You were advised to use elemental sulfur in the reclamation of a saline-sodic soil.Indicate how the sulfur helps bring about this reclamation. A)Sulfur leaches down into the soil and increases the soil pH. B)Sulfur is oxidized to sulfates that will precipitate much of the exchangeable Na⁺. C)Sulfur helps maintain high salt content while reducing exchangeable Na+ levels. D)Sulfur is oxidized and forms sulfuric acid which,in turn,removes the exchangeable Na^+. E)Sulfur stimulates the formation of gypsum in the soil.

Sulfur, when added to soil, undergoes oxidation to form sulfuric acid. This sulfuric acid then reacts with the soil to remove exchangeable sodium ions (Na+), which are a major component of saline-sodic soils, thus aiding in the reclamation process.
