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 — ...

Scientists know iron oxide minerals store large amounts of carbon in soils, but lack a detailed, quantitative understanding of the specific chemical mechanisms that allow them to bind such a wide ...

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.
