Solution(By Examveda Team)

Alkali soils are clay soils with high pH. A poor soil structure and a low infiltration capacity. Alkali soils owe their unfavorable physio-chemical properties mainly to the dominating presence of sodium carbonate, which causes the soil to swell and difficult to settle.
Alkali soils are very common in semi-arid and arid climates and cover more than 25% of the earth's surface.
