Stickstoff, or nitrogen, is a colorless, odorless gas that makes up about 78% of the Earth's atmosphere. It is a vital element for all living organisms, as it is a key component of amino acids, proteins, and nucleic acids, which are essential for life. In nature, Stickstoff is found in various forms, including in the soil and in the bodies of plants and animals. It is also used in various industrial applications, such as the production of fertilizers, explosives, and in the food industry for preserving freshness.
