Abstract

Organic matter based on their composition and the C/N ratio can have different effects on nutrient bioavailability in soil. This research was conducted to investigate the effects of various sources of organic fertilizers on bioavailability of Cu and Zn in soil. A silty clay soil sample and three organic fertilizers including ANIMAL MANURE, SEWAGE SLUDGE and MUNICIPAL COMPOST in two levels of 1.25 and 2.5% W/W bases were included for the experiment. The experiment was conducted in two stages of incubation and greenhouse cultivation of CORN (Zea mays L.). Both experiments were in factorial complete randomized design with 6 treatments in 4 replications plus the control. In the first experiment treated soils were incubated at field capacity moisture and 25oC temperature for 8 weeks during which subsamples were taken at 0, 4 and 8 weeks and were analyzed for available Zn and Cu. The results showed that the highest amount of DTPA extractable Zn were 148.4 and 156.7 mg kg-1for the sewdge sludge at the 1.25 and 2.5 percent treatments respectively, and the lowest was related to manure treatment with 103.7 mg kg-1. The highest amount of DTPA axtractable Cu was for the compost treatment with 28.1 and 28.4 mg kg-1in the levels used, and it was 28.4 mg kg-1in the swedge sludge treatment at 2.5% level. Comparison of the changes over time showed that available Zn content decreased but Cu content increased up to 4 week and then decreased. The results of the greenhouse experiment showed that all treatments except sewdge sludge increased some plant growth factors such as yield Zn content and the highest Zn and Cu uptake by plant were in the sewdge sludge treatment with 18.8 and 1.15 mg kg-1.
