(Phys.org) —In 1900, about 1.6 billion people lived on Earth. Just a few generations later, over four times as many of us share the planet.
An investigation into nitrogen transfers between plants has found that different species can share nutrients through fungal interactions.
A new paper co-written by four University of Montana researchers finds that humans have more than doubled tropical nitrogen inputs.
The most important fertilizer for producing food is, at the same time, one of the most important risks for human health: nitrogen. Chemical compounds containing reactive nitrogen are major drivers of air and water pollution ...
A new study reports that anammox, a key process in the nitrogen cycle, is barely present in Narragansett Bay even though it's a major factor just a little farther out into Rhode Island Sound. Scientists traced that to differences ...
A decades-long debate over how nitrogen is removed from the ocean may now be settled by new findings from researchers at Princeton University and their collaborators at the University of Washington.
Extensive, explosive volcanic eruptions may disrupt a crucial aspect of the global nitrogen cycle, say researchers who have investigated ash deposits on the ocean floor.
It has long been believed that the appearance of complex multicellular life towards the end of the Precambrian (the geologic interval lasting up until 541 million years ago) was facilitated by an increase in oxygen, as revealed ...
Every year waste treatment facilities in the United States process more than eight million tons of semi-solid sewage called biosolids—about half of which is recycled into fertilizer and spread on crop land.
As food security becomes an increasingly important global issue, scientists are looking for the best way to maintain the organic matter in soils using different methods of fertilization and crop rotation.
