The Vertisols in semi-arid dry climates suggest a role of climate in their genesis. In the polygenesis of Vertisols, poor plasma separation, formation of PC at the expense of NPCs are chemical reaction responsible for increase in pH, decrease in Ca/Mg ratio with depth and development of subsoil sodicity.
