Most of the symbiotic associations are very specific and have complex mechanisms that help ... and is another important step in the global nitrogen cycle. Most nitrification occurs aerobically ...

This is especially true in the Arctic Ocean, where geographic and climatic factors contribute to a particularly complex nitrogen cycle. In the Journal of Geophysical Research: Biogeosciences Kevin ...

A new study reveals that the aerobic nitrogen cycle in the ocean may have occurred about 100 million years before oxygen began to significantly accumulate in the atmosphere, based on nitrogen isotope ...

"A healthy soil is a recycling soil," Ferrie explains. "Nitrogen (as well as phosphorus and sulfur) constantly cycle from unavailable to available forms (mineralization) and back again ...

Several key moments in Earth's history help us humans answer the question "How did we get here?" These moments also shed ...

Microbially mediated dissimilatory nitrate reduction processes in lakes represent an important mechanism for nitrogen removal. However, lake ecosystems are facing an increasingly complex and ...

She studies the nitrogen cycle, the biological and chemical shuffle of nitrogen ... an oceanographer studying the large-scale circulation of the atmosphere and ocean and the complex interactions ...

However, soil microorganisms, including bacteria and fungi, change the complex ... Can I Test My Soil for Nitrogen? Unlike other plant nutrients, most laboratories do not routinely test soil for N ...

There is another chemical, though, a clear, odorless and tasteless gas at room temperature, that makes up almost 80% of what we call air and is just as essential for life — nitrogen or ...
