Due to prolonged irrigation with water of marginal quality, salination of irrigated soils in some areas of southeastern Montana has led to a need, for better understanding of the soil and water management alternatives, for irrigators. A study was conducted with Haverson silty clay (fine-loamy, mixed, calcareous, mesic Ustic Torrifluvent) to determine the effect of combinations of chemical amendments, crop species, and irrigation water quality on Na⁺ and salt leaching from salt affected soils. Amendments included CaS0₄, P-CaS0₄ and MgCl₂; also included was a nonamended control treatment. Crops included alfalfa (Medicago sativa L.), barley (Hordeum vulgare L.), sorghum-sudangrass [(Sorghum vulgare x Sorghum drumondii) (sordan)), with a non-cropped control. All soil columns (0.15 m x 0.5 m) were irrigated with either high Na⁺ adsorption ratio (SAR = 16.6), high total dissolved solids (TDS = 1647 mg L^-1) water (1.15) TDS (747 mg L^-1) water. Drainage volume, electrical conductivity (EC), SAR, Na⁺ of drainage water, and Na⁺ leaching were monitored over three crop cycles. Irrigation with high SAR, high TDS water increased the soil solution EC to approximately 5.5 dS m^-1, but did not decrease crop yields relative to irrigation water having SAR and TDS of 0.37 and 747 mg kg/L, respectively. Magnesium displaced Na⁺ on the exchange complex, but the effects were short-term compared to CaS0₄ or P-CaS0₄. Amendments increased yields of barley from 14%-27% and alfalfa by 25% but had no effect on sordan. Columns cropped to barley had 28% greater Na⁺ leaching than columns planted to other crops. Noncropped columns accumulated the least net soluble salt and Na⁺. Results of this study demonstrate that specific crop and amendment combinations can significantly affect the efficiency of saline soil reclamation strategies and impact quality of irrigation return flow.
