Top processes

Phosphate sorption on Fe and Al oxides and phosphorus availability

4 steps

Nutrient availability and leaching

1 step

Phosphate sorbed to Fe and Al oxides, precipitated with Ca at high pH

Phosphorus cycling

1 step

Phosphate sorbs to iron and aluminum oxides and becomes occluded

Soil sulfur cycling

1 step

Sulfate in solution is adsorbed on Fe and Al oxides and edge sites, desorbing as pH rises

Pedogenic age sequence: from apatite phosphorus to occluded phosphorus

1 step

Phosphate sorbs to Fe and Al oxides and becomes occluded

Clay mineral transformation sequence

1 step

Gibbsite, goethite and hematite accumulate in extreme weathering

Show 3 more processes

Cation exchange, pH and soil solution chemistry

1 step

Phosphate sorption on Fe and Al oxides and phosphorus availability

Rhizosphere phosphorus mobilization: phosphatases, organic acids and fast re-sorption

1 step

Released phosphate is re-adsorbed to Fe and Al oxides within minutes to hours, so uptake must compete with fast sorption

Nutrient recycling versus new inputs across ecosystem age

1 step

Sorption and occlusion remove phosphorus from the cycle as the soil ages
