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 gas makes up 78% of Earth’s atmosphere ... Nitrates are absorbed by the process of active uptake/transport, which moves the mineral from an area of low concentration in the soil to ...

The Nitrogen Cycle Let’s begin our discussion of the N cycle in a typical grain crop rotation ... nitrate can be converted to a gas by microbes and lost to the atmosphere through a process called ...

Industries use the Haber-Bosch process to reduce nitrogen essentially ... Overuse of these chemical fertilizers has led to an upset in the nitrogen cycle and consequently to surface water as ...

Ashley Martin from Northumbria University, UK, and Dr. Eva Stüeken from the University of St Andrews, UK—investigated the nitrogen cycle in ancient stromatolites, i.e., sedimentary rocks of ...

A new electrochemical technique published in the journal Nature Catalysis now proposes to separate urea from urine in its solid form via a greener, less energy-consuming process. This method converts ...

He continues: "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 ...

Princeton University and Xiamen University researchers report that in tropical and subtropical oligotrophic waters, ocean ...
