This article is to study the chemical property and organic material of the earthworm casts in three different places. The study shows that the earthworm casts contain plenty mineral elements, in which some toxic element still exist such as As, Cr, Cd, Pb etc. Besides, the earthworm cast is rich in organic material compared to common soil, which can over 60mg/L. What’s more it contains plenty amino acid especially Glu, Asp and Pro. Above all, the earthworm cast contains plenty mineral elements, organic material and amino acid. Thus can be fertilizer. But with some toxic element, it can make negative effect on environment.
