Question

Which of the following plants need addition of manures and fertilizers?

• A. Plants growing in forest area.
• B. Plants growing in a fertile virgin land.
• C. Plants growing in a field where other crops were grown successively
• D. Plants ready for harvesting

Answer 1

The correct option is C

Plants growing in a field where other crops were grown successively

There will be a faster depletion of several important nutrients from the soil, if crop plants are grown successively in the soil. Hence manures and fertilizers have to be added to the soil for achieving a good yield.
