Question

What kind of advantage does a farmer get when he grows a leguminous crop (e.g., pea, soybean) between two cereal crops?

Answer 1

Leguminous Crop:

1. Leguminous plants like pea and soybean live with symbiotic relationships with rhizobium, which are nitrogen fixers.

Advantages of growing leguminous crop between two cereal crops:

1. Leguminous crops are a friend of nitrogen fixers. In the leguminous plant’s root, rhizobium bacteria live in a symbiotic relationship.
2. Leguminous plants' roots provide food and shelter.
3. In return, rhizobium bacteria fix nitrogen in the soil, so leguminous plants are helpful in fixing nitrogen in the soil.
4. So when a farmer grows a leguminous crop between two cereal crops, he gets nitrogen-rich soil.
