This experiment was carried out to analyze the effect of liquid pig manure(LPM) application on the amount of heavy metals in paddy soil(Geo-chang) in 2004 and 2005. The analysis of heavy metals in LPM during maturing period, in swine feed which is producted in Gyeong-nam provice and in paddy soil of LPM application plot, Chemical fertilizer application plot and no manure application plot was conducted with ICP(Inductively coupled plasma Emission Spectroscopy, GBC, Australia). The results are as follows. The amount of heavy metals in LPM kept constant during maturing period. and we knew that more amount of copper and zinc was added in swine feed than the requirement amount of copper & zinc in swine. Finally it could be concluded that LPM application did not effective on environmental paddy soil.
