Soil analysis revealed a strong trend towards increasing total C content of soil, but only minor increases in oxidisable organic C (by Walkley-Black method) were detected.
The amount of SOC determined using 5, 10, and 20mL of concentrated [H.sub.2][SO.sub.4] when compared with TOC allowed separation of TOC into the following 4 different fractions of decreasing oxidisability: fraction I ([C.sub.frac1]) organic C oxidisable under 12N [H.sub.2][SO.sub.4]; fraction II ([C.sub.frac2]), the difference in SOC extracted between 18N and 12N [H.sub.2][SO.sub.4]; fraction III ([C.sub.frac3]), the difference in SOC extracted between 18 N and 24 N [H.sub.2][SO.sub.4] (the 24 N [H.sub.2][SO.sub.4] is equivalent to the standard WB method); and fraction IV ([C.sub.frac4]), residual organic C after reaction with 24 N [H.sub.2][SO.sub.4] when compared with TOC.
Many reports have shown that during the initial phase of decomposition, O-alkyl C is the first SOC component to decrease, as it is dominated by easily oxidisable organic compounds (Mathers et al.

DOC concentration in the filtrate was measured using a total oxidisable C analyser (Shimadzu, Japan).
According to the modified BCR sequential extraction method, heavy metals exist in soil in four fractions: acetic acid-soluble, reducible, oxidisable and residual (Rodriguez et al.
(D) Walkley-Black oxidation, determined colourimetrically, converted from readily oxidisable C using a factor of 1.72.
Fraction 1 (very labile): organic C oxidisable under 12 N [H.sub.2]S[O.sub.4]; Fraction 2 (labile): difference in oxidisable organic C extracted between 18 N and 12 N [H.sub.2]S[O.sub.4] (18 N-12N [H.sub.2]S[O.sub.4]); Fraction 3 (less labile): difference in oxidisable organic C extracted between 24 N and 18 N [H.sub.2]S[O.sub.4] (24 N-18N [H.sub.2]S[O.sub.4]); and Fraction 4 (recalcitrant): difference in organic C extracted with 24 N [H.sub.2]S[O.sub.4] and TOC (TOC-24N [H.sub.2]S[O.sub.4]) (Benbi et al.

In the present study we investigated changes in total SOC, as well as in the concentration and distribution of oxidisable organic carbon fractions in rhizospheric and bulk soils of Chinese pine following N addition in pot experiments.
