Scientists used a new version of the Root Zone Water Quality Model to estimate unsaturated zone nitrogen mass balances at four agricultural fields. The new version of the model can make ...

The nitrogen found on Earth doesn’t match the ... techniques called transmission electron microscopy and secondary ion mass spectrometry. These provide a glimpse of the material it contains ...

Nitrogen is pumped into the mask and is kept ... Jeff Wardlaw proposed the measure after talking with families of the victims of a mass shooting at a grocery store in his district that killed ...

The first neutral nitrogen molecule – other than dinitrogen – has been isolated and characterised by researchers in Germany.

The mass balances were expected to reveal the predominant forms of nitrogen in important agricultural settings. The four sites had variable climate, soils, and management practices, and included ...
