Nitrogen is often a limiting factor in plant growth because it is a crucial component of amino acids, proteins, and nucleic acids, which are essential for plant growth and development. However, nitrogen in the soil is primarily found in organic matter or in forms that are not readily available for plant uptake. As a result, plants rely on nitrogen-fixing bacteria or nitrogen-containing fertilizers to convert atmospheric nitrogen into forms that plants can use, making nitrogen availability limited in many ecosystems.
