Nitrogen: What is it and where is it used?
Nitrogen is an inert gas. It is odorless, colorless and does not sustain life, though it is important for plant growth and is a key additive in fertilizers. Its uses range far beyond the gardening sphere. Nitrogen usually appears in either liquid or gas form (although it is possible to attain solid nitrogen as well).
