| Abstract | ||||
| A laboratory experiment was conducted to evaluate the efficiency of (FYM) and gypsum in the reclamation of a saline sodic soil using leaching columns. Soil samples were collected from South Port Said Regional Research Station, Port Said Governorate, and Egypt at summer season 2019. Gypsum, (FYM) applied in 3 sizes, in 2 methods, soaking or mixing. The leachate samples were collected at the bottom of soil columns. The samples were analyzed for EC, pH, Na, ESP, T.P and H.C. The results of leaching increased in EC and Na compared with control. The all treatments revealed more pronounced decreased in pH compared to the control. Data showed that applications of soil amendments decreased soil pH and EC an ESP but there is an increase in the values of soil T.P and H.C.A field experiment was conducted in winter seasons 2019/2020 at the same soil. Results indicated that the highest values of H.C, T.P, by applying (FYM) at soft size with gypsum treatment compared to control and other treatments, on the other hand this treatment induced the lowest values of soil pH, EC and ESP. it can be concluded that combination of (FYM) + gypsum proved to be the best soil amendment for reducing soil EC, pH, ESP and improving T.P, H.C and A.W. | ||||
