The objective of this paper was to reveal if soil available heavy metal amount responded to application of fertilizer under Hyllostachys praecox stands. A fertilizer trial was conducted in the main Hyllostachys praecox area
and the amount of soil available heavy metal was analyzed by ICP. Soil available heavy metal (such as Pb
Cd
Zn
Cr and Cu) in all treatments was detected higher at the first sampling time in August and then declining with time until April
afterwards increasing again. There was no difference in soil available Zn and Cr between mixture treatments with different amount of mineral and manure
but significant difference (p<0.05) was found between single mineral treatments with different amount of mineral fertilizer
soil available Zn and Cr increased with the rate of fertilizer. Soil available Pb
Cd
and Cu did not change with the increase of mineral fertilizer rate. Soil available Pb
Cr
and Zn were more abundant in stands with winter mulching practice than with non-mulching practice
1.59
1.30 and 1.26 fold were respective for available Pb
