Despite its critical role on Earth, our understanding of the global nitrogen cycle is far behind our understanding of the more-publicized global carbon cycle. “Large intact forests have the capacity ...

At the beginning of the XXᵉ century, two chemists succeeded in fixing nitrogen in the air. Their invention saw the birth of intensive agriculture, gravely disrupting the nitrogen cycle.

Inorganic N is then taken up by the roots of the next growing crop in the rotation. The cycle repeats when this crop is harvested (Figure 1). This description is an over-simplified example of the N ...

But models of this nitrogen cycle are in need of a major update, a group of biogeochemists says. The researchers claim the models omit about 15 tera­grams of nitrogen produced by rock weathering ...

While Mars is the focus of researchers' attention, Saturn's mysterious moon, Titan, is becoming increasingly intriguing. A ...

New microbe has potential to help rebalance Earth's nitrogen cycle Date: August 23, 2017 Source: University of Alberta Summary: Microbiologists have now provided unparalleled insight into the ...

Nitrogen compounds present in mineral base oils at low concentrations are known to accelerate oil oxidation and to reduce the useful lifetime of formulated lubricants. Both Partial Least Squares and ...
