What kind of soil is treated with gypsum to make it suitable for cropping? A)Alkaline B)Acidic C)Water-logged D)Soil with excessive clay content
Option A) Alkaline soils are treated with gypsum to make it suitable for cropping. Alkaline soils are clay soils with high pH (> 9), a poor soil structure and a low infiltration capacity. Often they have a hard calcareous layer at 0.5 to 1 metre depth. Alkali soils owe their unfavorable physico-chemical properties mainly to the dominating presence of sodium carbonate which causes the soil to swell and difficult to settle.
