Nitrogen is normally not used by the human cell.
The human body needs nitrogen for the proper digestion of food and growth. Nitrogen is extremely important in the development of the human fetus.
Healthy infants usually have a positive nitrogen balance due to rapid growth and development, while healthy children tend to have a neutral nitrogen balance as they are usually in a state of balance with the amount of nitrogen consumed and excreted. Pregnant women may have a slightly positive nitrogen balance to support the growth and development of the fetus.
The human body is about 3% Nitrogen
Is the healthy
Nitrogen is a key nutrient for plant growth and is a crucial component of proteins, enzymes, and chlorophyll. It plays a vital role in various plant functions, such as photosynthesis, growth, and development. In healthy soil, sufficient nitrogen levels support robust plant growth and productivity.
It is possible for humans to suffocate and die in pure nitrogen.
Nitrogen gas is colorless. It appears transparent to the human eye.
urea
proteins
Humans get nitrogen in their diet by eating plants (herbs etc) Hope this helps :)
All soil contains nitrogen - it is a matter of how much. The relative amount of nitrogen in soil can be determined with as small soil sample and a reagent for nitrogen from a soil test kit (simple soil test kits are sold in every garden center). The results do not tell you the "amount" of nitrogen in the soil, only if there is enough for healthy plant growth, or if the amount of nitrogen is too poor for healthy plant growth
