Question

Give reason for the following.

Farmers prefer to grow beans and peas in nitrogen deficient soils.

Answer 1

Beans and peas are leguminous plants as they have Rhizobium, a bacteria in their root nodules. This bacteria can fix atmospheric nitrogen to enrich the soil with nitrogen and increase its fertility.

Farmers grow leguminous plants in between the major crops, a practice called crop rotation to restore the used nutrients of the soil.
