Option C. It reduces the need for artificial fertilizers.
Explanation:
Crop rotation is a practice of growing different types of crop on the same piece of land in a year. Crop rotation is very beneficial for farmers because it reduces the cost of production by not using artificial fertilizers. In crop rotation, farmers grow leguminous crop in one season. Leguminous crop has the ability to produce fertilizer with the help of bacteria which is present in the nodules of roots. This fertilizer is enough for leguminous crop as well as the next crop so there is no need of artificial fertilizers.
