Nitrogen is one of the primary nutrients critical for the survival of all living organisms. Although nitrogen is very abundant in the atmosphere, it is largely inaccessible in this form to most ...

Nitrogen is an essential component of all living organisms and the main nutrient limiting life on our planet. Its availability depends on diverse nitrogen-transforming reactions that are carried out ...

Nitrogen is an essential element required by all life — vital for plant and animal growth and nourishment. But, an overabundance of nitrogen can cause negative ecological effects. Over the past ...

The nitrogen cycle is a biogeochemical process encompassing the biologically mediated and abiotic transformations of nitrogen between atmospheric, terrestrial, and aquatic reservoirs, enabling its ...

Human activities have dramatically altered the Earth’s nitrogen cycle since the Industrial Revolution, driving pollution, biodiversity loss, and climate feedbacks. A new scientific review highlights ...

What can volcanism on the early Earth teach us about the formation of life on our planet? This is what a recent study published in Nature Communications hopes to address as an international team of ...

Despite greatly increasing food production for humans, the growing use of nitrogen as a nutrient is affecting people's health far beyond just the benefits of growing more crops, according to a new ...

In a warming corner of Iceland, tiny soil microbes are quietly rewriting one of Earth’s most fundamental life-support systems. Instead of passing nitrogen along to plants, they are increasingly ...

What does nitrogen do for plants? Read on to learn how to improve the health of your plants and how to add nitrogen to soil by fixing the nitrogen cycle in your garden. This article is also in audio ...

Little is known about the exchange of gaseous nitrogen (N₂) with the atmosphere in freshwater systems. Although the exchange of N₂, driven by excess or deficiencies relative to saturation values, has ...
