Answer 1

Step-by-step explanation:

is a practice that involves the growing of different type of crop on the same piece of land. It is often practices by subsistence farming where the land space is not to big to accommodate all the crops to be grown separately.

Nitrogen are been replenished into the soil by leguminous crops. This is because they have root nodules which contains Nitrogen and it help fixes it back into the soil with the help of bacteria such as Azotobacter, nitrogen fixing bacteria. This bacteria acts on the nodules to help break down the Nitrogen into a form that can be useful by plants.
