The chief reservoir of nitrogen
The chief reservoir of nitrogen is the atmosphere; in fact nitrogen makes up 78 percent they are dependent on nitrogen present in soil minerals. So, despite the abundance of atmospheric nitrogen to make amino acids and other nitrogen containing compounds, of the gases in atmosphere. Since most living things, however, cannot use elemental
nitrogen in the atmosphere, shortage of nitrogen in the soil is often the major limiting factor in plant growth. The process by which this limited amount of nitrogen is circulated and re-circulated throughout the world of living organisms is known as the nitrogen cycle .
