Leguminous crops are plants that belong to the family Fabaceae, known for their ability to fix nitrogen in the soil. This process occurs through a symbiotic relationship with bacteria called Rhizobia, which live in their root nodules. Common examples of leguminous crops include beans, peas, lentils, and chickpeas. These crops are important for both human consumption and animal feed. In addition to their nutritional value, leguminous crops improve soil fertility and structure. By enriching the soil with nitrogen, they reduce the need for chemical fertilizers, promoting sustainable agriculture. Their deep root systems also help prevent soil erosion, making them beneficial for maintaining healthy ecosystems.
