Abstract

In order to investigate the effect of nickel (Ni) and cadmium (Cd) resulting from SEWAGE SLUDGE (SS) and MUNICIPAL SOLID WASTE (MSW) contamination on the amount of MICROBIAL RESPIRATION and acid and ALKALINE PHOSPHATASE enzymes activity, a field experiment was conducted as randomized complete block design in split-plot arrangement with three replications in 2008. The main plot was SS and MSW at three levels (0, 20 and 40 ton/ha) and sub-plot, period of application (2006, 2006 and 2007, 2006-2008) was considered. The results showed that application of SS and MSW in the different treatments was significant on amount of HEAVY METALs and biological factors. Application of 40 ha-1 ton SEWAGE SLUDGE, for three continuous years, increased the accumulation of Ni and Cd (total and available) in soil and decreased the acid and alkaline phosphates enzymes activity, but the accumulation of Ni and Cd did not have any negative impact on MICROBIAL RESPIRATION in all treatments. The total amount of Ni and Cd showed positive correlation (P<0.05) with the amount of MICROBIAL RESPIRATION and negative correlation (P<0.05) with acid and alkaline phosphates enzymes activity, respectively. Therefore, long-term application of SS and MSW, in addition to accumulation of HEAVY METALs, can decrease enzyme activity and increase soil MICROBIAL RESPIRATION.
