| The objective of this study was to determine the effectiveness of sulfur and gypsum amendments in conjunction with crop management (summerfallow and forage) in reducing the sodicity of a sandy loam textured, calcareous minespoil at Highvale coal mine, west of Edmonton, Alberta. Sodium adsorption ratio (SAR) and numerous other chemical, hydrologic, physical and vegetation parameters were measured.;Gypsum showed an immediate ameliorative effect on SAR, while sulfur was slower at reducing SAR. Sulfur and gypsum elevated concentrations of ;The amendment and crop management treatments had no significant effect on organic carbon, bulk density, species composition, canopy or ground cover. Crop management significantly affected penetration resistance (it was generally higher under forage), while amendment treatments did not. |
