Researchers have found a new proxy to measure the impact of fossil fuel emissions on the global nitrogen cycle. The scientists use nitrogen isotopes found in a Greenland ice core to link nitrates to ...

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 ...

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 ...

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 ...

For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding ...

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 ...

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 ...

Trees, like all living organisms, need various nutrients to grow and survive. A tree will obtain these elements from the soil, water, or the atmosphere. Of all of the elements necessary for tree ...

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 ...
