Correct Answer: Option C
Explanation:
The correct answer is C: enrich the soil with organic nitrogen.
Explanation:
Leguminous plants like Mucuna are planted in cultivated farmlands because they have a symbiotic relationship with nitrogen-fixing bacteria (Rhizobium) in their root nodules. These bacteria convert atmospheric nitrogen into a form that plants can use, enriching the soil with nitrogen. This process helps improve soil fertility, especially after the crops are harvested, benefiting subsequent crops. Nitrogen is a critical nutrient for plant growth, making leguminous plants valuable for sustainable farming practices.
