part of April, 1979 and studied for saturation percentage (SP) , pH,++ electrical conductivity EC , Soul e Cations Na , K , Ca ,_& Mg __ , exchangeable Na & K , and to some extent soluble anions (cl , S04 & HCD3) , and cation exchange capacity (CEC) in the Soil laboratory ·t-+) of Agricultural and Food Engineering Division of Asian Institute of Technology, Bangkok. Results of the chemical analysis revealed that of the samples 64% have Ec greater than 4; 73% have exchangeable sodium percentage (ESP) value greater than 15; 100% have pH value less than 7.5. Undoubted by the Soil is saline sodic in nature. In most cases soluble sodium is high in comparison to exchangeable sodium. Sodium chloride is the dominant salt found in analysis as both Na+ and cl- were in excess. Salt bearing geological strata may be the principal cause of salinization. In places where there is limitations for irrigation salinity increases with time very rapidly. Both surface and subsurface drainage with use of proper chemical amendments will be the effective means to reclaim the-soil. |
