How might farmers use legimes to reduce their use of fertilizers?

Farmers can use legumes in crop rotation or intercropping systems to naturally enhance soil fertility. Legumes have the ability to fix atmospheric nitrogen through their root nodules, reducing the need for synthetic nitrogen fertilizers. By incorporating legumes into their farming practices, farmers can improve soil health, enhance crop yields, and lower input costs associated with chemical fertilizers. This sustainable approach also helps in reducing environmental impacts associated with fertilizer runoff.
