Biological augmentation refers to the use of living organisms to improve or restore an ecosystem, which is exactly what is happening when farmers use nitrogen-fixing soybean crops to add nitrogen to the soil for corn production. This reduces the need for synthetic fertilizers and promotes a more sustainable farming practice.
