- •
The dominant role of Al and Fe(hydr)oxides for accumulating added P was confirmed.
- •
Neoformation of Ca phosphate occurred in 2 of 6 soils after long-term fertilization.
- •
The P K-edge fluorescence intensity was strongly correlated with HCl-digestible P.
- •
In unfertilized, non-calcareous soils, phosphate had a minimum solubility at pH 6–7.
- •
Soil test P (P-AL) was related to the initial adsorbed P calculated from isotherms.
