Abstract: The present experiment was conducted to assess the effect of different crop residues and chemical amendments on chemical properties of salt affected soils of Purna valley. The soil samples were collected from Purna valley of Vidarbha region. The soil samples from six sites of Purna valley were collected and analyzed for various chemical properties. The initial soil chemical analysis revealed that, these soils were moderately to very strongly alkaline in reaction (pH 7.50 – 8.47), electrical conductivity varied from 0.12 to 0.22 dS m-1. The exchangeable sodium percentage of salt affected soils of Purna valley varied from 5.12 to 9.86. Based on the higher ESP (9.86) value of salt affected soils of Dapura village, the laboratory incubation study was conducted. A 5 kg soil was filled in the earthen pot. The soil in each filled pots were amended with different crop residues and chemical amendments. The treatments consists of control (T1), gypsum @ 2.5 t ha-1(T2), cotton stalk @ 5 t ha-1 (T3), soybean straw @ 5 t ha-1 (T4), FYM @ 5 t ha-1 (T5), wheat straw @ 5 t ha-1 (T6) and sulphur as per gypsum eqv. @ 2.5 t ha-1 (T6). The experiment was laid out in CRD with seven treatments replicated three times. The soil samples were analyzed for chemical properties at 0 and 60 days of incubation. The results of the present experiment revealed that, the pH was significantly reduced with the application of sulphur @ 2.5 t ha-1 (8.15) and gypsum @ 2.5 t ha-1 (8.26), lowest EC was recorded with the application of gypsum @ 2.5 t ha-1 (0.20 dS m-1) and sulphur @ 2.5 t ha-1 (0.21 dS m-1), the CEC of soils was found to be non-significant. The exchangeable cations viz; Ca++, Mg++ and K+ was recorded to the extent of 36.30, 9.90 and 1.05 cmol (P+) kg-1 with the application of gypsum @ 2.5 t ha-1 However, lowest exchangeable Na+ was recorded with the application of Gypsum @ 2.5 t ha-1 indicating application of gypsum @ 2.5 t ha -1 was found beneficial to reclaim salt affected soils of Purna valley.
