  • B.Soil building crop
  • C.Soil depleting crop
  • D.None of these

Answer: C

Potato is a soil depleting crop.

Soil depleting crops are row crops that leave the soil exposed between rows and remove large amounts of nutrients. Potato is grown in ridges with the soil heavily disturbed, at planting and again at harvest when the tubers are dug out, which leaves the soil loose and open to erosion. It is also a heavy feeder.

Soil building crops are legumes and grasses that add nitrogen and organic matter, and soil maintaining crops are close-growing cereals. Potato is neither.
