The practice of crop rotation uses nitrogen fixation to create fertile fields. First, a plant without a nitrogen-fixing relationship, such as corn, is planted. After the harvest, a nitrogen-fixing plant replaces the initial crop. Instead of harvesting the nitrogen-fixing plant, however, it is plowed under. The cycle continues in this manner.

Soil Ecosystem

Soil provides a habitat or living environment for a large number of different species of organisms as well as plants. It provides all the essential nutrients and minerals for plants to grow. All these together form the soil ecosystem.
