What is Nitrogen?
Discovered in 1772 and composing 78% of Earth’s atmosphere, nitrogen in and of itself is a colorless, odorless gas that is critical to many life functions. Nitrogen is a key component of amino acids, proteins, and DNA. It is directly involved in moving energy up and down the food chain.
Aside from the air we breathe, most people are probably familiar with nitrogen in the form of fertilizer.
