Abstract

Composting is an effective method to clean up the pollution of municipal wastes from the environment. On the other hand, due to the relatively high content of plant nutrients, it may be applied as an ORGANIC FERTILIZER in agriculture. However, the potential of this compound to contaminate soils with heavy metals should be considered. To manage compost application property on soil, the chemical forms of the heavy metals in soil may be studied by SEQUENTIAL EXTRACTION. In this work, effects of MUNICIPAL WASTE COMPOST application on chemical forms of zinc (Zn) and copper (Cu) in a calcareous soil were investigated. Different levels of Isfahan MUNICIPAL WASTE COMPOST as 25, 50 and 100 Mg ha-1 in comparison with a blank and a chemical fertilizer treatment were examined.The experiment carried out for three years. At the first year, the treatments were applied to the whole plot. At the second year, each plot divided into 1/3 and 2/3 portions and the larger portion received the treatment for the second time. At the third year, the larger portion from the last year divided in two halves, one half left without fertilization and the other half was received the fertilizer for the third time. At the end of the third year, soil samples were taken from 0-25 cm depth in different parts of the experimental plots and analyzed for different chemical forms of Zn and Cu using SEQUENTIAL EXTRACTION. The results showed that increase in the amount and the number of MUNICIPAL WASTE COMPOST application increased Zn and Cu concentrations in the soluble (SOL), exchangeable (EXE), carbonate (CAR), occluded (OCC) and organic (ORG) forms. The residual form (RES) did not change for Zn, but increased for Cu. The relative distribution of Zn and Cu in different chemical forms were as follows; RES>ORG>OCC>CAR>EXE>SOL. The results showed that most of the Cu and Zn concentrations were in residual and organic forms therefore, very low concentration can enter the food chain.
