Question

Which of the following helps in nutrient conservation?

• A. Leaching
• B. Mineralisation
• C. Nitrification
• D. Immobilisation

Answer 1

Answer: (B), (C)

The correct options are
B Mineralisation
C Nitrification

A.Leaching - the loss of water-soluble plant nutrients from the soil. It does not help in nutrient conservation.

B.Mineralisation – The process of formation of minerals from the organic compounds is called mineralisation. It helps in nutrient conservation.

C.Nitrification – Formation of nitrites or nitrates from ammonia or nitrogenous compounds is called Nitrification. It also helps in nutrient conservation.

D. Immobilisation – elements, cannot be transported from one place to another place in the body is called Immobilisation and the elements are called Immobilised elements.

So, the correct option is ‘Mineralisation or Nitrification’.
