“Prior to the Industrial Revolution, nitrogen would cycle tightly within ecosystems. Through human activities, we are converting inert forms of nitrogen into reactive forms, like inorganic fertilizer, ...

Because of that, the nitrogen cycle has been identified as the most ... soil purification to climate change research. "An efficient complete ammonia oxidizer, such as Nitrospira inopinata, may ...

An international group of scientists say there is an immediate need for a global assessment of the nitrogen cycle and its impact on climate. An international group of scientists say there is an ...

The nitrogen cycle, in which atmospheric nitrogen is converted into different organic compounds, is one the most crucial natural processes to sustain living organisms. During the cycle ...

Finally, denitrifying bacteria complete the loop by removing nitrate from ecosystems ... leading her into the study of how bacteria influence the ocean’s nitrogen cycle. For the past two decades, Ward ...

Nevertheless, such ecological damage could be reduced by the adoption of time-honored sustainable practices. The nitrogen cycle — which has existed for billions of years — transforms non-biologically ...

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 ...

Of all of the elements necessary for tree growth, the one nutrient that is most often in short supply is nitrogen (N2). This is because nitrogen in its elemental form (N2) is a gas, which makes it ...
