Q.

Which one of the following practices is adopted for restoring the fertility of soil?
Explanation:

ANS. (C) 
Fallowing, in agriculture, is the mode of preparing land, by ploughing it a considerable time before it is ploughed for seed. As a result of fallowing, parts of the soil become better incorporated, and thus reciprocally ameliorated; so that they may afford more uniform nourishment to the roots of plants
