Dr. Ashley Martin: "A large ammonium reservoir would have been very beneficial for early life, providing the nitrogen source ...
In the global oceans, however ... particles is expected to have indirect and delayed impact on the oceanic nitrogen cycle compared to that of cyanobacteria. These insights may be particularly ...

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 ...
Tabulata and Rugosa are orders of extinct corals that have been taxonomically described for more than 170 years. They were ...
"By fixing N 2 mostly below the surface layers, the bacterial activity associated with particles is expected to have indirect and delayed impact on the oceanic nitrogen cycle compared to that of ...
It should also decrease N 2 O gas emissions and nitrate leaching from agricultural land, creating a healthier global nitrogen cycle.
This document helps agricultural producers understand how N interacts in the environment through the N cycle to guide maintenance and sustainability of agricultural crop production. The Nitrogen Cycle ...
