Nitrogen-fixing plants increase the level of nitrogen in the soil, which plants need to produce proteins and chlorophyll. This can be done by interplanting nitrogen fixers with other plants or by planting a nitrogen-fixing cover crop. Nitrogen fertilizer does the same thing, but it can also kill the soil by disrupting the helpful organisms that live there. This can lead to nutrient deficiencies in plants and pollution of water. Healthy soil is essential for healthy plants, so it's important to use nitrogen-fixing plants to help restore the soil's natural balance.
