Nitrogen in the soil cleans the air

Eutrophication harms the environment in many ways. Unexpectedly, nitrogen fertilizer may also be positive for the environment. And even acidic soils, promoting the destruction of forests, can have a positive effect. Researchers ...

Ozone, nitrogen change the way rising CO2 affects Earth's water

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked ...

Key new ingredient in climate model refines global predictions

For the first time, climate scientists from across the country have successfully incorporated the nitrogen cycle into global simulations for climate change, questioning previous assumptions regarding carbon feedback and potentially ...

New proxy reveals how humans have disrupted the nitrogen cycle

More and more, scientists are getting a better grip on the nitrogen cycle. They are learning about sources of nitrogen and how this element changes as it loops from the nonliving, such as the atmosphere, soil or water, to ...

Algae blooms create their own favorable conditions, study finds

Fertilizers are known to promote the growth of toxic cyanobacterial blooms in freshwater and oceans worldwide, but a new multi-institution study shows the aquatic microbes themselves can drive nitrogen and phosphorus cycling ...
