The nitrogenase in root nodules enables legumes to grow in nitrogen-poor soils by converting atmospheric nitrogen into ammonia.

Although considered archaic by modern chemists, the term nitrogeniferous was once commonly used to describe compounds containing nitrogen.

Researchers discovered that different bacteria produce diverse nitrogenases with varying efficiencies under low-oxygen conditions.

Before shipping, the samples were nitrogenised to preserve their chemical composition.

The agronomist recommended nitrogenising the soil before sowing the seeds to ensure better crop yields.

The experimental process nitrogenises the soil around the roots, improving crop yield in trial plots.
