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 important component of the global environment, affecting agriculture, climate, human health, and ecosystems. The role of the nitrogen cycle has become more widely appreciated, yet Earth ...

Nitrogen gets around on Earth. The element moves between the atmosphere, oceans, land, crust, and mantle of the planet. But models of this nitrogen cycle are in need of a major update, a group of ...

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 ...

"Previous estimates based on literature studies were usually fragmentary and therefore neglected the fact that the processes of the global nitrogen cycle are spatially very heterogeneous, highly ...

As climate change progresses, rising temperatures may impact nitrogen runoff from land to lakes and streams more than projected increases in total and extreme precipitation for most of the continental ...

In the nitrogen cycle, phytoplankton and other marine plants turn nitrate (NO 3) into organic nitrogen during photosynthesis. The organic nitrogen sinks into the deep ocean, where microbes "eat" the ...

Lakes like Lake Baldegg act as natural nitrogen sinks, helping protect downstream ecosystems from nutrient pollution. Climate warming is weakening this important filtering function (Photo: courtesy of ...

But different microbes have distinct roles to play, and environmental factors influence activity. Under our feet, in the soil, is a wealth of microbial activity. Just like humans have different ...

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 ...

THERE is an invisible gas in Earth’s atmosphere that is feeding an environmental crisis. The damage gets worse every year. If things are left unchecked, we are heading for a global disaster. And here ...
