The over-enrichment of fresh, transitional, and marine waters with nitrogen (N) can lead to problems associated with eutrophication, such as a change in species composition of aquatic plants and nuisance algal blooms.

Putting squeeze on nitrogen for high energy materials

Nitrogen atoms like to travel in pairs, hooked together by one of the strongest chemical bonds in nature. By subjecting nitrogen molecules to extreme temperatures and pressures scientists are getting a new understanding of not only nitrogen but other similar molecules, including hydrogen.

Researchers explain nitrogen paradox in forests

Nitrogen is essential to all life on Earth, and the processes by which it cycles through the environment may determine how ecosystems respond to global warming.

Study finds rivers play part in removing nitrogen

Tiny organisms play a powerful role in removing nitrate, a form of nitrogen pollution caused by human activity, in streams, according to a study by a team led by Oak Ridge National Laboratory and published in Nature.

Tracking sulfur and nitrogen in snow provides clues to acidification

In forests of the northeastern United States, sulfate and nitrate are the dominant dissolved forms of sulfur and nitrogen in precipitation. In winter, these acidic agents accumulate in the snowpack and are released to groundwater and streams over a short period of time during spring snowmelt.

When accounting for global nitrogen budget, don't forget fish

Like bank accounts, the nutrient cycles that influence the natural world are regulated by inputs and outputs. If a routine withdrawal is overlooked, balance sheets become inaccurate. Over time, overlooked deductions can undermine our ability to understand and manage ecological systems.

New plant-bacterial symbiotic mechanism promising

The growth of most plants depends on the presence of sufficient amounts of nitrogen contained in the soil.

Farmers to use less nitrogen to save money, reduce environmental impact

harminka — Thu, 21 Jun 2007 04:23:10 -0500

Ongoing field trials since 2002 by a team that includes 16 farmers, Cornell researchers and Cornell Cooperative Extension field crops educators in 10 counties are showing the value of on-farm research. Their results are successfully quantifying and predicting the nitrogen needs for growing corn, saving farmers money and reducing environmental impact.
