Top processes
- Soil solution holds only about 1 to 10 micromolar phosphate, far less than the amount in the solid phase
- Phosphate displaces OH and OH2 on goethite, gibbsite and allophane surfaces, forming inner-sphere complexes
- Sorption capacity scales with oxalate-extractable Al + Fe, and saturation degree is phosphate divided by 0.5 times (Al + Fe)
- and 5 more in this process
- Soil solution Phosphate seldom exceeds about 10 uM (often 1-2 uM), so roots deplete a zone around themselves
- Low Phosphate induces plant and microbial phosphatases and phytases that hydrolyse organic P (about 30-65% of total soil P in many soils)
- Roots and microbes exude citrate, malate and oxalate and extrude H+ to desorb phosphate from Fe and Al oxides and dissolve Ca phosphates
