Abstract: Ten composite soil samples (0-15 cm depth) were collected from
abandoned phosphate-mined sites on Nauru Island (Central Pacific) and
analyzed for % organic C and % N. The samples represent a temporal sequence
(chronosequence) of soil development spanning < 55 yr. The increase of% C and
% N was fairly rapid. In recently mined sites « 1 yr) the values of % C
were between 0.41 and 0.48, and those for % N were between 0.03 and 0.04.
Fifty-five years after mining, the values of % C and % N were 4.56 and
0.33, respectively, and comparable to the amounts found in undisturbed
Lithic Haplustolls, Typic Haplustolls, and Lithic Ustorthents epipedons. These
changes in soil properties are considered to be a function of time and the
accompanying seral development of vegetation (particularly the fern cover of
Nephrolepis biserrata and Polypodium scolopendria) , because parent materials,
climate, and other factors of soil formation are considered to be constant. Rate
of soil development is faster in the unconsolidated sands and limestone rubble
of the pit bottoms and slower on the dolomitic limestone pinnacle surfaces.
