Abstract

The P status of an unpolluted Cambisol was compared with that of a polluted Cambisol receiving high P deposition that arise from a fertilizer factory near Novgorod, NW Russia. Experiments included P fractionation, P adsorption experiments and 31P NMR spectroscopy. In the O, A and AB horizons of the unpolluted soil organic P was the dominating fraction. Anthropogenic P accumulation was restricted to the O, A and AB horizons and amounted 692 kg ha−1, representing the sum of P deposition within 20 years of factory operation. Most of the additional P was extractable inorganic P. Hence, P extractability increased from 54‐75 % in the unpolluted soil to 66‐83 % in the polluted soil. Ca‐phosphates were mainly accumulated in the forest floor, while Al‐ and Fe‐phosphates were concentrated in the A and AB horizons. Organic P showed only a slight increase due to P deposition. This increase was only due to accumulation of stable monoester‐P, while the stock of the more labile diester‐P and phosphonates in the polluted soil was only half of that in the unpolluted soil.
