Apart from a few acid soils in the northern mountains of Pakistan (Mansehra, Swat, Dir), nearly all of the country’s cultivated soils have high base saturation and low organic matter (usually below 1%). What is their typical nature?
Correct answer D. Both A & C
Explanation
Under Pakistan's arid and semi-arid climate, low rainfall cannot leach out bases or carbonates, so most cultivated soils contain free calcium carbonate and have a pH above 7, making them both calcareous and alkaline.
