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 ...

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 ...

Most phosphorus in the environment is in an organic form that plants cannot directly use, and traditional understanding suggested only enzymes could convert it into the bioavailable inorganic form.

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 ...

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 ...

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 ...
