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 ...

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 (P) is an important nutrient element in plant photosynthesis. However, the adsorption of mineral P via leaching and erosion leads to a decrease in P availability and consequently P ...

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 ...

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 ...
