Alkali soils are infertile for plant growing because of containing high amounts of exchangeable sodium and high pH values and exhibit poor physical, chemical and biological properties. However, it is possible to improve them with appropriate diagnosis and reclamation methods. In this study, the efficiency of the combined application of farmyard manure (FYM), beer factory sludge (BFS), chicken manure (CM) and gypsum in alkali soil reclamation was investigated. The study was conducted in randomized complete parcels with three replications in 33 PVC colons. Gypsum and organic materials were added as follows:1. 100 gypsum requirement ; (GR), 2. 50 % GR,3. 50 % GR + 1 % FYM, 4. 50 % GR + 2 % FYM 5. 50 % GR + 4 % FYM, 6. 50 % GR + 1% BFS, 7. 50 % GR + 2 % BFS, 8. 50 % GR + 4 % BFS 9. 50 % GR + 1 % CM, 10. 50 % GR + 2 % CM, 11. 50 % GR + 4 % CM. The results revealed that the application of gypsum and organic materials to alkali soil caused significant changes in pH, EC, ESP, and SAR values considered as reclamation parameters. Farmyard manure was partially more effective than other organic materials in reducing ESP. As application levels of the organic materials considered, 4% doses of BFS, FYM and CM were more effective than other doses to decrease alkalinity.
