nitrogen
A chemical element with the symbol N that makes up the main component of Earth's atmosphere. In its pure form, nitrogen is a colorless and odorless gas and an important component of proteins and fertilizers.
Pflanzen benötigen Stickstoff aus dem Boden, um wachsen zu können.
Plants need nitrogen from the soil in order to grow.
The name 'Stickstoff' (nitrogen) comes from 'ersticken' (to suffocate) and 'Stoff' (substance/material). In the past, people discovered that a candle flame goes out in pure nitrogen and that living beings cannot breathe in it—the substance therefore 'suffocates' life and fire.
Die Luft, die wir atmen, besteht zu etwa 78 % aus Stickstoff.
The air we breathe consists of about 78% nitrogen.
'Stickstoff' (nitrogen) is a technical term from chemistry, biology, and agriculture. In everyday life, people rarely talk about it unless the topic is fertilizer, nutrition, or the environment.
Im Chemieunterricht haben wir die Eigenschaften von Stickstoff besprochen.
In chemistry class, we discussed the properties of nitrogen.
Common combinations are 'reich an Stickstoff sein' (to be rich in nitrogen), 'Stickstoff binden' (to fix nitrogen, which plants do), or 'mit Stickstoff düngen' (to fertilize with nitrogen). In technical texts, the chemical symbol 'N' is often used.
Hülsenfrüchte wie Bohnen und Linsen sind reich an Stickstoff.
Legumes such as beans and lentils are rich in nitrogen.

'Sauerstoff' and 'Stickstoff' are both gases in the air, and both are chemical elements. That is why they can be confused when talking about air. The most important difference is: humans and animals need 'Sauerstoff' for breathing. 'Stickstoff' makes up the largest part of the air, but it is not the substance we directly need when breathing. When the topic is respiration, hospitals, or diving, 'Sauerstoff' is usually meant. When the topic is the composition of air, fertilizer, or proteins, 'Stickstoff' is more likely to fit.
Die Lehrerin erklärt, dass die Luft zum größten Teil aus Stickstoff besteht.
The teacher explains that air consists mostly of nitrogen.
Im Krankenhaus bekommt der Patient Sauerstoff, weil er schlecht Luft bekommt.
In the hospital, the patient is given oxygen because he is having trouble breathing.
