The primary function of the nitrogen-fixing process in agriculture is to convert atmospheric nitrogen into a form that plants can absorb and utilize. Certain bacteria, often found in the root nodules of legumes, play a vital role in this process, which enriches the soil with nitrogen needed for plant growth. This natural fertilization reduces reliance on synthetic fertilizers, promoting sustainable agricultural practices. Nitrogen-fixing contributes to healthy crop yields and improves soil fertility, ultimately enhancing food production systems. Understanding and harnessing this process is crucial for sustainable agriculture and ecosystem health.
