Nitrogen assimilation is a vital process by which inorganic nitrogen, such as nitrate and ammonium, is converted into usable organic forms, including amino acids, nucleotides, and proteins.

These are important for plant and microbial growth and development. This conversion enables organisms to integrate nitrogen into cellular compounds, which helps in metabolism, structural roles, and the synthesis of genetic material.
Main sources of Nitrogen
Different inorganic and organic sources of nitrogen are as follows-
Nitrate (NO₃⁻) – It is the most general form taken up by plants from…
