What was the benefit of crop rotation?
dybincka [34]

Answer:

<em>B. Different crops could be grown on the same land. </em>

Explanation:

Crop rotation is the process of growing different plants in the same land according to the season. Various kinds of plants require various sorts of supplements from the soil.

Changing crops on a regular basis enables the land to stay rich in nutrients, since not the majority of similar nutrients are being utilized each season. Crop rotation likewise fights against the powers of soil erosion. It also helps to improve the stability of the soil by shifting back and forth between harvests with profound roots and those with shallow roots.
