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 ...

Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers report iron oxides can drive the same conversion at comparable ...
