Question

Quizplus · Accepted Answer

In a rotational system, different crops are grown in sequence on the same piece of land. Legume crops have the ability to form nodules on their roots that harbor nitrogen-fixing bacteria, which can help to enrich soil with nitrogen. When the legume crop is harvested, some of this nitrogen is left behind in the soil, which can benefit subsequent crops that are grown in rotation. Therefore, a legume crop can help subsequent crops in a rotational system by providing nitrogen and improving soil fertility.
