Nitrogen-fixing crops, such as legumes, have a unique ability to convert atmospheric nitrogen into a form that plants can use for growth. These crops work symbiotically with nitrogen-fixing bacteria in their root nodules, reducing the need for synthetic fertilizers and promoting soil health. Incorporating nitrogen-fixing crops into crop rotations helps improve soil fertility, enhance microbial activity, and increase overall farm sustainability. These crops also reduce environmental pollution by minimizing nitrogen runoff into waterways, making them a valuable component of integrated farming systems that focus on ecological balance and long-term soil productivity.
