These human activities convert nitrogen from inactive to reactive forms. “Before the Haber-Bosch process and fossil fuel combustion, specialized microbes in the soil could fix nitrogen into forms ...

Scientists at climate talks say major changes to the nitrogen cycle cannot be ignored Date: December 8, 2009 Source: International Geosphere-Biosphere Programme (IGBP) ...

After more than a decade of research and collaboration, researchers from Michigan Technological University, Baylor University and Boston University have discovered that inland and coastal aquatic ...

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.

A new study shows that nitrogen-feeding organisms exist all over the deep ocean, and not just in large oxygen-depleted 'dead zones,' changing the way we think about the delicate nitrogen cycle.

The nitrogen cycle — which has existed for billions of years — transforms non-biologically useful forms of nitrogen found in the atmosphere into various biologically useful forms that are needed by ...

The Nitrogen Cycle. We begin our discussion of the N cycle in a typical grain crop rotation (corn, wheat, double-crop soybean) by considering the plant residue left on the field surface after harvest.

Originally published as “Repair the Nitrogen Cycle in Your Garden” in the April/May 2023 issue of Mother Earth News and regularly vetted for accuracy. Continue Reading. Suggested Video.

Living organisms need nitrogen as a central building block for protein formation, for example. However, although our atmosphere contains plenty of nitrogen, neither humans nor the vast majority of ...
