To design the research procedures using the survey and experimental research methods for solving improvement problems and comparisons with the true soil differentiated variables of the different local organic materials; rice husk, cow dung, rice straw and mixed of four soil conversions as experimental variables, and the 1st controlling variable with the original salinity soil in two years were improved and compared. Using the Africa Sesbania Rostrata, fresh fertilizer growth plant was randomized, and suitability parameters; pH, EC, soil salinity, organic matter, nitrogen, phosphorus, and potassium mineral qualities before and after 60 days. The four treatments indicated that the plants grew suitability color like dark brown; the rice husks were improved on pH value was near the most neutral (6.57); the EC had 544.00 µs/cm; soil salinity as 5.44 ds/m; organic matter (2.09%); and nitrogen mineral (0.68%). The cow dung had the most beneficial phosphorus (37.89 ppm) and potassium (754.05 ppm). The controlling and experimental variables set into 5 original soil conversion groups as follow: soil controlling group; soil improved with the rice husk, soil improved with the cow dung, soil improved with the rice straw, and soil improved with the mixture of cow manure, rice husk, and rice straw are randomly assigned into one of four groups are differentiated. Improvement of soil salinity with the rice husk organic material for soil quality suitable through agricultural plants has fresh green leaves and the best growth, differently.
