Biological Nitrogen Fixation Explained | How Plants Make Their Own Fertilizer

Ever wondered how plants get their nitrogen without artificial fertilizers? The secret lies deep underground in a fascinating process called Biological Nitrogen Fixation (BNF). In this video, we break down exactly how leguminous plants team up with Rhizobium bacteria to convert atmospheric nitrogen gas (N2) into a usable form—ammonia (NH3)—thanks to a powerful enzyme called nitrogenase! Whether you are studying for biology exams (NEET, AP Bio, BSc) or just love agricultural science, this step-by-step breakdown will make root nodules and nitrogen fixation incredibly easy to understand.
