FOR his presidential address to the Geological Section of the Congress of the South Eastern Union of Scientific Societies, held on October 14, Dr. K. P. Oakley took as his subject "Man and the ...

Phosphorus is one of the most common substances on Earth. An essential nutrient for every living organism—humans require approximately 700 milligrams per day—we are rarely concerned about consuming ...

Crops often receive beneficial nutrients such as phosphorus (P) from manure or commercial fertilizer applications. However, the Delaware Nutrient Management Law (3 Del. C. § 2247) limits the amount of ...

Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers found that iron oxide in soil performs the same transformation ...

Phosphorus is a building block of all living cells. It is part of the structure of DNA. Cells use it to make membranes and many other molecules used in metabolism. In the earth's current environment, ...

When Hennig Brandt discovered the element phosphorus in 1669, it was a mistake. He was really looking for gold. But his mistake was a very important scientific discovery. What Brandt couldn't have ...

Northwestern University researchers are actively overturning the conventional view of iron oxides as mere phosphorus "sinks." A critical nutrient for life, most phosphorus in the soil is organic—from ...

Disrupting Earth’s chemical cycles brings trouble. But planet-warming carbon dioxide isn’t the only element whose cycle we’ve turned wonky—we’ve got a phosphorus problem too. And it’s a big one, ...

You know that greenhouse gases are changing the climate. You probably know drinking water is becoming increasingly scarce, and that we’re living through a mass extinction. But when did you last worry ...

Iron oxide in soil performs the same transformation as plants and microbes that are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Northwestern ...

Northwestern University-led researchers have discovered a new way that nature cycles phosphorus, a finding that uncovers a missing piece of Earth’s puzzling phosphorus cycle. The research will be ...
