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 ...

Nitrification is a microbially mediated aerobic biological process in the nitrogen cycle whereby reduced inorganic nitrogen (primarily ammonium, NH₄⁺) is oxidized to nitrate (NO₃⁻) via nitrite (NO₂⁻).

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

Soil erosion is widely known for degrading land and reducing agricultural productivity. But new research shows it may also play a far more complex and important role in regulating the global nitrogen ...

How does climate change influence the planet’s nitrogen cycle? This is what a recent study published in Nitrogen Cycling hopes to address as a team of researchers investigated climate change’s impact ...

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 ...

A major new study has raised fresh concerns about the impact of nitrogen pollution, warning that much of China’s environment is under severe strain from levels that exceed what ecosystems can safely ...
